Lesson # 8
God's Plan for a Transformed Heart and Life:
Blessed are the Pure in Heart

Eternal Father,
Your holiness separated us from You, for who can come into the presence of a pure and holy God and live? But so great was Your love for us that You sought to redeem us and all creation through the matter that You originally created as pure and holy but which had been corrupted through the sin of our original parent's Fall from grace. And so You deemed to come to us as God enfleshed "enfleshed in our mortal flesh to breath the air we breath, to drink the water we drink, and to experience creation as we experience creation. But that was not enough. In Your love for us and through the sacrifice of God who is man, You baptized us with the precious blood of Your Son so that we might become part of the New Creation, no longer children of Adam but through Your Son, Jesus Christ, we became children of a pure and holy God. Children in whom a new heart had been planted "a heart called to purity, peace, and self-sacrificial love "a heart to love as Jesus first loved us. Send us Your Holy Spirit to be our teacher, Lord, as we study the promises made to us in the Law of the New Covenant. We pray in the name of God the Father, Son, and Holy Spirit, Amen.

We must begin by purifying ourselves before purifying others; we must be instructed to be able to instruct, become light to illuminate, draw close to God to bring him close to others, be sanctified to sanctify, lead by the hand and counsel prudently. St. Gregory of Nazianzus, Oratio 2, 71 as quoted in CCC# 1589

Blessed are those who observe his instructions, who seek him with all their hearts Psalm 119:2 (New Jerusalem translation)

Who may go up the mountain of the LORD? Who can stand in his holy place? The clean of hand and pure of heart Psalm 24:3-4

When we submit to the sovereignty of God in "poverty of spirit" we take the first step toward our rebirth as sons and daughters of God. In our submission as spiritual children He promises us eternal life in the Kingdom of Heaven and in our rebirth through baptism we come as His New Covenant children before the throne of God. Face to face with a pure and holy God we become aware of our imperfections and taking the next step we mourn our sins and the sins of the world. Our sincere contrition purifies us and He comforts us and strengthens us in our struggle to conquer sin. Drawing close to God we desire to be more perfectly conformed to His will. We yield our selfish will to His eternal will and in a spirit of renewal our Father gives us our inheritance "as His children we conquer in meekness as we serve Him in His Church, the Kingdom of Heaven on earth "an earth that no longer can intimidate or dominate us because we serve the Lord who dominates the earth. United with our Father in spirit and in will, He gives us a hunger and thirst for righteousness as manifested in His Son. This is the turning point in the spiritual journey, when we turn from what we need to give God to our focus on the Son of God and what He will give us. In Christ we die to sin and are raised to righteousness and Jesus feeds us on our journey with His very flesh and blood, such is the depth of His love as He continues to more deeply spiritually transform us to His image "an image that calls for a pure and holy heart as our Savior is pure and holy. We feel the need to empty ourselves of worldly attractions and concerns and to fill our entire being with the love of Jesus our Savior, becoming an imitation of Christ in our lives. Our cry becomes the cry of David, the beloved's in Psalm 51:12 (verse 10 in some translations): A clean heart create for me, God; renew in me a steadfast spirit.

Matthew 5:8: Blessed are the clean of heart for they will see God

Under the Old Covenant Law, ritual purity prepared the Covenant people for the coming of a pure and holy Messiah, but in his homily on the Beatitudes St. Augustan points out that the external ceremonial purity as expressed in the Old Law was not enough. The singleness of heart which submits itself in perfect love to God's will is the purity God seeks. We cannot live the "New Law" of the Beatitudes without Christ any more that the Jews under the Old Covenant could perfectly keep the Law of Moses. In the Old Covenant circumcised flesh was a blood sacrifice which symbolized the sacrifice of self to Yahweh, but it is not circumcised flesh or the sin sacrifice of animals that pleases God.

Question: What personal sacrifice of every believer is pleasing to God? See Deuteronomy 10:16 and 30:6 and David's plea to God in Psalm 51:18-19.

Answer: God requires repentant, humbled / "circumcised" hearts:

The Greek word for "pure" is katharos. It is an adjective meaning "pure as in being cleansed." The heart, or kardia in Greek, is the most vital organ in the human body. We think of our hearts as the internal instrument of our emotions but the ancients did not understand the function of a heart in this way. For the peoples of ancient times, the Jews, Greeks or Romans, different body parts had different physiological functions. The Jews believed that anger was situated in the nose with love, compassion and most other emotions in the kidney, liver and bowels. To the people of Jesus' time the heart reflected the total substance of a man or woman; the inward part of a person as opposed to what is visible. Hearing this beatitude the Jews and Israelites listening would think of the heart as the center of the faculties and personality, the seat of knowledge and understanding "not just feelings but also thoughts, words, decisions and actions proceed from the heart. The inspired writers of Scripture recognized that depravity and deceit emerge from the human heart as sin, doing its greatest damage to the inward life from which sin then defiles the whole man or woman (see Matthew 15:19-20). But the inspired writers of Sacred Scripture also recognized that the heart represented the hidden depths of one's spiritual being and regarded the heart as the focus of divine influence from which a man or woman could be purified by God from the inside out (see Romans 2:15; Acts 15:9 and 1Peter 3:4).

Jesus identified the heart as the seat of forgiveness when He warned the crowds, in the parable of the Merciless Servant, of the punishment inflicted on one who refuses to forgive: So my heavenly Father will do to every one of you, if you do not forgive your brother from your heart (Matthew 18:35); identifying the depths of one's heart as the place where the pain inflicted by others in our lives is either "bound or loosed." Jesus taught that the Covenant believer who offers his heart to the Holy Spirit is released from the earthly power to continually feel a hurt; instead the Holy Spirit turns that hurt into compassion and purifies the believer's heart by turning that hurtful memory into intercession and prayer for the offender, as we forgive those who trespass against us (Matthew 5:12), for it is our infirmities that he bore, our sufferings that he endured, by his stripes we were healed (Isaiah 53:4-5, prophecy of the Suffering Messiah). Also see The Lord's Prayer, Matthew 5:43-44, and CCC # 2842-44]. Therefore, when Jesus spoke of the blessedness of a cleansed heart, His 1st century listeners understood He was speaking of the total reflection of a person called to purity in every aspect of his or her life.

Question: What else does Scripture teach about the heart?

  1. What does the Bible teach about the heart in Psalm 17:3; 1Samuel 16:7; and Psalm 44:22 (21)?
  2. What does the Bible teach about the heart in Ezekiel 36:26-27; Psalms 51: 12(10), 19 (17); and Jeremiah 4:4; 31:31-33?
  3. What does the Bible teach about the heart in Deuteronomy 4:29; Psalms 105:3; and Psalm 119:2, & 10?
  4. What does the Bible teach about the heart in 1Kings 3:9; Hosea 2:16; and Deuteronomy 30:11-14?
  5. What does the Bible teach about the heart in 1 Samuel 12:20, 24; Deuteronomy 6:5-6; and Psalm 111:1?


  1. God knows the depth of each human heart: You have tested my heart, searched it in the night. You have tried me by fire, but find no malice in me (Psalm 17:3). Also see 1 Samuel 16:7; Psalm 44:22(21).
  2. The heart represents the center of religious/spiritual awareness and morality: I will give you a new heart and place a new spirit within you. Taking from your bodies your stony hearts and giving you natural hearts. I will put my spirit within you and make you live by my statutes, careful to observe my decrees (Ezekiel 36:26-27). Also see Psalms 51: 12(10), 19 (17); Jeremiah 4:4; 31:31-33.
  3. It is from the heart that we must seek God: Yet there too you shall seek the LORD, your God; and you shall indeed find him when you search after him with your whole heart and your whole soul (Deuteronomy 4:29). Also see Psalms 105:3; 119:2, 10.
  4. It is from the heart that we listen to God and to hear Him speak to us: Give your servants, therefore, an understanding heart to judge your people and to distinguish right from wrong (1Kings 3:9). Also see Hosea 2:16; Deuteronomy 30:11-14.
  5. It is from the heart that we must serve Him, praise Him, and love Him:

Question: The word "spirituality" is one of the most poorly defined and most often abused words in the Christian vocabulary. Even Buddhists and Hindus are "spiritual" people. Biblically is it correct to define "Christian spirituality" or "the Christian spiritual life" as simply a "feeling" of closeness to God? Look up the word "spiritual" or "spiritual life" in a Catholic dictionary.

Answer: As defined by the abridged edition of the Modern Catholic Dictionary "spiritual life" is: the life of the Holy Spirit, dwelling in the souls of the faithful and enabling them to praise and love God and serve him in the practice of virtue. It is called the spiritual life because: 1. its animating principle is the Spirit of God, the "Soul of the soul" in sanctifying grace; 2. it is the supernatural life of the human spirit; 3. it is mainly lived out in the spiritual faculties of intellect and will, although affecting the whole person, body and soul (Modern Catholic Dictionary, abridged edition, page 417).

It is the "spiritual" believer who seeks to serve God with a clean heart. Scripture tells us it is those of "clean hearts" who will turn to God with no reservations, with no hypocrisy, but with only genuine repentance for sin and with love and obedience. St. Jose-Maria Escriva wrote: A man is worth what his heart is worth, and St. Paul the Apostle's prayer for the community at Ephesus was: May he [God] enlighten the eyes of your heart so that you can see what hope his call holds for you, how rich is the glory of the heritage he offers among his holy people (Ephesians 1:18). [Note: most translations have "eyes of your mind" but the literal translation is "heart"; see New Jerusalem page 1933 note "r"].

Psalms 24 connects the clean or pure in heart with the "righteous" believers who worship Yahweh in the Temple. According to Jewish tradition, it was Psalm 24:1-10 which was sung on the first day of each week in the Temple worship services in Jerusalem.

Question: If this psalm was indeed sung on the "first" day of the week, what was that day and what was its significance? Hint: the 7th day, the Old Covenant Sabbath, was Saturday.

Answer: The first day of the week was our "Sunday". For the Old Covenant people it was the day Creation began. For the New Covenant people it will be the first day of the New Creation when Jesus arose from the dead!

Please read Psalm 24:1-10. This passage defines the character the worshippers who are clean of heart. Verses 3-6 identify who is worthy to join in the liturgical celebration.

Question: Who is it who is worthy to come to Yahweh's Temple and offer worship to God as identified in verse 4?

Answer: The clean of heart, or literally in the Hebrew "the one whose hands are clean". The singular is used but the identification is for the entire class of righteous worshippers.

Question: How does Psalm 24:3-6 define those of pure hearts "the righteous believers?

Answer: As for the clean of heart:

Question: In Psalm 24:7-10 who is the King of Glory for whom the faithful Covenant people of pure hearts wait?

Answer: The King of Glory is also identified in the Old Testament as Yahweh Sabaoth, the Lord of Hosts, commander of the heavenly army. The Old Covenant faithful came to understand this aspect of Yahweh's authority to be embodied in the promised Messiah of Daniel 7:13-14, eternal, holy and mighty! This psalm was one of the messianic psalms that looked forward to the coming to the Davidic King who would rule Israel and the Church forever! We know Him as Jesus of Nazareth.

Jesus' standard for purity of heart requires that the piety of the believer depends on an inward transformation and not only on an outward show of ritual piety. In Matthew 6:21 Jesus will teach that one's heart must be in heaven, where one's treasure is to be found: For where your treasure is, there also will your heart be. Purity of heart then identifies the true internal self of the believer in union with God. Purity of heart is to will only one thing and that is conformity with God's will with all of one's being "internally and externally in one's thoughts, words and actions. This is the kind of man or woman who "knows the heart of God."

Question: Of all the Old Testament heroes and heroines who is identified as one who was "after God's own heart?" See 1 Samuel 13:14 and 16:1-13.

Answer: David the shepherd-boy, musician, poet-warrior, lover of beautiful woman, adulterer, and murderer who was King of Israel. He was an imperfect man who yearned throughout his life to present himself to his God in perfect purity of heart.

With all his imperfections why did God so love David? There are many incidents in the Bible stories of David's life which illustrate his relationship with God. For example:

Please read 2 Samuel 12:13-25 and then answer these questions:
Question: If God had truly forgiven David (2 Samuel 12:13), then why was it that the innocent child born from their illicit union had to die?

Question: Why did David grieve and prostrate himself before the Lord in fasting and prayer so long as the child lived, but as soon as the child died why is it that David ceased his mourning?

Question: Why, despite his many faults, did God love David?

Answers: As a result of his sincere contrition and repentance David's sin was forgiven but there remained the accountability for sin and therefore it was God's judgment that David had to forfeit the life of the beloved child. It may seem cruel to us but God is not cruel "for an innocent child to come "home" to heaven is not a sad event from God's perspective. David was suffering the "double consequence" of sin. Mortal sin is a direct, knowledgeable, and willful disregard for the commands of God. Mortal sin deprives us of communion with God and therefore makes us incapable of receiving God's gift of eternal life without forgiveness through the sacrifice of Christ. However, every sin, including venial sin, is still sin and must be purified "either here on earth through our suffering as a consequence of that sin, through contrition and penance as expressed in acts of charity, or after death in the state which the Church identifies as Purgatory. In Old Testament times the dead were consigned to Sheol, the grave, which contained the righteous dead separated from the unrighteous who experienced the punishment for their sins (see Matthew 18:34-35 & CCC# 633; 1030-32). This purification of "cleansing fire" frees one of the "temporal punishments" of sin. The Catechism teaching on this subject records: All who die in God's grace and friendship, but still imperfectly purified, are indeed assured of their eternal salvation; but after death they undergo purification, so as to achieve the holiness necessary to enter the joy of heaven (CCC# 1030). However, in David's case, the forgiveness of sin which resulted in the restoration of communion with God addressed the remission of his separation from God and reestablished David's fellowship with God, but the temporal punishment of his sin remained because David was still accountable for the sin he had brought into the world (see CCC #1472 -73).

In spite of the Prophet Nathan's pronouncement that the child would die, David sincerely continued to repent his sin and in an act of contrition he fasted and prayed that the child's life might be spared. So long as there was hope that God would show mercy David persisted in prayer, but when the child died David completely accepted the will of God. It was David's sincere desire to conform his will to the will of God that gave him the kind of heart that earned him the name of God's "beloved" and a man "after God's own heart". David in Hebrew [DWD in proto-Hebrew and dawid, with vowels] means, "beloved" (Dictionary of the Bible, John L. McKenzie, S.J.).

But purity of heart cannot come from our own internal cleansing. Jesus told his disciples: You are pure because of the word which I have spoken to you (John 15:3). We can only have a clean heart through the supernatural grace of God.

Question: What is the supernatural gift of grace by which our hearts are cleansed?

Answer: God the Holy Spirit. Purity of heart can only come about through the work of God the Holy Spirit. He is our gift from the Father and the Son to be the source of living water welling up from the heart of Christ and flowing out to every believer [see John 7:38]. He puts Christ in our hearts, circumcising our old hearts and giving us a new heart conforming us to His image. It is Christ dwelling in us who gives us a truly purified interior self. When St. Paul wrote I live now not I but Christ lives in me in Galatians 2:20, he wanted us to understand that our deepest identity is to be Christ "it is the only way we will be able to return to the pre-Eden "image of God." And what is the result? It is that whatever you do, or say, or see reflects the image of God. St. Paul wrote to St. Titus in Titus 1:15: Everything is pure to the pure! A pure heart beats to the living revelation of Jesus Christ!

David struggled with cleanliness of heart and often failed. But in his failure he always knew where to turn "repeatedly he turned back to God. For us the call for a cleansed heart is so much easier because Christ's sacrificial death has purified us through His precious blood. Through the work of the Holy Spirit He has "circumcised" our hearts "He has given us new hearts conformed to His precious sacred heart and this transformation has given us a unique promise "to see the face of God.


"Blessed are the pure in heart, for they shall see God." It is true, because of the greatness and inexpressible glory of God, that "man shall not see me and live"; for the Father cannot be grasped. But because of God's love and goodness toward us, and because he can do all things, he goes so far as to grant those who love him the privilege of seeing him for "what is impossible for men is possible for God."
St. Irenaeus, Against Heresies, IV.20.5

The LORD is just and loves just deeds; the upright shall see his face. Psalm 11:7

Strive for peace with everyone, and for that holiness without which no one will see the Lord. Hebrews 12:14

Question: In Sacred Scripture who are the few given this very special privilege? Can you name at least one such encounter?

Answer: Everyone who saw the face of Jesus of Nazareth literally saw the face of God. Moses, Aaron and his two sons, and the 70 elders of Israel ate a meal in God's presence during the sacrificial meal that ratified the Sinai Covenant in Exodus 24:9-11. Verse 10 records that they beheld the God of Israel, and in verse 11: After gazing on God, they could still eat and drink. In Exodus 33:11, Scripture records that The LORD used to speak to Moses face to face, as one man speaks to another. But it is uncertain if these men literally saw God's face because in Exodus 33:20 Yahweh warns Moses: But my face you cannot see, for no man sees me and still lives, and St. John writes in John 1:18: No one has ever seen God; it is the only Son, who is close to the Father's heart, who has made him known.

In the New Covenant, Jesus tells His disciples that to see God is the promise for those of "clean hearts." This is a promise that can have two fulfillments; one in the present and another in the future.

Question: In what two ways can this promise be fulfilled, present and future?

Answer: This promise not only concerns the promised beatific vision in the spiritual body for those who experience a holy death and come face to face with God in the eternal kingdom, but to experience God on this earth through works of mercy and kindness in which one sees the face of God in each person to whom love and comfort is given in the name of Jesus the Messiah.

We were created, after all, in the image and likeness of God "an image that was damaged in our original parent's fall from grace. In the Old Covenant that "image" was partially restored to those who remained in covenant with God and who received a divine call to obedience in a predestined role in Salvation History. For example in the Old Testament the title "son of God" was applied to those in the covenant with God continued through Adam's righteous son Seth (see Genesis 6:2-4), as in the sons of Abraham through Isaac and his son Jacob and Jacob's sons who were the physical fathers of the 12 Tribes of Israel (Exodus 4:22; also Hosea 11:1); for those who received a special anointing by God, as in a king of Israel from David's line (2 Samuel 7:12-17; Psalm 2:7); and for angels as divine messengers [the Greek word angelos means messenger and was also a term designated for prophets] who were also called "sons of God" (see Deuteronomy 32:8; Job 38:7). But that perfection of grace that was lost to humanity in the Fall was restored through Jesus' sacrificial death and resurrection by God the Holy Spirit so that in the New Covenant in Christ our image and likeness of God can be restored. St. John promises the faithful in 1 John 3:2-3: Beloved, we are God's children now; what we shall be has not yet been revealed. We do know that when it is revealed we shall be like him [Jesus]. For we shall see him as he is. Everyone who has this hope based on him makes himself pure, as he [Christ] is pure. It is Christ dwelling in us who makes us pure (See CCC# 359).

The Dominican scholar Father Raymond of Capua, the spiritual director, friend, and biographer, of St. Catherine of Siena [1347-1380] records St. Catherine told him at one time she had a devotion to repeating Psalm 51:12 (verse 10 in some translations): A clean heart create for me, God; renew in me a steadfast spirit. Then one day she had a vision in which the Lord came to her, removed her physical heart and inserted a new heart, telling her that He was giving her His own heart. Later, when Catherine was gravely ill, Father Raymond visited her. As he sat by her bed he saw her countenance change and he suddenly realized that he was looking into the face of Christ Himself (Life of Catherine of Siena, by Raymund of Capua). St. Catherine had what St. Paul of Tarsus had also discovered and that is purity of heart means dying to self and living for Christ. To have purity of heart we must claim what St. Paul claimed for himself in Galatians 2:19b-20: I have been crucified with Christ; yet I live, no longer I, but Christ lives in me; insofar as I now live in the flesh, I live by faith in the Son of God who has loved me and given himself up for me. Mother Therese of Calcutta understood what it truly meant to die to self and live for Christ. The Christ living in her heart allowed her to see the face of Christ in the face of every suffering man and woman she washed and clothed and bathed and helped to die with dignity.

The inspired writer of the New Testament book of Hebrews links "seeing God" with holiness, with comes through purity of heart, and peacemaking: Seek peace with all people and the holiness without which no one can ever see the Lord. Filling our hearts with Christ produces a purity of spirit that produces in our hearts peace that overflows out of our hearts and touches each person we meet " a right relationship with God leads to the desire for a right relationship with others. When our clean hearts overflow with Christ's love we are promised the peace of God that surpasses all understanding will guard your hearts and minds in Christ Jesus (Philippians 4:7). The result is that we become His emissaries; bearers of Christ bearing peace.

The sixth step on the road to salvation and the sixth promise:

Blessed are the pure of heart:
our old hearts are replaced
with the pure heart of
Jesus our Redeemer à
we will see God's face in the
faces of everyone with whom
we share His love.

Questions for group discussion:

The clean of heart are those who have souls of righteousness. Read the contrast of the righteous man as opposed to the man who in clings to wickedness in Wisdom 1:1- 3:11.

Question: Is what comes out of one's mouth a good way to determine "purity of heart?" What are those words from one's mouth that indicate a "heart cleaning" is in order through repentance and prayer?

Question: Is what one's mind and eyes are drawn to also a factor in determining "purity of heart?" Why?

Question: Some family traits are inherited: eye color, hair color, natural abilities. Other traits are learned: truthfulness, sincerity, honesty, dealing with anger, etc. What traits have we inherited through our baptism from our Heavenly Father? What traits are learned from Mother Church? How should we struggle against that inherited trait from the family of Adam called "concupiscence"? Concupiscence = a word from the Latin, con = thoroughly + cupere, to desire. As defined by the Modern Catholic Dictionary concupiscence is The insubordination of man's desires to the dictates of reason, and the propensity of human nature to sin as a result of original sin. There are two aspects to concupiscence:

  1. Concupiscence of the Eyes = Unwholesome curiosity and an inordinate love of this world's goods. The first consists in an unreasonable desire to see, hear, and know what is harmful to one's virtue, inconsistent with one's state of life, or detrimental to higher duties and the other is
  2. Concupiscence of the Flesh = The inordinate love of sensual pleasure, to which fallen man is naturally prone.
