Reflection on Psalm 51:10-11

Create in me a clean heart, O God,

and renew a steadfast spirit within me.

Do not cast me away from Your presence,

and do not take Your Holy Spirit from me.

These two verses are part of a penitential psalm prayed by King David after his fall. The psalm begins with: “Have mercy upon me, O God, according to Your lovingkindness; according to the multitude of Your tender mercies, blot out my transgressions. Wash me thoroughly from my iniquity, and cleanse me from my sin. For I acknowledge my transgressions, and my sin is always before me.”

In this penitent prayer, which was certainly accompanied by abundant tears, King David pleaded for a pure heart and a renewal of the spirit. But this prayer also expresses a deep mystery concerning the creation of a new heart. God later promised through the prophet Ezekiel: “I will give you a new heart and … a new spirit.”

David’s plea: “Create in me a clean heart” expresses that the human heart is not pure by nature. It is corrupted by the original sin that we inherit from our first parents. From this spiritual impurity comes not only moral impurity, but also all the evil that man and mankind commits. At that moment, King David, enlightened by the Spirit of God, without perhaps perceiving the full depth of the mystery, nevertheless utters the word: “create”, that is, he longs for a new heart. It is to such a desire that God answers through the prophet Ezekiel: “I will give you a new heart.” That new, immaculate heart is the new Eve, the new woman, namely the Most Holy Mother of God. The spiritual transplant of this new heart took place at the hour of Jesus’ death on the cross. At the foot of the cross stood a disciple to whom Jesus said a short word, but one connected with God’s omnipotence: “Behold your mother.” The disciple responded with faith to this word and accepted a new mother. Eve is the mother of the sinful generation. Mary is the mother of the new generation, and the Son of God Himself is the firstborn.

Especially in today’s age of transhumanism and genderism, which lead to the self-destruction of the individual and humanity, the prophetic word of Fatima applies: “In the end, my Immaculate Heart will triumph.” The Mother of God has an Immaculate Heart, but she is also completely Immaculate. If we have accepted her as our mother and we daily enter this truth by faith, then as our spiritual mother she gives birth to us again in pain until we are transformed into Christ (Gal 4:19). This inner transformation of ours is carried out by the Holy Spirit together with her. So the condition of new life, God’s life in us, is a new heart and the Holy Spirit.

David also pleads for the renewal of a steadfast spirit within him. The Apostle Paul writes in the 8th chapter of Romans: “The Spirit of God testifies with our spirit that we are children of God.” (v.16) So there is our human spirit which is the essence of our soul, and there is the Spirit of God who fills the heart of those who repent.

Scripture also testifies that we, the baptized, are a living temple of the Holy Spirit (1Cor 6:19). However, whoever drives out the Holy Spirit through a grave sin is no longer a temple of God until he truly repents. In this psalm, David motivates us to do what is most needed in a Christian’s life, and that is true penance. He also expresses the need for repentance and a repentant mindset with the words: “My sin is always before me.” God has forgiven our sins, but in order for the soul to be healed, we must again realize what we have been forgiven and mourn our sins again with true sorrow. Also, by doing good, we are to make up for the evil we have done, even though the eternal punishment has been forgiven. But the soul is not yet fully cleansed of sinful inclination. If we do not make satisfaction, a painful purgatory awaits us. A wise Christian cries out with St. Augustine: “Lord, cut me and chastise me here, but spare me torment in eternity (in purgatory).”
