Psalm 50 LXX

Psalm 50 is a model of genuine repentance. It is used frequently within the services of Orthodox Churches and is included most personal prayer rules.

King David committed the sins and transgressions of adultery and murder. However, he obtained mercy from God because of his repentance. King David’s genuine repentance before God is a model for genuine repentance for the sins and transgressions that we ourselves have committed.

Psalm 50

Have mercy upon me, O God, according to Your great mercy;
and according to the abundance of Your compassion, blot out my transgression.
Wash me thoroughly from my lawlessness and cleanse me from my sin.
For I know my lawlessness, and my sin is ever before me.
Against You only have I sinned and done evil in Your sight;
   that You may be justified in Your words, and overcome when You are judged.
For behold, I was conceived in transgressions, and in sin my mother bore me.
Behold, You love truth;
   You showed me the unknown and secret things of Your wisdom.
You shall sprinkle me with hyssop, and I will be cleansed;
   You shall wash me, and I will be made whiter than snow.
You shall make me hear joy and gladness;
   my bones that were humbled shall greatly rejoice.
Turn Your face from my sins, and blot out all my transgressions.
Create in me a clean heart, O God, and renew a right spirit within me.
Do not cast me away from Your presence, and do not take Your Holy Spirit from me.
Restore to me the joy of Your salvation, and uphold me with Your guiding Spirit.
Then I will teach transgressors Your ways, and the ungodly shall turn back to You.
Deliver me from blood-guiltiness, O God, the God of my salvation,
   and my tongue shall greatly rejoice in Your righteousness.
O Lord, You shall open my lips, and my mouth shall declare Your praise.
For if You desired sacrifice, I would give it;
   You will not be pleased with whole burnt offerings.
A sacrifice to God is a broken spirit,
   a broken and humbled heart God will not despise.
Do good, O Lord, in Your good pleasure to Zion;
   and let the walls of Jerusalem be built.
Then You will be pleased with a sacrifice of righteousness,
   with offerings and whole burnt offerings.
Then they shall offer young bulls on Your altar [and have mercy on me, O God].

— Psalm 50, as heard in Matins

The Wedding Garment: Making the Most of What Christ Offers

Sdn Tim Grace

September 6, 2026 10:00 AM

Preaching on Father's Day, Sub Dn. Timothy Grace takes up the parable of the wedding feast and the guest without a garment. In the ancient world the host supplied the garments, so to arrive without one was not poverty but insult — and Christ, the great host, has supplied us with everything we need. Drawing on St. Symeon the New Theologian's call to run to the light while it still shines, he asks what excuse any of us will offer for not becoming holy. He closes with a word to fathers on steering between indifference and control, and on St. Paul as a model of invested, un-domineering fatherhood.

Tenants in the Vineyard: Saved by Grace, Made to Love

Fr. Geoff Harvey

August 30, 2026 10:00 AM

Preaching on the parable of the wicked tenants, Fr. Geoff Harvey holds together two truths that can seem to pull against each other: we are saved by grace and not by works, yet a faith that bears no love has no life in it. The tenants' great failure did not begin with murder but with forgetting whose vineyard it was. Fr. Geoff offers three simple charges — stand firm in the faith, serve one another in love, and show love to the Lord — and points us to the stone the builders rejected, who has become the cornerstone of our salvation.
