Prayer to the Holy Trinity

It is just and fitting, in reverence to God, to glorify and praise You, Holy Trinity, indivisibly one and unique in Your all infinitely surpassing being — You, our merciful God. All earthly beings honor You, and the heavenly spirits glorify You. The one divine Essence, who lives in three Persons, to You we, all the faithful, bring our God‑dependent bow.

Father Almighty, Son and Divine Word, Most Holy Spirit, the one power and authority, the one kingdom and majesty, forgive and have mercy, heal and save us, who firmly trust in You and acknowledge You as our God, who ever pray to You, who always desire to serve You, diligently fulfilling Your will, commandments and teachings, and to love and honor You ever more.
Amen
