A Prayer of St. Ambrose: c.339-397 link
O Lord, who hast mercy upon all, take away from me my sins, and mercifully kindle in me the fire of thy Holy Spirit. Take away from me the heart of stone, and give me a heart of flesh, a heart to love and adore thee, a heart to delight in thee, to follow and to enjoy thee, for Christ’s sake.
A Morning Prayer: Syrian Clementine Liturgy link
O God, Who are the unsearchable abyss of peace, the ineffable sea of love, the fountain of blessings, and the bestower of affection, Who sends peace to those that receive it; open to us this day the sea of Your love, and water us with the plenteous streams from the riches of Your grace. Make us children of quietness, and heirs of peace. Kindle in us the fire of Your love; sow in us Your fear; strengthen our weakness by Your power; bind us closely to You and to each other in one firm bond of unity; for the sake of Jesus Christ.
Nicene Creed link
We believe in one God,
the Father almighty,
maker of heaven and earth,
of all things visible and invisible.
And in one Lord Jesus Christ,
the only Son of God,
begotten from the Father before all ages,
God from God,
Light from Light,
true God from true God,
begotten, not made;
of the same essence as the Father.
Through him all things were made.
For us and for our salvation
he came down from heaven;
he became incarnate by the Holy Spirit and the virgin Mary,
and was made human.
He was crucified for us under Pontius Pilate;
he suffered and was buried.
The third day he rose again, according to the Scriptures.
He ascended to heaven
and is seated at the right hand of the Father.
He will come again with glory
to judge the living and the dead.
His kingdom will never end.
And we believe in the Holy Spirit,
the Lord, the giver of life.
He proceeds from the Father and the Son,
and with the Father and the Son is worshiped and glorified.
He spoke through the prophets.
We believe in one holy catholic and apostolic church.
We affirm one baptism for the forgiveness of sins.
We look forward to the resurrection of the dead,
and to life in the world to come.
The Benediction of Jude 24-25 link
Now to him who is able to keep you from stumbling and to present you blameless before the presence of his glory with great joy, to the only God, our Savior, through Jesus Christ our Lord, be glory, majesty, dominion, and authority, before all time and now and forever.
