Prayer of St. Augustine of Hippo, 354-430 link
Lord Jesus, let me know myself and know Thee, And desire nothing save only Thee.
Let me hate myself and love Thee.
Let me do everything for the sake of Thee.
Let me humble myself and exalt Thee.
Let me think nothing except Thee.
Let me die to myself and live in Thee.
Let me accept whatever happens as from Thee.
Let me banish self and follow Thee, and ever desire to follow Thee.
Let me fly from myself and take refuge in Thee,
that I may deserve to be defended by Thee.
Let me fear for myself, let me fear Thee, and let me be among those who are chosen by Thee.
Let me distrust myself and put my trust in Thee.
Let me be willing to obey for the sake of Thee.
Let me cling to nothing save only to Thee, and let me be poor because of Thee.
Look upon me, that I may love Thee.
Call me that I may see Thee, And forever enjoy Thee.
A prayer of St. Clement of Alexandria link
O Educator, be gracious to thy children, O Educator, Father,
Guide of Israel, Son and Father, both one, Lord. Give to us,
who follow thy command, to fulfill the likeness of thy image,
and to see, according to our strength,
the God who is both a good God and a Judge who is not harsh.
Do thou thyself bestow all things on us who dwell in thy peace,
who have been placed in thy city, who sail the sea of sin unruffled,
that we may be made tranquil and supported by the Holy Spirit,
the unutterable Wisdom, by night and day,
unto the perfect day, to sing eternal thanksgiving
to the one only Father and Son, Son and Father, Educator and Teacher with the Holy Spirit.
The Nicene Creed link
I believe in one God, the Father Almighty, Maker of heaven and earth, and of all things visible and invisible.
And in one Lord Jesus Christ, the only-begotten Son of God, begotten of the Father before all worlds; God of God, Light of Light, very God of very God; begotten, not made, being of one substance with the Father, by whom all things were made.
Who, for us men for our salvation, came down from heaven, and was incarnate by the Holy Spirit of the virgin Mary, and was made man; and was crucified also for us under Pontius Pilate; He suffered and was buried; and the third day He rose again, according to the Scriptures; and ascended into heaven, and sits on the right hand of the Father; and He shall come again, with glory, to judge the quick and the dead; whose kingdom shall have no end.
And I believe in the Holy Ghost, the Lord and Giver of Life; who proceeds from the Father [and the Son]; who with the Father and the Son together is worshipped and glorified; who spoke by the prophets.
And I believe one holy catholic and apostolic Church. I acknowledge one baptism for the remission of sins; and I look for the resurrection of the dead, and the life of the world to come.
Christ with me, Christ before me, Christ behind me,
Christ in me, Christ beneath me, Christ above me, Christ on my right,
Christ on my left, Christ when I lie down, Christ when I sit down,
Christ when I arise, Christ in the heart of every man who thinks of me,
Christ in the mouth of everyone who speaks of me,
Christ in every eye that sees me, Christ in every ear that hears me.
