September 14 is the Feast of the Exaltation of the Cross, celebrated  in both the Eastern and Western Churches. This day is linked to Constantine the Great and to his mother Helena, who has traditionally been associated with the findings of the True Cross and the Holy Places in Jerusalem.  Constantine is further linked to the Nicene Creed, the results of his efforts to unify the church in the face of the Arian heresy.  I have previously commented on the Nicene Creed, but  I was once again meditating on the Creed and my fascination with Constantine as a historical figure,  so I would like to add some additional notes to my previous article. In the future I will combine and edit the two articles.  The Creed used here is the one used by the Byzantine Catholic Church in the United States. 
I believe in one God, the Father Almighty, Creator of heaven and earth, of all things visible and invisible: and in one  Lord Jesus Christ, Son of God, the only begotten  born of the Father before all ages, Light from light, true God from true God, begotten, not made, one in essence with the Father; through whom all things were made. For us and for our salvation, he came down from heaven and was incarnate from the Holy Spirit and the Virgin Mary and  he became  man.  He was crucified for us under Pontius Pilate and suffered and was buried. He rose on the third day according to the scriptures. He ascended  into heaven and is seated at the right hand of the Father, and He is coming again in glory to judge the living and the dead, and His kingdom will have no end. And in the Holy Spirit, the Lord, the Creator of Life who proceeds from the Father. Together with the Father and the Son He is worshiped and glorified; He spoke through the prophets. In one, holy, Catholic and apostolic Church. I profess one baptism  for the remission of sins. I expect the resurrection of the dead  and the life of the world to come, Amen.
