In working on the most recent issue of Christian History & Biography ("Debating Jesus' Divinity"), we once again ran into the old canard that the Nicene bishops relied more on Greek philosophical concepts than on the Bible. That is the conventional wisdom in some circles, but let's take a closer look at what those bishops did. With the help of Norwegian church historian Oscar Skarsaune and his book In the Shadow of the Temple: Jewish influences on Early Christianity (IVP, 2002), we'll learn a different story.
Let's begin at the beginning. The oldest creeds were simple baptismal vowsaffirmations of belief in God the Father, in Jesus the Messiah, his Son, and in the Holy Spirit. Hints of such early baptismal statements can be found in Justin (writing about 150) and Tertullian (writing between 190 and 200).
By about 220, baptismal candidates were affirming a slightly more complex set of beliefs. Here is how the Roman presbyter Hippolytus describes the questions they were asked:
Do you believe in God the Father Almighty?
Do you believe in the Messiah (Christus) Jesus, the Son of God,

If you translate those "Do you believe" questions into "I believe" statements, you have something very much like the Old Roman Creed which took final form in the Apostles' Creed (5th century).
