Creed based on the synoptic gospels

At the Council of Nicaea (in 325) a creed was written that used philosophical language and argument that is related to the prologue of John and a few lines from St. Paul. The Synoptic Gospels and much of the work of the apostles are not used in the creed. Write a creed based on the synoptic gospels. How would this creed have changed Christology? Would Christianity be significantly changed? How so or why not?
