And EVERYTHING in those 'creeds' are found in the Scriptures.
No 'traditions' need apply.

Well, not 100% in agreement, the entire reason for the Creeds was because there were divergent interpretations about Scripture. Tradition, i.e. what was handed on through the Church did play a role in how said scriptures were interpreted, i.e. Patristic writings and how the Church prayed in Liturgy, etc.
