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.
And there still IS!
I'd always heard that the 'creeds' distill the Scriptures down into the ESSENTIALness of Christianity.
IE this is the important stuff.
The rest can be taken or left.
