Cyril of Jerusalem
Patristic
A.D. 313–386
“These articles of our faith were not composed out of human opinion but are the principal points collected out of the whole of Scripture to complete a single doctrinal formulation of the faith. And in like manner as the mustard seed contains numbers of branches-to-be within its tiny grain, so also this creed embraces in a few phrases all the religious knowledge contained in the Old and New Testaments together. Look now, brethren, and "hold the traditions," which are now being imparted to you, and "write them on the table of your hearts."”
