It is worth noting that the "essentials" of the faith continued growing throughout the centuries. Paul's simple statement of belief was this:
"Christ died for our sins according to the Scriptures, and that He was buried, and that He was raised on the third day according to the Scriptures." (1 Cor. 15:3-4)
27 words!
Tertullian's simple statement of belief was this:
"To believe in only one God Almighty, the Creator of the universe, and His Son Christ Jesus, born of the virgin Mary, crucified under Pontius Pilate, raised again the third day from the dead, received in the heavens, sitting now at the right hand of the Father, destined to come to judge the living and the dead through the resurrection of the flesh."
63 words!
Compare these to the 12,079 words of the Westminster Confession of Faith!!! Saying nothing, of course, of the Heidelberg Confession, the Articles of Faith, the Baptist Confession, etc., etc., etc.
Creeds, Confessions, Constitutions, Statements of Faith, etc., were not of grave importance to the early Christians. The essentials of the faith made in statement were always very brief (less than 100 words). If you want to know what was of grave importance to the early Christians, you can read Paul's declaration concerning sound doctrine. You can also look up everything they said about good deeds in both the New Testament Scriptures as well as the first 300 years of Christianity. The kind of fruit you produced was of the utmost importance compared to the "essentials" that you believed. Yahweh God is far more concerned with your obedience and the fruit you produce than with your particular theological dogma. Remember that.
