Tertullian wrote about the “Rule of Faith” in the second century:
To believe in only one God Almighty, the Creator of the universe, and His son Jesus Christ, 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 riht hand of the Father, destined to come to judge the living and the dead through the resurrection of the flesh
This statement that Tertullian made, only one generation after the apostles, contains only 63 words. This is a very simple statement. The Westminster Confession of Faith, promulgated by the Puritans in the seventeenth century contains 12079 words.
Somehow the essentials of faith kept growing through the centuries. (Found in “Will the Theologians please sit down” from David Bercot).
This “Doctrianity” is spreading like a disease. This comes through eating from the forbidden tree.
