Today, Mary, today. I don't want evidence from the 2nd generation disciples, or even the 3rd, it is the 4th century and up, where we see the disintegration of orthodoxy in such an overt an undeniable manner. All the ecumenical councils, Tertullian, Augustine, Aquinas, Luther, Calvin, the papacy, transubstantiation/consubstantiation, Mariology, indulgences, inquisitions, crusades, ransom theory, satisfaction theory, penal substitution, Christus Victor, ....
The nonsense infiltrated the church right after day one, and has permeated almost its entire theology up to this day.
