Prisca Theologica

This may be true [that there is an ancient theology], but we don't know it without a teacher. And that's why Christ is Rabbi. Christ leads you to that universal theology, and then gives the solution to it. Which is His bodily death and resurrection. As, you see with Natural Religion, moral truths are objective, and since they're objective, they require divine punishment and reward. And since no man is righteous enough for a reward, and all must be punished, God came down to Earth as a Man, and lived a perfect life with no Sin. And then He demonstrated to us through His life and teachings, the way we ought to follow, showing us how far we lack, but also giving us the final proof of that objective moral standard. So, that's why Christ is Rabbi. And He died, and substituted our sin with His righteousness, and gave us His righteousness, and died and was buried with our sin. And then He raised, which cleansed us, as our sin was dead with Him.

Also, Moses was revealed this Prisca Theologica in the Exodus of divine punishment and reward, while Christ satisfied it in His life and ministry. Showing, that God must reveal Himself if He is truly God. And He did three times, with the Deluge, the Exodus and His Life and Teachings, and Bodily resurrection.
