A theological system that takes God's New Covenant people back to a temple, an altar, a priesthood, andsacrifices of the Old Covenant is a system which detracts from the perfection, completion, and sufficiency ofChrist's atonement. It's a system that takes Christ's Church back to its infancy (Galatians 4), to a church justlearning its ABCs, to a "church under age" (Westminster Confession of Faith 19:3).
