"Some put on Christ as far as the receiving of the sacrament; others, as far as sanctification. The former, good and bad do equally; the latter, the good alone."
Calvin's Institutes: IV:19:16
This opposes the standard view that without faith the sacrament doesn't do anything - it doesn't "take." No, there is a union with, a putting on, Christ that happens in the sacraments. But without faith it does not benefit.
