So I was struck by the following quote in Calvin on the sacraments, "we must utterly reject that Scholastic dogma … which notes such a great difference between the sacraments of the old and new, as if the former only foreshadowed God's grace but the latter give it as a present reality" (Inst VI.xiv.23). (The word translated 'foreshadow' is "adumbrarint" which can mean outline, but can have the connotation of "screen" or even "obscure", and it has that kind of sense here.) Calvin goes on to make his point from the opening verses of 1 Cor 10, arguing that Paul's point there is based on equality of the Jewish and Christian experience of the sacraments.
The quote struck me because what Calvin calls a "Scholastic dogma" is a very common view in evangelical circles. So often the only relationships between the OT and NT are promise-fulfillment and a relationship of contrast. Calvin reminds us that there is another relationship of continuity. The book of Hebrews illustrates each of these relationships (see Heb 4:1; 11:40; 12:18-29).
