Preaching Christ from the Old Testament . . . Before the New Calvinism

A good piece from an Old Calvinist on Cain building the first city in Genesis 4:

But they who are moved by this consideration [who exactly lived in the first city] forget to take into account that the writer of the sacred history does not necessarily mention all the men who might be alive at that time, but those only whom the scope of his work required him to name.  The design of that writer (who in this matter was the instrument of the Holy Ghost) was to descend to Abraham through the successions of ascertained generations propagated from one man, and then to pass to Abraham's seed to the people of God, in whom, separated as they were from other nations, was prefigured and predicted all that relates to the city whose reign is eternal, and to its king and founder Christ, which things were foreseen in the Spirit as destined to come. . . . (City of God, 15.8.)

Augustine wasn't just about allegory.
