This article addresses the issue of why God would sanction, via the Old Testament Law, less than ideal practices such as slavery, polygamy, and excessively harsh punishments for certain crimes. I appeal to two concepts (the idea of a supererogatory good, and the idea of Molinism) to explain why God sanctioned these practices. I explain that God’s sanctioning these practices may have been necessary in order to create the world with the most possible good.
