I recently enjoyed a week of meetings taken by an ex-Calvinist who had been Reformed for 25 years. He left that movement because his own repeated reading of scripture was clashing with his systematic theology, and the cognitive dissonance eventually forced him to change his thinking. It was a terrific week. He is a gracious man by nature, but extremely thorough in his presentation and utterly convincing.
Not that I needed convincing on that subject …
Predetermined?
One of the points he made in the course of the week is that Calvinists often tell us determinism was the teaching of the early church, or at very least that Calvinism is consistent with the teaching of the church fathers. After all, or so they reason, the Bible teaches these things, therefore the fathers must have believed them.
