Lately I’ve been interacting with a number of people who call themselves “moderate Calvinists”. I’ll be honest, it has been frustrating (for both sides, I’m sure). One reason is a body of literature they have read, that I haven’t, and they point to as authoritative. They usually despise John Owen, and (from my perspective) take comments by scholars (Owen and otherwise) out of context for their arguments.

Moses Amyraut- the original 4-Pointer
They hold to a “hypothetical atonement” instead of a particular atonement. They are similar to the Amyraldian position (they resist this label) in that the atonement is universal in extent, even if only efficient for the elect. They recognize the reality of the elect. So they’ve got that going for them.
One claim I’ve heard from them is that the Canons of Dort do not support the doctrine of limited or particular atonement as espoused by 5-Point Calvinists. (If I’ve misunderstood in the flood of verbiage, I’ll recant.) They see the 5-Points as a modern formulation (yeah, so?), that has no basis in the work of Calvin and the Canons. I thought I’d look at the Canons (it has been awhile) and see what I find. It is kind of hard to re-read all of Calvin on this topic.
