If he was a 4 pointer then he did not hold to the DoG.
Question remains IF Calvin himself held though to "4 or 5 points". as he did write in his view that Jesus death as the atonement was indeed propiation/able to pay for all sins of whole world, but effectionally applied only those those whow ere elected on by God to receive Christ...
Think IF phrased that way, most 4 pointers like myself are 5 pointers!
