Which of the five points of Calvinism have you found non-Calvinists understand the least or react the worst to? I have issues with all of them but limited atonement is the only one that actually pisses me off.
I have no major problems with Limited Atonement, but that's because I view the gospels through a universalist lens. I believe all can find their way to the Divine, but only those whose path goes through Christ will be drawn to him. My objection with Calvinism lies more with the combination of Unconditional Election and Irresistible Grace. If God's grace is indeed irresistible then how then did either Lucifer or Adam fall? If it is irresistible, why then does God Elect some to Damnation?
