D
He said “Well I still consider you a friend.”- which shows that his intention is not disrespect. The Calvinist didn’t have a clear understanding of scripture- that’s true. So you either see how he didn’t match what the Bible says, or you disagree with old hermit and say “Well I think he did match scripture and has a clear understanding.”
If someone said to you “God told Adam and Eve they would die if they ate the forbidden fruit, but they didn’t- therefore God lies.” It would not be disrespectful to reply “You are not understanding this clearly. Adam and Eve did die spiritually and immediately needed a Savior. They also died physically later on. God said they would die, but He didn’t say when. Therefore God is not a liar.”
When Jesus was asked if He was the Christ, the Son of the living God, He had no choice but to say yes. Not because He is bragging, but because it is the truth. And it is the truth that this Calvinist does not have a clear understanding of scripture- therefore you shouldn’t follow his teaching.
