It’s illogical because the absence of condemnation doesn’t equal support. Just because we don’t see Jesus mentioning homosexuality by name in the Gospels—just as we don’t see him mentioning, say, sex trafficking or torturing animals—doesn’t mean he supports it. It misrepresents Jesus because He is God. Therefore, whatever God says in the Old or New Testament, Jesus says also. Jesus’s words aren’t limited to what we read in Matthew, Mark, Luke, and John. The entire biblical canon is His, and it’s all authoritative and without error (2 Tim. 3:16–17).
