Responding to those who say that the Lord didn’t condemn homosexuality and therefore it’s okay:
Jesus didn’t specifically condemn a lot of things that we know are wrong (such as slavery). This silence tells us almost nothing.
He didn’t have to say anything. In contrast to pagan Rome, there was no debate about it in first-century Judaism. The Old Testament teaching on the subject was clear. By saying nothing, He let the teaching stand.
If He had wanted to overturn Scripture’s clear and consistent teaching on homosexuality (or wildly wrong interpretations of the OT), He had every opportunity to do so (“You have heard that it was said…. but I say to you….”).
While Jesus was compassionate with those who didn’t live out the biblical ideal (John 7), He defined marriage as between a man and a woman. Any other sexual union by definition would be adultery or fornication and thus out of bounds.
There are serious and legitimate disagreements about what the Lord meant about this or that and what it means for His people today. This subject isn’t one of them.
