On social media I am constantly told that Our Lord would have no problem with so-called “same-sex marriage.” After all, the gospels do not report Jesus directly condemning homosexual acts. However,to argue on this basis that He approved of sodomy is defective reasoning. Stating that “Jesus is not against it so he must be for it” bases its conclusion on a supposed lack of evidence to the contrary, instead of on the existence of any indication one way or the other. Lack of evidence proves nothing.
Because the gospels do not have a record of Jesus doing something does not mean that he did not do it. It is most likely the evangelists did not record it; as is well known, the gospels do not contain everything Jesus taught and did, as St. John states in Jn 21:25: “But there are also many other things which Jesus did; were every one of them to be written, I suppose that the world itself could not contain the books that would be written”. Remember too that almost nothing is said about Jesus’ early years in Nazareth, and even a large part of his public life is not told.
In fact, it is reasonable to say that Christ did directly condemn homosexual acts, because homosexual acts were condemned in the Old Testament before Jesus as well as in St. Paul’s Epistles after Him. In his letter to the Galatians, Paul reminds us where he got his teaching (Gal 1:11-12):
“For I would have you know, brethren, that the gospel which was preached by me is not man's gospel. For I did not receive it from man, nor was I taught it, but it came through a revelation of Jesus Christ”.
Furthermore, Jesus assured his apostles that the Holy Spirit would “bring to your remembrance all that I have said to you” (John 14:26).
St. Paul certainly shared in this assurance. This being the case, his teaching on homosexuality may very well be what he remembered Jesus saying to him in a revelation.
Additionally, when Jesus sent out representatives he told them, "He who hears you hears me, and he who rejects you rejects me, and he who rejects me rejects him who sent me" (Luke 10:16). So—since Paul was sent by Jesus, when we “hear” him in his epistles, we hear Jesus. There really is no doubt that Jesus condemned homosexual acts as sinful, so do not be hoodwinked by the defective reasoning of those who would undermine marriage.
