The “Jesus never mentioned homosexuality” argument is meant to bully people into believing that Jesus actually took a benign attitude towards same-sex acts. Liberals reason that if Jesus disapproved of homosexuality, He would have said so. Moreover, He never mentioned gay sex, thus He didn’t condemn it.
Most people, including some Christians, don’t have a clue what Jesus did or did not say on any given subject, let alone what He thought about same-sex practices, so they fall for the “Jesus never mentioned homosexuality” lie, hook, line and sinker.
So, does Jesus approve of homosexual relationships?
At the very heart of the Christian view of God is the Holy Trinity. (This is not an essay on Christian doctrine, so bear with me for a moment.) Classical Christianity has believed that God exists in Holy Trinity, or tri-personality — the Father, Son, and Holy Spirit. The Trinity is not three gods in one. Each Person of the Trinity is fully God. They are one in essence with three separate and distinct personalities. All are infinite and eternal. Jesus Christ, the Son, is the Second person of the Trinity. The Son is in perfect union with the Father and the Holy Spirit. They are never, nor could they ever be out of union with one another. Jesus said, “I and the Father are one” (John 10:30). The deity of the Holy Spirit is also evident. In Acts 5:3-4 Peter told Ananias that by lying to the Holy Spirit, he had lied to God.
Following is one way of illustrating the Trinity:
“H2O…is common water-two parts hydrogen, one part oxygen. You can freeze H2O and you would have the solid, or ice. You can turn on your faucet and you would have the liquid H2O. You can hear the whistle of H2O that comes out of the tea kettle spout which is steam, but it would still be H2O. H2O can and does exist in solid, liquid and gas. The solid is not the liquid; the liquid is not the gas; and yet all three are of one nature: H2O. And that is exactly how it is with the Father, the Son and the Holy Spirit. The Father is not the Son, the Father is not the Holy Spirit, and Jesus is not the Holy Spirit.” (emphasis added – Source)
The crux of the matter is this: Those who try to make their case by arguing, “Jesus never mentioned homosexuality” are either ignorant of the doctrine of the Holy Trinity, or they ignore it for the purpose of supporting a hollow argument.
