You often hear the odd remark that Jesus never condemned homosexuality. This is rather strange for many reasons. For one, what people really mean by this is that Jesus in the Gospels never condemns it (supposedly); but the Gospels don't tell us everything Jesus had to say on every subject. It's not like they're a list of what He thought was right and wrong. They're presentations of Christ's teaching concerning salvation in regard to His work and our trusting in Him as Lord. He doesn't explicitly condemn pedaphilia or worshiping Zeus in the Gospels either. That has nothing to do with whether He implicitly condemns them both through general condemnations of the sinful categories under which they fall and by way of affirming the rest of the Bible. The Gospels, however, do give us a representative example of what He confirmed and condemned, and this is why we know what He believed on the matter. So here are the top 5 reasons we know that Jesus condemned and condemns homosexuality.
1. Jesus is YHWH God, who is the same yesterday, today and forever. And YHWH God condemned homosexuality in Leviticus 18:22. Hence, Jesus, who as God does not change, condemned and condemns homosexuality.
2. Jesus affirmed the inspiration and infallibility of Scripture (it cannot be broken), and thus affirmed that what it says in terms of moral issues is absolute and rather than be diminished to specifics, should be expanded upon to include a rejection of all aspects of the evil against which the Old Testament speaks and a much fuller embrace of the good in all of its applications. Hence, Jesus would not, nor does, do away with the command that condemns homosexuality.
3. The word porneia in Second Temple Judaism referred to all forms of sexual immorality that included homosexuality. When Jesus condemns porneia as evil, He condemns homosexuality with it.
4. The apostles continue to speak for Christ, as Jesus reveals to them His teaching and His Holy Spirit guides them to write what He wishes to teach that becomes the New Testament. Hence, what is found in the rest of the New Testament as condemnations of homosexuality are condemnations made by Jesus.
5. Jesus confirms the Genesis narratives in terms of their teaching that God intended one woman and one man to come together as one, and that this is the only model we have affirmed by Him. Furthermore, a confirmation of the Genesis narrative is a confirmation of the larger teaching of Genesis that condemns all non-procreative, and therefore chaotic toward human life and existence, sexual acts, which would then include a condemnation of homosexuality.
So the next time you hear that Jesus never condemned homosexuality, you should be able to assess the superficiality of that comment. One may enter a debate concerning the specific passages, but it is clear that as Creator, Jesus would not have run counter to the idea that sexual acts that do not work toward allowing God to create human life through them by obeying the command to become one in the male-female union are evil, as the rest of the Bible indicates.
The good news is that if one humbles him or herself and allows God to correct him or her, forgiveness and life can be found in the Lord Jesus Christ. If we obey His words, "Repent and believe the good news," we can enter a salvific relationship with God whereby we will no longer receive any condemnation, but begin a journey toward holiness in the Lord.
