The Word fornication appears in both Testaments quite often - which underlines the importance to resist these sins.
It’s in quite a few verses explained what’s meant. I think, it’s clearest in Paul’s letter 1Cor 6,16-12:
16 Do you not know that he who joins himself to a prostitute becomes one body with her? For, as it is written, “The two shall become one.” 17 But he who is united to the Lord becomes one spirit with him. 18 Shun immorality. Every other sin which a man commits is outside the body; but the immoral man sins against his own body. 19 Do you not know that your body is a temple of the Holy Spirit within you, which you have from God? You are not your own; 20 you were bought with a price. So glorify God in your body.
As far as homosexuality is named, Paul accused sinners of fornication, namely in 1Cor 6,9: Do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived; neither the immoral, nor idolaters, nor adulterers, nor homosexuals - and in my bible; pedophiliac is named too!
And here we this month in another forum had a monk posting; that even opening of suchlike pages in the net fulfills that sin, for every click on such pages supports the execution of that sin; - “others then do it for us, but it’s us who becomes guilty”.
But even before that - in 1Cor 5,1 Paul names explicitly fornication by his word: It is actually reported that there is immorality among you, and of a kind that is not found even among pagans; for a man is living with his father’s wife. 2 And you are arrogant! Ought you not rather to mourn? Let him who has done this be removed from among you. 3 For though absent in body I am present in spirit, and as if present, I have already pronounced judgment 4 in the name of the Lord Jesus on the man who has done such a thing. When you are assembled, and my spirit is present, with the power of our Lord Jesus, 5 you are to deliver this man to Satan for the destruction of the flesh, that his spirit may be saved in the day of the Lord Jesus.
Paul in all points referred here on: Lev 18,7 et seq. - 20,11 - Dtn 27,20. All trespassers where stiffly prosecuted not only in Moses age 1,250 before Christ, but in Roman Law of Jesus’ time as well. It’s not only Sodom and Gomorrah who here destroyed for it’s vie, but several high cultures too where - one of it was the Roman Empire.
But howsoever:
Every created human received with his conception God’s manual - named “Conscience”. So everybody does know what’s right and what’s wrong. He who doesn’t put that manual away. Lost is deliberately.
