Matthew 5:28
1 Corinthians 6:9
Do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived. Neither fornicators, nor idolaters, nor adulterers, nor homosexuals, nor sodomites,
Just a moment there! It seems to me that your bible might not be up to snuff in its translations. As a Classics student, I know it is difficult to convey all the different meanings of a word without a direct equivalent in english. Homosexuals nor sodomites, however, does not capture any of the greek words' meaning. homosexuals, as you render it, actually refers specifically to boy prostitutes. Sodomites, likewise, specifically refers to men who use such prostitutes. It is in paralell with his other prohibitions on material immorality (you leave out the next verse on theives and the greedy) and the meaning can be cross referenced with several other Pauline passages. Now buying a little boy prostitute is a bit different from homosexuality, don't you think?
Also I'd warrant that rape, for instance, is a worse sexual immorality than sodomy.
