1) Paul is not God.
2) When Paul is citing this list of sins he is doing it to make the point that the Church in Corinth is free of these sins, which were listed in the Torah, because of their faith in Jesus. Paul's letter to the Romans spells out in excruciating detail how the law no longer applies to Christians because they have died to sin and been risen in Jesus. In other words, these categories were good enough for our Hebrew forebears as they went, but as Jesus says to the tricky scribes, Moses gave those laws (specifically speaking of divorce) because the people's hearts were hard. Jesus clearly demands a higher mode of ethical conduct; in repeated instruction and parables he contrasts what people were taught with what he says. Therefore, Paul's personal feelings about what kind of people will inherit the kingdom of God, taken as a blanket condemnation of certain behaviors, is not only contrary to Paul's own teachings on the matter of justification, but deeply opposed to the spirit and teaching of Christ.
3) What Paul is giving a list of, in both verses that you cite, are examples of depraved conduct, as he sees it. His point is that when people turn their backs on God, they are prone to act in all kinds of sick ways; his point is not to list things that Christians should mark in their notebooks as being the "newly revised Levitical code". Paul is saying, "You guys used to do all kinds of crazy ****, but now that you have Jesus, you've got your act together." I would say that there is a big difference between lustful, furtive couplings and a committed, healthy relationship. The notion of a committed, healthy homosexual relationship was utterly foreign to early Jews and Christians, as was the notion of abolition [of slavery], racial intermarriage, antiseptics, and all sorts of other things that we take for granted today.
4) Jesus never mentions homosexuality in the Gospels, not once. If it was so important that we had to clamp down on it anywhere and everywhere it rears its terrible head, don't you think he would have at least, you know, brought it up? There is on the other hand, a specific condemnation of divorce in the Gospels, spoken by Jesus, and yet I don't hear Focus on the Family saying anything about divorce.[/size]
