I agree completely, with one change We are not called to be like Christ, but to become like Christ.
This side of death (or the Rapture) we still have our Sin Nature to deal with and we cannot be perfect. Still. we should strive as much as possible, relying on God's grace and on promises like 1 Cor 10:13. There is no excuse not to strive.
The Law exists for two purposes: to teach us virtue and character, and to teach us the need for God's grace.
When we have learned those lessons, we have "graduated." We have learned the virtues that we need to resist the vices, which are our Sin Nature. Paul calls these virtues "the fruit of the Spirit." And we have accepted through God's grace, additional spiritual virtues -- virtues which we cannot learn or earn on our own -- that we need to not just resist, but to overcome the vices. Paul calls these unearned virtues the Armor of God.
When we "graduate," we are no longer under the law, but that does not mean we are free to indulge our vices, our old Sin Nature. It means that we are to obey our higher nature, the new nature growing within us due to the fruit of the Spirit and the Armor of God.
What I get out of this paragraph is that you are (again) claiming that Levitius 20:13 is not part of the Holiness Code.
I realize that we are not going to agree on whether Leviticus 20:13 is part of the Holiness Code or part of the moral code. I agree that many things that are associated with homosexual practices are immoral. They are immoral when they are associated with heterosexual practices also. Adultery, fornication, incest and "fertility rites." Also rape, child molestation etc. But these practices are not a part of homosexual love any more than they are a part of heterosexual love.
Neither is there any evidence that homosexuality is condemned as a moral sin. It is prohibited by the Holiness Code, but the Holiness Code has fulfilled its purpose and is no longer binding.
There is no evidence in Scripture to support your claim, either. And there are many who do see evidence of the Bible condoning committed same-sex relationships. These people cite David and Jonathan, Ruth and Naomi, Elijah and Elisha, and Jehu and Jehonadab. Personally, I am not certain how much the "queer reading" is not reading more than is there. But it does leave open enough doubt in my mind that I can't say that there is absolutely no acceptance of homosexual relationships.
