I'm not a Jew; so I'm ok to eat pork!
It certainly does come down to Biblical interpretation. Through a proper understanding of the Bible we get a picture of who God is; above all He is Holy, Holy, Holy.
1 Corinthians 6:9-11 is one of the clearest verses in the Bible in regards to this issue...
'9 Or do you not know that wrongdoers will not inherit the kingdom of God? Do not be deceived: Neither the sexually immoral nor idolaters nor adulterers nor men who have sex with men[a] 10 nor thieves nor the greedy nor drunkards nor slanderers nor swindlers will inherit the kingdom of God. 11 And that is what some of you were. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God.'
The Christian has been washed clean. They are a new creation. So it is not possible for a true believer to continue in a homosexual relationship if they have been washed clean. Im not saying that desire or attraction goes away, but to blatantly continue in sinful behaviour is not sanctified behaviour. Same sex relationships have no place in the Kingdom of God. (Not my words, but God's)
