I will say, though, that I believe when considering from a Christian point of view, we need only consider the New Testament, because when Jesus died, the laws given by God to the Israelites were no longer valid, so we don't need to adhere to Old Testament laws these days. Much the same as how Christians can now get tattoos, eat pork, and wear clothing made from more than one material! So the verses on homosexuality that personally made me change were:
"Or do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived: neither the sexually immoral, nor idolaters, nor adulterers, nor men who practice homosexuality, nor thieves, nor the greedy, nor drunkards, nor revilers, nor swindlers will inherit the kingdom of God."
1 Corinthians 6:9-10
"We also know that the law is made not for the righteous but for lawbreakers and rebels, the ungodly and sinful, the unholy and irreligious, for those who kill their fathers or mothers, for murderers, 10 for the sexually immoral, for those practicing homosexuality, for slave traders and liars and perjurers—and for whatever else is contrary to the sound doctrine."
1 Timothy 9-10
"Because of this, God gave them over to shameful lusts. Even their women exchanged natural sexual relations for unnatural ones. 27 In the same way the men also abandoned natural relations with women and were inflamed with lust for one another. Men committed shameful acts with other men, and received in themselves the due penalty for their error."
Romans 1:26-27
I also want to say that I find the church in the UK is much more lenient about homosexuality than in other countries. My husband is from country B, and we live in country C (neither the UK). I think British churches are very affected by British culture when it comes to things like this, whereas the other churches we go to seem to stick purely to the bible when forming their beliefs and teachings. So I think this is why British churches either don't speak about homosexuality at all, or say it's okay. Cultural differences.
