OK, I’m serious about this. I’m not even being snarky. Really.

If you are one who thinks that homosexual sex is sinful, can you please explain to me WHY a gay or lesbian person who is in a long-term, monogamous relationship would not be able to wholeheartedly follow Christ?

My only stipulation is this: You may not quote one of the six verses in scripture that mentions homosexuality.  Instead, you must use theological and/or philosophical arguments to attempt to convince me that when you have genital contact with someone of your own gender, it somehow inhibits your relationship with Christ.

Thank you in advance for your civility in answering this question.
