To a certain extent he’s correct. The temptation to engage in homosexuality is not purely a matter of choice. Temptation can be managed and even redirected in Christian ways, but that usually takes faith, time, and discipline. In other words, I can’t entirely control it if I’m attracted to a pretty woman who is not my wife.
Fortunately, temptation is not sin. What is a matter of choice is how I react to the temptation. If I choose to act on it or even wish I could act on it, that’s sinning. Sometimes I wish I could turn off temptation—it’s annoying—but I know God will not allow me to be tempted beyond what I can resist. He’s promised that.
As for bringing homosexuals into the church, I see nothing wrong with it so long as they’re repentant. However, I believe homosexuality is a disorder so pernicious I would be very, very hesitant to put even repentant homosexuals in leadership positions. That’s not incompatible with scripture, because scriptural says only the best of the best should be given such leadership roles in the church.
I agree with you. Homosexuality is one of many manifestations of sin, and it is not the most grievous sin. However, it is a sin that some have to bear. I have no problem with a Christian with homosexual temptations, as long as those temptations are not acted upon, just like any other sin.
