Forgive me, Iaimisry, but I don't know how to use the quotations.
There are studies that suggest that homosexuality is a mixture of 'nature' and 'nurture'. 'Nurture' doesn't necessarily mean 'choice' either. While there is nothing definitive, it is strongly suggested that there is no one single etiology, which would make the curing of homosexual attraction very difficult. Also, based upon my discussions with Christians who have a primarily emotional and sexual attraction to members of the same-sex, I do believe them when they say that have not chosen to have these attractions. I mean why would someone choose to be homosexual and then rush to reparative therapy. If homosexuality is indeed chosen, reparative therapy is unnecessary.
The APA doesn't believe there is anything to cure. This shouldn't surprise you since it is a secular organization. But besides that, I'm not sure what there is anything to cure either. What is there to cure? I have agreed that homosexual acts are incompatible with the Faith. I just don't see what secular psychology has to offer someone that is suffering from a spiritual ailment. Isn't that what our spiritual fathers are for? Should we expect secular institutions to cure spiritual ailments? Even if they tried, they couldn't. Only God provides healing.
You make an interesting point about the difficulty of the cross of same-sex attraction and the gift of celibacy. I firmly believe that the Lord does not give people more than they can handle. I believe that those with homosexual orientations can bear that Cross, while not having the gift of celibacy. I'd say the same thing to a heterosexual man or woman who spent their lives looking for a spouse and never finding one.
I believe that those with same-sex attraction carry a large cross and that is why I am quick to come to their defense. A lot of homosexuals, especially in the Protestant environment I grew up in were told, "Become straight or you're not welcome here." We see homosexuals becoming resentful and abandoning the Church and going and living lives outside the will of God because many attempt to become heterosexual and they cannot. We really must support those who suffer with this great burden. We shouldn't look down on them or think of them any differently than anyone else. Since they cannot have their own families, we need to welcome them into ours and help them have a sense of community. C'mon, we all have been to Orthodox parishes where there is that effeminate guy in Church and everyone looks at him like he is an exhibit from the zoo. How horrible that must feel for those people. How alienating and lonesome such an experience must be. No, we should support them in their struggles-it's the Christian thing to do, IMHO.
