God, who is love, calls all people to holiness. Christians are to bend their will to God's will, deny themselves and carry their cross, including those Christians who suffer from same-sex attraction, not affirm our fallen natures, and not to encourage others to do so, but to struggle to holiness with God's grace.
As a "Christian" who suffers from same sex attraction, the right "choice" is to carry your cross, deny yourself, and bend your will to God's will. The wrong "choice" is to wallow in our fallen nature and indulge in what the Bible calls an abomination and what the new testament and old testament and all the church fathers clearly condemned.
If your right hand, having no choice in being born with it, causes us to sin, what does Jesus tell us to do with it? He tells us to cut it off. Likewise with same sex attraction: struggle against it even if it hurts like cutting off your hand.
The cause of homosexual attraction, whether a psychological, social, hormonal, or spiritual, or even genetic is irrelevant to the fact that God says we are sinful and that homosexual activity is wrong. The cause does not justify indulging in the lifestyle or approving of it for the true Christian.
"You have not yet resisted to bloodshed, striving against sin" (Hebrews 12:4)
“See, you have been made well. Sin no more, lest a worse thing come upon you.” (John 5:14).
“Neither do I condemn you; go and sin no more.” (John 8:11)
We are all infected with sin- physical, emotional, and spiritual- diseases because of our fallen natures. But in Christ, in our our baptism in Him, we are on our way to get rid of all of that because He took our nature and perfected it in Himself.
Orthodox Christianity teaches that homosexual sexual activity- indeed any such activity outside the Sacrament of Holy Matrimony between one man and one woman- is immoral.
But those afflicted with the psycho-social illness of same sex attraction who also wish to live a holy Christian life should be loved and told the truth about this lifestyle.
Those who do not want to live a holy Christian life should be loved nonetheless but a Christian who disagrees with their lifestyle need not be called a bigot or homophobic.
