It seems like this would be a simple issue for an Orthodox Christian:
Holy Scripture is not ambiguous about the morality of sexual relationships outside of marriage between a man and a woman.
Holy Tradition is not ambiguous about the morality of sexual relationships outside of marriage between a man and a woman.
The Church is not ambiguous about the morality of sexual relationships outside of marriage between a man and a woman.
Agreeing with these teachings makes one a faithful disciple of Christ, the Church, Scripture and Tradition; disagreement places one's opinions outside of Christ the Church, Scripture and Tradition.
I understand when someone outside of the Christianity does not agree with the sources of teaching authority within the Faith but it is strange when Christians allow emotion to form their opinions to the point they no longer accept or understand even the ABC's of Christian moral teaching on sexuality.
As believers we are to renew our minds by allowing our opinions to be formed by the Christian revelation rather than by popular culture and feelings, are we not?
The thing is, we betray Christian revelation for the sake of the popular culture every single day and hour and minute of our lives. We use credit cards. That's partaking in usury. Usury is forbidden by Scripture. There is no way around it.
Our clergy thus betrays Christian revelation all the time. And the same clergy tells us, look, the Church in Her infinite wisdom decided that gay sex is bad.
I am not saying that the Church is not wise. I am not, actually, saying that She should reconsider our views on usury - but I cannot say I don't hope She will (absolutely unrealistic as it is). I hate usury and I hate myself for partaking in it.
But, similarly, I hate myself for yielding to the view that whatever the Church says right now is the ultimate truth. I know I should not yield to this view, with all my respect and adoration due to the Church. The thing is, I, too, am the Church. And I know that there is absolutely nothing wrong with homosexuality (unlike usury, which is really bad and harmful and sinful, in my humble opinion) and that homosexuals, just like heterosexuals, or paraphiliacs, can marry and have a great life, and theosis, in the context of THEIR monogamous, committed, lifelong marriage. Usury was held unanimously as a sinful practice for quite some time by the Church (I'd say, rightly), but now no one even recalls it. Homosexual marriage is held as impossible and sinful for quite some time, to (in my humle opinion, UNrightly), - so maybe in time it will not be something that people will even recall, just like no one recalls right now how fircely the Church opposed usury?
