ChurchMilitant-TV : NOT Born That Way
The truth needs to be said, because the lie is too destructive.
April 27, 2016
Some might perhaps be actually born that way, due to hormonal dysfunction due to stress during certain parts of pregnancy.
But even they do not have a genome pointing to sodomy or lesbian acts.
Even in that case, human evil choices are behind homosexuality, namely whoever put too much stress on the mother. The verdict of St Paul that desires against nature come from idolatry is not overturned. If certain ways of becoming homosexual are by the persons own idolatry, either of "rolemodels" of his own sex (in that case perhaps not sufficiently integrated) or of a sect that humbles the human nature, as in the case of Oscar Wilde being a freemason (he was buried masonically, so it is a fair guess), other ways affecting people earlier are from someone else's idolatrous choice.
But whether one is "that way" or not is not a measure on whether one cannot or can marry, usually. An unfortunate perverted desire for one's own sex does not absolutely preclude a natural desire for the opposite.
God predestines no one to evil:
We not only do not believe that any are foreordained to evil by the power of God, but even state with utter abhorrence that if there are those who want to believe so evil a thing, they are anathema.
Council of Orange (529 AD)*
God may predestine someone to chastity, even against his will, like by denying the normal function of genitals, but this is generally not the case with homosexuals. God is not predestining them to a situation in which they are both unable to be chaste and unable to marry, as other men and women. This means that the presence of a known homosexual predesposition is not an impediment to marrying someone of the opposite sex.
And this means sth about the pastoral which has on one hand brought some to fifteen years of therapy and on the other brings certain homosexuals in Paris to continuing their evil ways "because they have a right to be loved and to love" - indeed they do, they do have a right to turn back from their bad ways and to do the normal thing.
This also means, precisely as Voris implies, those who do not do so, do not have the excuse of saying "that's how God made me". No, you or some other men did so, not God.
