I know “gay” is a tricky word on CAF, but I use it as most people my age generaly use it: having (exclusive or dominant) same-sex attraction. So that first.
I just had a thought I’ve never considered before. It would be one thing, perhaps more easily understood, to say that those who are not attracted to members of the opposite sex just ought not get married. Marriage is no requirement - certainly no requirement for happiness or even ultimate fulfillment in Heaven. So no real loss there! If there is no desire for that kind of relationship with the opposite sex, there is no real harm.
However, with the case of homosexual persons, it’s not just a lack of attraction or ability to relate in certain ways to the opposite sex. It’s that; but it is, additionally, the deep desires and wishes to be in relationship with someone of the same sex. In other words, the same attractions, desires, and human feelings for a relationship are present for a gay person. Just not the right person… In the view of the Catholic Church.
This way of thinking makes me wonder more as to what God’s plan is for the gay person. For, to restate quickly, the gay person does not only have a lack of desire and feelings to marry someone (of the opposite sex). They have, in addition, the added state of desiring and wanting to be in union with someone of the same sex.
