The question isn't dependent upon "what works for heterosexuals will work for homosexuals" or any sort of parallel consideration here between these two issues, BUT it IS about the disorded thinking that homosexuality represents.
And the dishonesty involved in those who "hide" their homosexuality inorder to gain entry to the seminaries and the priesthood later, in defiance of all that is holy about the vows they allegedly swear to respect (but do not given the persistence of their affiliations).
The key "proof" here is confession. A person who does not confess homosexuality is hiding something significant as to their character, morality and religious state. It may be fine socially in some contemporary societies and cultures to do so (as in, "who's business is it," or even, "it's fine, do what you want"), BUT, in relationship to the Priesthood, it's a defiance of trust, a serious moral failing to attempt to manipulate vows (and scripture itself) inorder to self satisfy.
The question I'd have is why would anyone who was homosexual want to be in the Priesthood? What's the motivation?
A person who does not confess homosexual acts is hiding something significant. Homosexual orientation, in and of itself, is not sinful and does not have to be "confessed."
The question I'd have is why would anyone who was homosexual want to be in the Priesthood? What's the motivation?
Given the number of suspected homosexuals in the priesthood now, and in the past, it is very possible that they have been called to the priesthood.
You are likely to be somewhat disappointed in the upcoming document. There are reliable indications that not all homosexuals will be barred from seminaries. Those with less than three years of celibacy, those who participate in openly gay activities, and those who are "irrevocably committed" to a homosexual lifestyle, will not be permitted.
A long-time celibate homosexual, however, will likely be admitted and, if deemed satisfactory, will be ordained.
The question is, how does one bar a homosexual from the seminary if he is celibate and is determined to keep his orientation to himself?
There is no "test" for homosexuality.
