Not quite sure where you're going with this. I think the point was that homosexuality (same- sex) and heterosexuality (male - female) is only blessed between a man and a woman in a loyal committed loving relationship. Even the Catholic Church, from what I hear, when they consider divorce and annulment, take into consideration if a marriage is founded on true love, in a peaceful loving relationship. A legal marriage, which can only happen between a man and woman, (even if there is a church marriage it may not be what they call a sacramental marriage), a legal marriage only marries a man and lady before a court or court authority. But to be a real marriage before the church, the marriage must be made real by a loving relationship. Day by day.
I'm not Catholic, but my home church is a traditional liturgical church. But, from what I understand, that church will honor a court marriage, or an informal, loving relationship between a man and a woman, if a couple are married by love. It's God's love that marries people, but the legal court papers are a sign and public witness that confirms the relationship.
From what I understand, the church will consider such marriages as true and real, and may not grant an annulment.
I think my crazy point of the crocodiles, was that both would be equally sinners, if they did not turn from their way of life that was not bringing peaceful waters. But if the heterosexual one did not honor God's laws it would be in less trouble.
As far as baptizing a crocodile, you would have to be very careful, because by the time you Wade out into the river and wake it up, and dunk it under, it might not quite agree with your false doctrine.
I think the moral of the story is not to judge each other, and don't act like Crocodiles.
