I would do the same for anyone, not just homosexuals, who find themselves at odds with the Church, be it the divorced & remarried, those in irregular marriages/common law unions, gays whether in a so-called “marriage” or not, transgendered, pro-choice Catholics, and the list goes on. Catholics have no shortage of means to separate themselves from God. However this thread is about the LBGQT community.
Gays are perhaps different in that they have a large, loud and active lobby promoting their “cause”, whereas I see no such movements for the D&R or irregular (heterosexual) unions.
I was one of these once, in an irregular (civil) marriage that I entered when I was a lapsed Catholic. Fortunately the local Church was welcoming to me when I came home, and didn’t put pressure on me to regularize my situation; the priest knew that I knew what I had to do. It took a while to get my wife on board (an evangelical Anglican). I won’t go into the gory details here, as it is part of my private life, but suffices to say that I think the same extended welcoming hand should be available to all who are on the outside, and want to come back home but in the meantime made a mess of their lives and need help and a strong dose of grace to get it back on the rails. My wife and I did eventually have our marriage convalidated perhaps too many years later than we should have, but better late than never. That would not have likely happened if I was turned away for being at less than the ideal stage in my Christian walk.
