I am a sinner, we have that in common, the difference is I believe what the Bible teaches regarding homosexuality. My concern is that if I apologize for my belief that homosexuality is a sin, (in other words I am judging them based on the Bible’s teachings), that I would be saying the Bible is wrong.
Well that’s easy for you isn’t it, since you aren’t homosexual. Moreover you would not apologizing for your belief that homosexuality is a sin. That’s not what the Holy Father is saying. He is saying we should apologize for
discrimination against gays, which the CCC also admonishes us to avoid but often fail to in either overt or subtle ways.
I am not gay but I’ve had enough experience of my personal sins to say “there but for the grace of God go I”, and work on my own sin while leaving gays to find their own path to God, and leaving the teaching, absolving, chastising, prodding along, etc. to their pastors, spiritual directors and confessors.
What I can do as an individual Christian Catholic however, is to contribute to making the Church a warm and welcoming place for them so that they can find at least the starting point of that path towards God, and the people qualified to lead them along it.
That means being kind, welcoming, listening, and charitable, and avoiding pounding my finger on the Bible or Catechism to “prove” that they’re headed to damnation. If I do something to turn them away from the Church, then I have as much to answer for on judgement day, and perhaps even more, than they do.
I’ll let them work out their sins, while I work on mine, but I will welcome them into the Church with open arms even if they are nowhere near where the Bible and Catechism says they should be striving towards. None of us are, actually.
So if you see a new person you suspect is gay in your parish, chat with him/her at coffee hour or after Mass, be welcoming, and don’t talk about their issue. Just chat about the weather, or life in general. If a gay person shows up at Church it is because they are seeking God, even if they are currently in a state of rebellion against Him. I too was in that state when I returned to the Church 19 years ago after a 22-year absence.
