I am a practicing Catholic and have been for most of my almost eighty years on this planet.
One thing that I find abhorrent is to hear and read a fellow Catholic say that he is proud to be Catholic.
But for the grace of God, we could all be atheists. It was pride that drove man out of paradise and we are still paying the price for it in our daily sufferings in spite of Christ’s supreme sacrifice in order to open the door to heaven.
I never hear anyone say that he is humbly grateful to be Catholic.
I've seen it said a few times over the years, and it be acceptable at face value due to that person's overall demeanor, which itself carried testimony towards the affirmative.
At risk of getting personal, you do come across as being genuinely one of those.
