I think he’s talking about me because he only has a handful of FB friends. The only other Catholic “friend” is a cousin, who hadn’t posted for a while.
You cannot know for certain who all of his friends are, nor what he means by saying “very Catholic” as if it were offensive. He may be referring to a Catholic friend that doesn’t post bluntly Catholic things on FB, but has done things to alienate his affections in face-to-face meetings by “acting as if he is more Catholic than the Pope.” (Yes, people on FB do still have private face-to-face meetings from time to time!
)
At any rate, if you were tempted to take offense or assume he meant you, you ought to have asked at the time. The thing to do now is to assume the best–that he did not mean you and that he was talking about someone who is offensive in the sense of acting as if he or she is “more Catholic than the Pope”–and let it go, acting as you feel inclined to act yourself. IOW, you neither need to take offense nor change your own actions when someone seems to be passively dropping unwelcome hints to sway you.
If he never does anything similar, either a) he has repented or thought better of this tactic or b) you mistook his meaning. You let it pass, and all is good. If he does something similar again, then you can ask him about it when that time comes, which is a good time to do so. In that case, you will not have to guess at his meaning. You’ll know, because you’ll ask and he’ll have to be blunt or else drop the ploy. If he refuses to be blunt, then you don’t have to pay any attention to him.
If the day comes when he expresses intolerance of your Catholic faith directly, you can tell him that if you can tolerate him, an apostate from your common childhood faith, then the least he can do is to tolerate you. Whether you decide to engage in apologetics is up to you. It will depend on whether an opportunity to bring him back from his error seems to exist…
Above all, let your love for one another be intense, because love covers a multitude of sins. 1 Pet 4:8
My brothers, if anyone among you should stray from the truth and someone bring him back, he should know that whoever brings back a sinner from the error of his way will save his soul from death and will cover a multitude of sins.
James 5:19-20
Do keep your eye on the ball. Pray intensely that he will turn from his errors and return to the faith. Give thanks that he has not lost his desire to fulfill the duty of religion nor his love of the Lord. Ask for grace and the light of truth for him. You may also express this hope to him when you have the opportunity, but do not beat him over the head with it in a way that is more likely to increase his obstinate stance. (Fasting, almsgiving, or doing other penance on his behalf would also be praiseworthy.)
You do not have to rehearse what to say to him, but you ought to ask the Holy Spirit often to give you the words when the time comes, so you will not find yourself turning to your own wit at the very moment you need true spiritual power and protection on your side.
