I take your ad hominem attacks; very well.
No, we’re responding to what you say you do, not to you directly.
But I don’t think its arrogance. I know when people are confessing. It isn’t a power. I have already explained myself. Deductive logic, observation, some reasoning and knowledge of my community. If I were a stranger in a parish it would be different. I am a regular, active member.
Don’t try tell me in your daily life you sit and think everybody is a saint. Rubbish. That to me is arrogant and also a big fat lie. Hate the sin, love the sinner.
No, but I don’t try to figure out who is fit or unfit for communion.What I DO is to give them the benefit of the doubt if I’m aware of another’s sins, the benefit that says that I don’t presume to know the state of their soul.
How does one tell another they are unfit? Simple. Say, friend/brother/sister/whoever have you been to confession lately? It’s just that, the teachings of the Church dictate that you cannot recieve communion unless you have, and while I am not judging you, it is prudent to not recieve communion lest you disobey the Church and worst of all treat the Eucharist without the respect it deserves.
And do you tell an individual once, or do you keep asking them week after week. This might be a mitigating factor in how arrogant your actions seem to appear. Nothing wrong, in the proper time and proper circumstance in helping to remind or inform someone if you think they are ignorant of the church’s teaching in this area. But that wouldn’t be at mass IMHO.
I would rather be highly arrogant and condescending ten lifetimes over than one more person who hasn’t been to confession in ten years take the body and blood of our Lord.
Well, if the shoe fits…

But seriously, where do you think the line should be drawn as to where we should and can involve ourselves in other’s relationship between themselves and their Lord?
Sure, I am not a priest. But since when were we to sit back and do nothing? Since when were we not allowed to tell people the teaching. Even more, if our priest isn’t mentioning it we should tell our friends and community.
Have you spoken to your priest about this?
The bottom line, for me, is that maybe I don’t know someone’s state of grace - but I’d rather be certain they were in a state of grace than unsure if they are not. And not in an arrogant “Oh, now that I know you are in a state of grace I allow you to receive communion” way which is clearly how you perceive things.
Well…that’s pretty much how you described it.
More so that I am sure that our Lord is being taken with reverence, with knowledge of what it means, with respect, with a pure and contrite heart. That way, everybody wins. Jesus Wins, the person wins, our Church as a whole wins, and thus I win.
