If I as a protestant decided to attend a catholic church (I was raised catholic) and take communion...that’s between me and the Lord. The people there don’t know anything about me one way or the other, it has nothing to do with them.
if you were raised catholic, then you know why you shouldn’t. If you choose to anyway, no one is going to know unless you announce it first. Why bother on here if you already know the answer. You will face your maker one day and if you decide to remain outside the church or take communion in it while not a member, its your problem, not anyone elses. Sin is sin, and if you know from being raised catholic its a mortal sin whether you like it or not.
I may add you were not raised an informed catholic or you would still be one. I am not going to answer any further posts, as you are here to disrupt and either you know better and just don’t care, or you want to incite. Either way, Pax Christi to you. Good day.
