I have absolutely no problem with you believing in a Catholic Magisterium. I don’t personally from my side believe it will do anything to your salvation just like I don’t believe a Baptist or a Anglican is doing something “wrong”. Well wrong is I guess a matter of perspective (Obviously not for those obvious ones). And I really mean this sincere and not sarcastic.
I am currently doing some research into the Orthodox Church and I must say I am more inclined to there belief. I am still a far way so I am not converting pretty soon

. But just something like having no distinction between sins. Although yea, one can argue murder is worse than telling a lie, but that’s not the point. In Catholicism there is a clear cut distinction and even literally a list of mortal sins. Where it seems that with Orthodoxy, they rather leave this question to God and dare not interfere. I have a hard time taking the current Catholic Church as the absolute truth given basically everything. And even if some may be the truth, the claim to infallibility would make even one contradiction the catalyst for denying all the other. That is making me very skeptical.
Being a Protestant makes a lot more sense to me, as we also have many controversies but we don’t claim infallibility.
So asking when it ended is a very valid question and I would love to see a current infallible institution.
During all my comments I hope I didn’t sound like " I am right, come and be Protestant". I was rather just asking “Why be Catholic?”. As to me Catholicism comes forth as infallible as every other Protestant denomination (including my own) and thus I cannot say you are wrong. But I cannot say I feel Catholicism is right either.
