Sometimes it can hard to tell where the line is on certain topics because you would think that everyone would agree that X is bad (or whatever your point in posting over there was; I didn't see the post/s in question, since I don't go to OBOB very often), but then there's also the question of why exactly it needs to be said if you are indeed correct about that. For instance, I don't spend any time defending Trinitarianism here on TAW (or anywhere outside of the "Debate Other Religions" section, because that's where the the non-Trinitarians are), because it would be kind of pointless. It's not needed, and if it is needed then the people here can best defend their own Church. At best if I have any role as a guest anywhere it is to agree with what is agreeable and defend in the sense of not providing succor to the enemy who may come (t)here to preach something else using examples that would include me and my Church (because a lot of people tend to invoke the Chalcedonian schism in weird ways, e.g., to make a case of Roman Catholicism in particular -- as I have seen here on TAW -- without realizing that this is inappropriate and will not work, because the OO share many of the same objections to RC doctrine for mostly the same reasons as stated by EO).
Otherwise, what is the point of involving oneself in a situation that has no possible connection to you or your Church? Isn't it best to pray for those suffering in the RCC as a result of things like the pedophile situation and the protection of pedophiles, both of which are abhorrent to the faithful of every communion? I do not see the point of doing otherwise. Is it to treat the RCC as though it is a puppy, and rubbing its nose in its own mess will teach it something it can't learn better by loving but firm correction when appropriate (say, if one of them were to come here, where the congregational forum rule is in your favor)? Its change as an institution and a collection of people seeking to worship God, its metanoia if you will, must come from inside, just as we all must demonstrate our own metanoia before the Lord, right?
And that is far harder than posting whatever everyone will already agree with on a message board, I would think. It is the hardest saying of the Desert Fathers, for me personally, that true humility is to admit that you have done nothing good before God (since we all want to say we have done good in standing up to evil, wherever it comes from and however it manifests itself). And further another of these holy men (forgive me for not having citations on hand; I am away from my copy of the collection of their sayings, but it is in Benedicta Ward's translation, I believe) is recorded as having said that if he could ever truly see the full enormity of his own sins, there would not be enough monks in all the monasteries in all of Egypt to weep over them. And of course there were many more monks and many more monasteries at that time then there are now. Lord have mercy.
