I have been there and thought it was nice,and had many problems with it also, but you know what? It doesn’t (shouldn’t) really matter to us. There are good messages that come from there, but since it is not approved, why bother with it?
St. John of the Cross when speaking on discerning these sort of things (private revalation) states to not even to bother discerning them at all, because if they are from God and God wants you to know, they will not go away etc. etc…the important thing is to bring them to your confessor and do what your confessor and follow him.
Also, I have noticed that a lot of people following the appartions seem more excited about the miracles than our faith itself…I have been in this situation…anyway, we need to stick by our Church especially in these trying times, and always…Our Blesses Mother will not shun us for that at all…You could even tell her “Mother, I don’t care if you are appearing or not in Medjugorje, it does not concern me, but I do know that I want to be you servant, so that you may keep me always close to the Heart of Jesus”…that is probably what she wants to hear…
