You always need to ascertain whether the priest is faithful to the magisterium. Often you can “know” this based upon his homilies, what he speaks against, what he speaks in favor of, and so on.I agree with what you said here. I think the very sad part is that many Catholics will believe anything a priest tells them just because he is a priest. Often here on the forum people give others the advice " see a priest asap" and I often wonder…if you don’t know the priest, do you just trust him?
In most cases, it would be nice if Catholics would “believe anything a priest tells them just because he is a priest”. Very often people have a “cafeteria” mentality and already have their minds made up that they are going to reject anything they do not want to do or believe.
We are very blessed in the “Internet age” to be able to teach ourselves much, if not most, of what we need to know about the Faith. Time was, people did not really know how to make moral decisions beyond what they had learned (or memorized) from the catechism, and on top of that, they could not defend their faith when attacked for it. Many times they just had to say “I don’t know why I believe X, but it is my faith and that is what I’ve always been taught”. These days, that’s not good enough.
Does anybody ever stop and realize just how blessed we are, to have the sum total of Catholic faith and teaching at our fingertips instantly? We’d better make the best use of it now — “make hay while the sun shines” and educate ourselves. We might not always have this sort of access, and this much information. Not to sound like a conspiracy theorist, but future global dictators and tyrants could “pull the plug”. And there’s always EMP. We may not always have the entire Summa Theologica, Haydock’s Bible, or the writings of the Fathers of the Church available on demand, instantaneously, free of charge, to read at one’s leisure. Think about it.
