Why are you asking me to do your homework? If you really care about this topic, go to Novus Ordo Watch and read what is there. I do think every now and then they say something that is a little.. I don't want to use the wrong word because I agree with them 99.9%.. just think their wording could be a little more refined. They tend to act like all Christian religions are fake and unhealthy and etc.. (my words).. This is a perception I have of them. I have not, however, found any heresy whatsoever in what they say. The same cannot be said for novus ordo clergy.. OMG.. Both Catholics and Protestants find GREAT error THERE!
Well, I already know about Bugnini, Apostate in Chief of Vatican II. And so far, I have not found ONE thing wrong with what Lefebvre wrote and I have read nearly all that he wrote. I have read the entire Bible AND had it read to me at Mass in both NO Churches and traditional.. read to me over and over and over again throughout the last couple decades. I know heresy when I see it. Also, I have my own personal experiences.. which you could never argue with. Novus O priests are rude and largely uncaring, except that there are notable exceptions.. God bless them.
I speak too dogmatically? Well, someone has to.
