John MacArthur's anti-Catholicism

What's the current flap about John MacArthur, an evangelical pastor, I wondered? So I googled what he said about Catholics and the Pope. Actually, there were so many entries going back 7 or 8 years, I couldn't even find the reference I was looking for and had to go to his website and click on his blog. If Christians wonder why youth, gays, non-Christians and young families are leaving the sanctuary and Sunday classroom for feel-goodism, Eastern meditation routines and la-la spirituality, they only need to look at their own nasty in-fighting and name calling. And he calls his web site, "Grace to you?" I wonder if this Bible believing teacher/preacher has heard of St. Jerome? Does he know that before the canon, there was tradition, liturgy, priests, bishops? His rants are like people libeling their great grandparents whom they never met. Evangelicals believe in the pope--the one they see in the mirror every morning.
