He was active in liberal politics until Roe v. Wade was handed down. He is the originator of "Neuhaus' Law", which states that "Where orthodoxy is optional, orthodoxy will sooner or later be proscribed".
He expressed my own grief when Pope John Paul the Great died in 2005 so effectively as a commentator on EWTN that I still remember just sitting there in front of the television and letting his powerful and sorrowful words wash over me: "What HE said..." was what I thought. I sincerely hope that other, younger, orthodox Catholics rise to take his place. Rest in Peace.
