If you listen to Fr. Trenham's lectures like I do, you'll see that he recommends a lot of secular figures, quoting them often. He does read secular books to keep his pulse on the cultural winds. It's unfortunate that detractors are using one of his recommendations in an attempt to wipe out his whole ministry. I see this as a demonic attack against him.
Respectfully, I disagree.
Jordan Peterson is not just another secular figure; he's a cultural phenomenon. How we as Christians react to such trends tests our faith.
In the case of Peterson, are we Christians willing to ally with a heretic (Peterson), who appears to be a demoniac, just to win a temporal Culture War?
Fr. Trenham's ministry is great, but everyone has his stumbling blocks. I don't think this speaks to Fr. Trenham's ministry, but rather his particular failings in individual discernment. I am of course glad that the father has gained many souls for Christ.
