Mark Shea and Dwight Longenecker are pretty much cut from the same Novus Ordo cloth.
Yes, varying only in degrees. Sadly, I would have to agree with you. It's like an Our Sunday Visitor Catholic and a Wanderer Catholic, if that makes sense. I met Mark Shea early on in my conversion out in Seattle area. His books on the Senses of Scripture and Mary actually helped me a lot. But he has moved to the left so much in such a short period of time, and I left the N.O. after my religious order was disbanded (a good thing, but for corrupt reasons). Reaching out on CathInfo actually put me in touch with good Traditional Catholics in my area who had already arrived at the conclusions about the Crisis that I was just discovering.
