“Primitivism” is rooted in Protestantism (as was the post-VII reductionist assault on the Mass). Theologians who promoted the possibility of universal salvation in contradiction of Scripture (e.g. Rahner and von Balthasar) also got into the act (note the mistranslation of “for many” to “for all” that was only recently corrected). The facts are available for anyone willing to do a bit of research.
I forgive those folks who in trying to promote TLM bash those who attend and love the NO as well. Have a good and blessed Happy/Holy Easter Season!
