That article is from 2016, did something happen recently to bring attention back to this article
Yes:
Muller is getting lots of media attention from the indult crowd lately (eg., see Michael Matt’s Remnant website, and CIC conference), with his comments on the dead-end dubia, criticism of Francis, being invited to the Synod of Satan as a counterbalancing (but still conciliar) voice.
I pulled this article because it shows what he (like BXVI) really intends for Tradition.
But there won’t be two wild-eyed modernists like Francis elected back to back.
They need Muller/Ratzinger types to sell it to the skeptics.
After Pius XII, you had Roncalli.
After Paul VI, you had JPII the Great
After BXVI, you had Francis.
In other words, two steps forward, one step, eh, well, forward. But alternating between the two, both always heading in the same direction.
Muller is on deck.
