Comments to the “Novus Ordo” of the “Second Vatican Council” currently is in so-called “traditionalist” circles sometimes a statement by Yves Maury (Pius Brotherhood of Marcel Lefebvre) pointed out, that the so-called new Episcopal ordination is invalid. For orientation: 1 the Episcopal ordination is a sacrament. Even if a not Bishop legally would have been determined for the Bishop, he would be Bishop then really only if he received episcopal consecration in a sacramentally valid Rite even. 2. with his heresies, the so-called “Vatican Council II” (V2, 1962-65) founded a new anti-Christian religion.

As a theological justification see E.g. the very short article by Anthony Cekada, “Why the New Bishops Are Not True bishops” (2006), which is specifically against Lefebvre-position is. 5. of course, everyone from the invalidity of this rite can convince if he refuses to clean.
