OK, I know that Wikipedia is not the most reliable source of information but I was able to learn the names of Abp. Lefebvre's two co-consecrators: Alfred-Jean-Félix Ancel, Jean-Baptiste Victor Fauret. So, even if Card. Liénart withed his intention, he still performed the correct form and matter and most likely one of the two co-consecrators had the right intention. In my opinion, Apb. Lefebvre always was a true Catholic priest and a true Catholic Bishop. May his soul rest in peace.
