From a sedevacantist assumption that the 1968 episcopal consecrations are invalid, is Mons. Rifan a validly consecrated bishop? Dario Card. Castrillon Hoyos, consecrated in the 1968, was principal consecrator, but Mons. Licinio Rangel, consecrated in the traditional rite, was a co-consecrator.

At the 06:27 mark, Dom Licinio Rangel, I think, if not he is the first one, lays his hand and recites something, maybe the rore santifica.
