It doesn't really contradict the others. With every passing study, with every passing year, with every passing Vatican debacle, with every passing collapse of Novus Ordo fantasies, it has become clearer and clearer we are indeed in the state of necessity Archbishop Lefebvre warned about and resisted. Truth has a way of rising to the surface. So do the errors perpetrated by this Pontiff in the name of novel doctrines.
Since Cardinal Cassidy would have been one of those creating the "state of necessity" by his ecumenical actions, it would seem rather unlikely that he would support the consecrations of Msgr. Lefebvre based on such a state.
