[ultima ratio]

You think an action to disobey in order to preserve traditional Catholicism was INTRINSICALLY evil? What planet are you living on? Did Lefebvre try to assassinate the Pope--or rape a six-year-old? Those would be INTRINSICALLY evil acts. The act of disobedience in itself is not intrinsically evil. It is certainly permitted under certain circumstances--to resist a command to do what would harm the Church, for instance. You need to read up on moral theology.

It's not about what I think. It's what the Church thinks. "Tends to harms souls" is probably more applicable here if you don't like intrinsically evil, although disobedience certainly qualifies as such in some instances.
