Tornielli: “Peace” agreement reached between Vatican and Lefebvrians

[archdiocesan]

A lot of people will get hung up on this:

a Catholic is required to comply “with religious submission of will and intellect” to the teachings that the Pope and College of Bishops “set when they exercise their authentic Magisterium”, even when they are not stated in a dogmatic fashion

but this is simply the traditional teaching of the Church, and is what you can find in any manual from before Vatican II. The important thing to remember is that it refers to when the Pope and College of Bishops

exercise their authentic Magisterium

and not, say, when they give an interview, or give a speech at a summit, or whatever.
