Dogmatic sedes would have you believe that you are required to make up your mind about whether the Pope is a heretic or not, in order to be truly Catholic.
Why would our Lord Jesus Christ expect such a complicated decision to be made by faithful when theologians have struggled with it right up until the 20th century.
Common sense prudence tells us we stay away from things that don't look Catholic. So that means the novus ordo, liberal clergy etc. etc.
We should not have to be able to quote various quotations from theologians on the vacancy of the Papacy, like some pompous fool outside Church, in order to be a good Catholic.
It is absurd on it's face, and shame on dogmatic sedes for even implying it.
