It is of divine law that notorious heretics cannot be considered members of the Church, nor hold any office in the Church. They cannot even possess a valid election. Unfortunately, it is the "resisters" who follow the heresies and novelites of man (such as Archbishop Lefebvre and Fr. Wathan). You have it backwards as usual.
You still have not looked up
Divine Law yet? What seems to be the problem? Perhaps this will strike a chord with you......
Very simply, Divine = God + Law is a law given to us directly from the mouth of God Himself. The Ten Commandments are Divine Law, the institution of the papacy is Divine Law, that the Church will last to the end of time might be said to be Divine Law, but there is no Divine Law
"that notorious heretics cannot be considered members of the Church, nor hold any office in the Church." That particular law is dogmatic sede law because it only comes directly from the mouths of dogmatic sedes which, contrary to Divine Law, effectively leaves the world with no pope, no hierarchy, no priests, no Church at all. That is the *only* result of your dogmatic sedeism.
I understand this will be entirely lost on you, but for the benefit of others whose heads are spinning after reading your novel and twisted dogmatic sede theology; the Church, through a member or members of Her hierarchy, first accuses then judges the sinner, if this does not prompt the sinner to repent, She then dictates which sins are to receive which censures, and She does so primarily for the purpose of prompting the sinner to repent. The primary purpose is not so the Church can run around with glee while shouting the poor bastard has been kicked out of the Church la la la la!
After the Church pronounces Her judgement, Her censures are *always* primarily medicinal in nature with the intent of inducing the sinner to repent, they are never, nor are they ever intended to be an infallible decree that kicks the poor bastard permanently out of the Church and condemn him to hell with no hope at all, no matter how obstinate he is.
You dogmatic sedes really need to stop [mis]using the teachings of the Catholic Church in your feeble attempts to vindicate sedeism. There are no teachings of the Catholic Church that in any way vindicate sedeism, they all only condemn every variation of it.
