In Issue 24, Fr. Chazal states the following:
"Yet again, allow me to repeat that the jurisdiction of a public heretic is illicit ipso facto....."
The jurisdiction of a public heretic is not only illicit ipso facto, but it is also invalid ipso facto. A public heretic is not a member of the Church. Heresy per se separates the public heretic from the Church.
Actually, they're both wrong:
Juridical acts remain valid and licit unless a declaratory or condemnatory sentence is declared.
1917 Code of Canon Law, Canon 2264:
"Acts of jurisdiction, whether for the external forum or the internal forum, placed by one excommunicated are illicit; and if a condemnatory or declaratory sentence has been laid down, they are also invalid with due regard to prescription of Canon 2261, S. 3 [i.e. the validity and licitness of obtaining acts of sacramental ministry from an excommunicated cleric when one is in danger of death]; otherwise, they are valid and, indeed, are even licit if they are sought by a member of the faithful in accordance with the norm of the mentioned Canon 2261, S. 2 [i.e. seeking sacramental ministry from an excommunicated cleric for any just cause, expecially if other ministers are lacking; no explanation of one's reasons is required]."
In other words, even if Francis is a raging heretic, his acts of jurisdiction would be VALID and LICIT, because he was never subject to condemnatory or declaratory sentence.
