And yet he still hasn’t declared Francis a heretic and false pope.
Not in the same words "heretic and false pope" that you mention. But this from October 25, 2020 Archbishop Vigano's open letter to the President of the United States of America.
In Sacred Scripture, Saint Paul speaks to us of "the one who opposes" the manifestation of the mystery of iniquity, the kathA"kon (2 Thess 2:6-7). In the religious sphere, this obstacle to evil is the Church, and in particular the papacy; in the political sphere, it is those who impede the establishment of the New World Order.As is now clear, the one who occupies the Chair of Peter has betrayed his role from the very beginning in order to defend and promote the globalist ideology, supporting the agenda of the deep church, who chose him from its ranks.
