The former prefect for the Congregation of the Doctrine of the Faith has called the working document on the Amazon Synod “false teaching.”
False teaching comes from (2 Peter 2:1-3) which speaks of “false prophets” and people bringing “swift destruction on themselves” . It even speaks of Apostasy “Denying the Master who brought them” (vis-a-vis 2 Peter 2:1).
There are parallels with AntiChrist passages. This chapter also speaks of the destruction of Sodom and Gomorrah (2 Peter 2:6) and condemnation to Hell through a grave moral fault: adultery to the Gospel (2 Peter 2:14).
Mueller (Muller) has condemned many acts and teachings of Francis, including his reorganization of the hierarchy which many prelates have condemned. Although, Mueller has been ambiguous in some respects regarding Francis. His positions have strengthened against Francis and currents of false teaching in the Church in the past few months.
Prophetic: Mueller is growing in holiness. He has been showing his increasing resolve. In time to come, he will be a strong force in the Church (prophesied 5+ times in the prior 2 years).
