A German Catholic cardinal who was ousted from a high doctrinal position by Pope Francis said in a “manifesto of faith” that the church has become too focused on mercy instead of traditional doctrine.

Gerhard Cardinal Mueller didn’t refer to Francis by name, but took jabs at his willingness to allow remarried Catholics to receive Communion, and asserted women cannot be ordained priests. The pope commissioned a study on female deacons. Francis sacked Mueller as prefect of the Congregation for the Doctrine of the Faith in 2017.

Mueller’s manifesto was released late Friday, but carries the date of Feb. 10 — the eve of the sixth anniversary of Francis’ predecessor, Pope Benedict XVI’s historic announcement that he would resign. Many conservative Catholics are nostalgic for the doctrinal clarity Benedict’s reign.
