The Society of St Pius X (SSPX) has accused Pope Francis of spreading confusion and errors about the faith. A statement from the traditionalist group suggested that a new attempt at reconciliation with Rome had stalled, and that the society was divided over next steps. The statement indicates that the SSPX believe that “painful confusion” currently exists within the Church and considers “a large number of pastors, including the Pope himself” responsible for what the group regard as doctrinal errors in teaching. The SSPX believe that the “cult of man” has replaced the worship of God. The statement added that the SSPX conduct “penance” for the actions of the Pope in the hope that he one day may “have the strength to proclaim Catholic faith and morals in their entirety.”

The statement, in full:

The purpose of the Society of Saint Pius X is chiefly the formation of priests, the essential condition for the renewal of the Church and for the restoration of society.
In the great and painful confusion that currently reigns in the Church, the proclamation of Catholic doctrine requires the denunciation of errors that have made their way into it and are unfortunately encouraged by a large number of pastors, including the Pope himself.
The Society of Saint Pius X, in the present state of grave necessity which gives it the right and duty to administer spiritual aid to the souls that turn to it, does not seek primarily a canonical recognition, to which it has a right as a Catholic work. It has only one desire: faithfully to bring the light of the bi-millennial Tradition which shows the only route to follow in this age of darkness in which the cult of man replaces the worship of God, in society as in the Church.
The “restoration of all things in Christ” intended by Saint Pius X, following Saint Paul (cf. Ep.h 1:10), cannot happen without the support of a Pope who concretely favors the return to Sacred Tradition. While waiting for that blessed day, the Society of Saint Pius X intends to redouble its efforts to establish and to spread, with the means that Divine Providence gives to it, the social reign of Our Lord Jesus Christ.
The Society of Saint Pius X prays and does penance for the Pope, that he might have the strength to proclaim Catholic faith and morals in their entirety. In this way he will hasten the triumph of the Immaculate Heart of Mary that we earnestly desire as we approach the centennial of the apparitions in Fatima.
