Bread Of Life

The Society of St. Pius X is an international priestly society of common life without vows, whose purpose is the priesthood and that which pertains to it.
 
The main goal of the Priestly Society of Saint Pius X is to preserve the Catholic faith in its fullness and purity, to teach its truths, and to diffuse its virtues. Authentic spiritual life, the sacraments, and the traditional liturgy are its primary means of bringing this life of grace to souls.
