Peter Julian Eymard, French priest and founder of the Congregation of the Blessed Sacrament (born 1811)

Peter Julian Eymard was a French Catholic priest and the founder of two religious institutes: the Congregation of the Blessed Sacrament for men and the Servants of the Blessed Sacrament for women.

The Congregation of the Blessed Sacrament, commonly known as the Sacramentinos, is a Catholic clerical religious congregation of pontifical right for men, founded by Peter Julian Eymard. Its members use the postnominal letters S.S.S. They assist the Church in her efforts to form Christian communities whose center of life is the Eucharist. They commit themselves to the implementation of this ideal in collaboration with lay men and women engaged in various ministries.
