The Congregation of the Companions of the Holy Saviour (CSSS for Congregatio Sociorum Sancti Salvatoris) is an Anglo-Catholic dispersed religious order founded in 1891 at the former Church of the Evangelists in Philadelphia (now the Samuel S. Fleisher Art Memorial).
It was subsequently affiliated with the former S. Elisabeth's Church in Philadelphia.
CSSS founder William McGarvey became a Catholic in 1908 due to the allowance of non-Episcopal Protestant clergy to preach in Episcopal churches.
During the second half of the twentieth century, several members were connected with the Church of the Annunciation, Philadelphia.
In 2022, the Master of the CSSS is Bishop Barry E. Yingling of the United Anglican Church.
