Another group calling itself the American Church Union was organized in 1908 in response to the Open Pulpit Controversy of William McGarvey and his followers in the Congregation of the Companions of the Holy Saviour (CSSS).
The current ACU organization had offices in New York City, Pelham Manor, and Berkeley, California.
This American Church Union was incorporated in 1947 in California with EIN 13-1883818 and is currently a publishing imprint of the Anglican Province of Christ the King.
The ACU also sponsored a youth wing known as the Servants of Christ the King, with its own rule of life and annual events.
After the decision of most ACU members to join several bodies that left the Episcopal Church from 1976 onward, the Church Union sold its retreat center and mansion at 60 Rockledge Drive, Pelham, New York in order to settle indebtedness toward contracted employees who remained Episcopalians.
