July 28, 1881
On July 28, 1881, American Presbyterian theologian John Gresham Machen was born in Baltimore. He led a revolt against modern theology and on June 11, 1936, he and others founded the Presbyterian Church of America in Philadelphia in a split from the Presbyterian Church in the United States of America. A suit by the PC(USA) caused the separated new denomination to rename itself the Orthodox Presbyerian Church in 1939. OPC is a separate denomination from the founding in 1973 of another Presbyterian Church in America. Rev. Machen died on Jan. 1, 1937.
