John Geddes MacGregor (13 Nov. 1909–9 Oct. 1998)[1] was an author, scholar of philosophy, educator, and an ordained Episcopal priest.
MacGregor was born in Glasgow, Scotland in 1909, and his early life was spent in Edinburgh, Dundee, and in continental Europe.
[2] MacGregor was raised Presbyterian, but as a young man in Edinburgh he converted to Roman Catholicism under the influence of Canon John Gray of Saint Peter's, Morningside.
[3] A few days after his Episcopal ordainment, he was named canon of Saint Paul's Cathedral in Los Angeles.
"[7] In 1967, the Commonwealth Club of San Francisco honored MacGregor's book, The Hemlock and the Cross: Humanism, Socrates and Christ, as the year's best nonfiction work by a California author.
