I've read a few of Frank Shaeffer's Regina Orthodox Press publications, "The Truth" and "The Faith," by Clark Carlton, and "The Complete Book of Orthodoxy," by George W. Grube, and find them most enlightening and informative.
During the Primacy of Archbishop Spyridon of America, of the Greek Orthodox Archdiocese of America, ('96-'99), His Eminence, who was rather traditional, had endorsed Mr. Shaeffer's works. Shaeffer was a Parish Council member of a GOAA parish at the time, on the East Coast (Massachusetts?), if I recall correctly. Ron Dreher, an Orthodox Christian, claims in a year or so old "The American Conservative" article that Shaeffer doesn't believe in God, but maintains membership in the Greek Orthodox Church and receives Holy Communion therein. That's awfully strange.
I'm a Conservative Republican and have seen Shaeffer on MSNBC. I don't agree with his political opinions, though I see merit to statements he's made about the Religious Right and their involvement in church activities. Never-the-less, Regina Orthodox Press is an asset to Orthodox Christians who read about and study their faith in the English language.
