Another argument goes down in flames…
The Case of Pope Celestine III:
A Refutation of Robert J. Siscoe
The Pope is the one on the left
The master theologians of the recognize-and-resist camp are just too smart for their own good. On Feb. 21, 2017, Remnant contributor and True or False Pope? co-author Robert J. Siscoe published what he thought was a slam dunk against Sedevacantism. In an essay entitled “Pope Celestine III’s Error on the Indissolubility of Marriage”, published in the online edition of The Remnant, Siscoe argued that Pope Celestine III (1191-1198) had committed a serious doctrinal error which was later incorporated into universal Church law by Pope Gregory IX.
