What does the following sentence mean?
"Like all good unorthodoxies, pantheism drew a sound papal spanking, this one from Pius IX’s 1864 Syllabus of Errors."
This reminds me of a definition that has now been removed from SOED.
Abbreviator: papal official who draws up the Pope's briefs.
But as MikeNY said, the 'papal spanking' here is a tongue-lashing given by the Pope.
