The pagan priests of the mystery religions were called PATORS or PETERS. They had the power to interpret the heathen mysteries. This is further brought out by Bunson in his Hieroglyph, page 545, where he shows that the Egyptians – as The Bible also indicates – called their "interpreters" or priests: PETR, that is, PETER.
Notice some references to these sacred PETRAS found throughout the pagan world.
At the temple of Delphi in Greece, the chief object in the ritual was the PETRA (Pausanius, Bk. 10). At the Acropolis in Athens, Euripides tells us, the niches which held the idols were called the PETRAE (verse 935). It is well known that even the sacred book which was used in the celebration of the Eleusinian mysteries, was entitled "Book PETROMA," PETER-ROMA – PETER'S BOOK (see Potter's Antiquities, vol. 1, p. 356). Remember that the pagan temples were also called after the PETERS. The temple at Elis in Greece was called PETRON Lycophron, verse 159). Pytho at Delphi was called PETRAessa (Olymp. Ode 6). The oracle temple dedicated to Apollo in Asia Minor was called the PATARA and the oracle there was called PATAReus ("Eus" means "person who, one") – (Lempriere's Classical Dictionary, p. 438). Also PATRAE – an ancient town where DIANA had a temple (p. 438), and the oracle in Achaia was called PATRA (Jones, Proper Names of the Old Testament, p. 296).
Examples are too numerous to mention, but this should be enough to show that the name PETER, or its variants, figured very high in every phase of pagan worship. These PETER stones and temples were found all over the ancient world. "There is in the history of every oracular temple some legend about a stone; some reference to the word PETRA" (Bryant, p. 362). The world and history is littered with many example of the term PETER used as a title for a god.
