I came across this snippet in a commentary by John Walvoord, I do not know enough to validate its accuracy, but thought it was intriguing enough to look into. Here is his quote:
Crowns in the shape of a fish head were worn by the chief priests of the Babylonian cult to honor the fish god. The crowns bore the words ‘keeper of the bridge,’ symbolic of the ‘bridge’ between man and Satan.
This handle was adopted by the Roman emperors who used the Latin title Pontifex Maximus, which means ‘major keeper of the bridge.’ And the same title was later used by the Bishop of Rome. The pope today is often called the pontiff, which comes from pontifex.
I have come across one Catholic source that says pontifex means “bridge builder,” but they include nothing about fish gods.
The Latin Vulgate translates “high priests” of the Jewish religion as pontifices (plural) or pontifex (singular). This is more likely due to the already accepted notion of pontifex referring to a church leader when the Vulgate was being translated.
I have verified that early Roman Emperors after Christianity became the official religion, used the title.
I also came across an article talking about the pope’s hat that looks like a fish’s head, which is traced back to the Babylonian fish god, Dagon. It goes something like this:
A lot of Evangelical commentators during the 1950’s had a field day with Catholicism, including My Boy, Harry Ironside, who said the pope is “the direct successor of the high priest of the Babylonian mysteries and the servant of the fish god Dagon, for whom he wears, like his idolatrous predecessors, the fisherman’s ring.”
Certainly there are threads of continuity with pagan religion, I find that to be undeniable. To say this is “direct succession” might be a stretch. However, it has more to do with Dagon than direct succession with the Apostle Peter.
In the end, there are many reasons I am not Catholic. This is one more.
