In Italian, the word pope is an endearment meaning “father” or “papa.”
The responsibility of the leader of the Roman Catholic Church is to build bridges between God and mankind.
And the title Pontiff comes from the original Roman reference pontifex, meaning “bridge builder.”
The Holy See is a corruption of the phrase “Holy seat,” or throne, and refers to the place where this throne is housed.
That’s why the Pontiff of the Roman Catholic Church is called the Pope.
