Q. 1. I recently heard someone make reference to "swum the Tiber" when sharing his conversion. What does that expression mean?

A. 1. "Swum the Tiber" is an expression that means to "cross over to the Catholic faith." You see, the Tiber river runs through the city of Rome. On one side is located St. Peter’s which is one of the largest Church in the world that is regarded as one of the holiest Catholic sites. In this expression, non-Catholics are considered to be on the opposite side of the Tiber river. To join the Catholic faith, they have to symbolically swim across the Tiber river in order to enter St. Peter's Cathedral.
