where was the baptismal font? the holy water fonts were actually a way to make the baptismal font more accessible to those entering the church, since in larger churches it is not always possible for everyone to use the water from the font, which is what the holy water actually is, and why we use it, as a reminder of our baptism. Most newer churches have a much larger baptismal font at the main entrance, ideally with a pool for immersion baptism. it actually should be the only source, since multiple symbols are discouraged, although smaller holy water fonts may be placed at other frequently used doors.
