Factual error: When Brad and Kate are in the taxi on the way to the airport, they are shown crossing the Golden Gate Bridge. They supposedly live in the city of San Francisco itself, and therefore should be heading south to the airport. The Golden Gate Bridge is to the north, and is completely in the opposite direction, by about 18 miles.
Factual error: During the Nativity play, Pastor Phil says, "Are we ready to see the result of the Immaculate Conception?" The term 'Immaculate Conception' refers to the conception of the Virgin Mary (conceived without Original Sin), not to the conception of Jesus. Furthermore, the Immaculate Conception is a dogma of the Catholic Church, and not something which a Protestant pastor like Phil would believe in.
