Faith
Gibson was raised a sedevacantist traditionalist Catholic (who reject the validity of all Popes since the Second Vatican Council and hold that the Holy See is currently vacant). His father Hutton Gibson was an ardent sedevacantist and a Holocaust denier who held strong antisemitic views and supported various conspiracy theories.
