All of this “Satan” talk is completely out of context. There is absolutely nothing wrong with somebody in a religious context talking about Satan being loose in the world. There is almost nothing that Rick Santorum said that wasn’t in line with the fictional but theologically sound take on the forces of eveil that C.S. Lewis described in The Screwtape Letters. And there is absolutely nothing that isn’t standard Catholic doctrine. Consider that for years every Catholic Church recited, ever week, the prayer to St. Michael the Archangel, pasted below, and that many Catholic churches still do. This includes the Catholic Church in Alexandria, VA that is the home parish for a host of leading conservative Catholics in the DC area. Here is the prayer as regularly recited (the link above is to the long version and the history thereof):
Saint Michael the Archangel, defend us in battle, be our protection against the malice and snares of the devil. May God rebuke him we humbly pray; and do thou, O Prince of the Heavenly host, by the power of God, thrust into hell Satan and all evil spirits who wander through the world for the ruin of souls. Amen.
To complain about what Santorum said is to show an appalling lack of perspective and understanding of Catholicism, of Christianity, and of religious faith in general. Those complaining should be ashamed of themselves — it, that is, they had any shame.
