Anselm and Thomas Aquinas' arguments for God

1. Apologies for the robotic voice in a couple of these; I did not make them.
2. I do feel that Anselm's argument is easily made fun of as a statement of blind belief. But I think, by looking deeper at it (as those who watch the entire videos will discover), there is more to the argument than meets the immediate eye.
3. More to the point; these arguments and others should push us toward the God that these arguments argue for; general revelation (such as nature, history, and moral concepts) should be backed up by special revelation (the Bible first and foremost for us today).

Regarding why Christianity and not other religions, see here.
