Despite his lack of recognition in this field in his own time, Anselm is now famed as the originator of the ontological argument for the existence of God and of the satisfaction theory of atonement.

And there went forth a wind from the LORD, and brought quails from the sea, and let them fall by the camp, as it were a day’s journey on this side, and as it were a day’s journey on the other side, round about the camp, and as it were two cubits high upon the face of the earth. Numbers 11:31 KJV

Ontological argument (Wikipedia) An ontological argument is a philosophical argument, made from an ontological basis, that is advanced in support of the existence of God. Such arguments tend to refer to the state of being or existing. More specifically, ontological arguments are commonly conceived a priori in regard to the organization of the universe, whereby, if such organizational structure is true, God must exist.
