Are you toying with me and turning me around in an impossible maze of logic? For now you enter by the way you left, and then you leave by the way you entered. Or are you weaving some wonderful web of divine simplicity?
— Boethius
The doctrine of divine simplicity (DDS) holds that God is absolutely metaphysically simple. In Catholic theology, this doctrine has the status of a formal dogma as defined by Lateran IV and reaffirmed by Vatican I. The DDS is commonly understood to entail that everything in God (i.e., everything intrinsic to God) is identical to God (cf. St. Thomas Aquinas, ST I.28.2 ad 1).
