Saint Cuthbert
God of common sense, wisdom, zeal, honesty, truth, and discipline.
He is a Lawful neutral intermediate Deity from Greyhawk who is thought to have been human once. His favored weapon is the mace both heavy and light.
His first published appearance is in the module "The Village of Hommlet", which is the prologue to the famous Temple of Elemental Evil adventure. He was depicted as an older, stocky man, whose idea of doing good was to beat the evil out of people with a big stick -- a lot more tough-love than your typical paragon of lawful-good.
