 Marsilius advanced his criticism of the use of logic in theology in his discussion of the position of Robert Holcot. Holcot had argued that logically, God can be called the cause of evil. If God is the cause of every thing (entitas) and moral evil (malum culpae) is a thing, then God is the cause of evil. Marsilius acknowledged that the argument is based on true premises, yet the conclusion should not be defended as true because it contradicts faith and therefore might cause confusion among believers. Theologians should not flaunt their personal skills in logic, but always write out of reverence for the divine. Their writings should not erode the beliefs of ordinary people, who are not skilled in logic, but rather aim to strengthen them  spiritually.[31]
