  Godfrey defends the matter-form composition of corporeal beings but rejects any kind of spiritual matter and therefore any matter-form composition of spiritual entities (Wippel, 2012). He also opposes the strong tendency within the Franciscan tradition, also promoted by Henry of Ghent, that would assign some minimum degree of actuality to prime matter. According to Godfrey prime matter is pure potentiality and can never be kept in existence without some substantial form, not even by God. Prime matter and substantial form are directly related to one another as potency principle and act principle. Neither is a being in its own right, but both are principles of one and the same composite entity (Quodlibet XIV, q. 5, PB 5.404–05).
