  Heatedly debated in the 1270s and 1280s both at Paris and Oxford was the question concerning whether there is one or more than one substantial form in one substance, and especially in a human being. Godfrey devotes considerable attention to this, especially in Quodlibet II of Easter, 1286 and then again in Quodlibet III of Christmas, 1286. These dates are significant because alleged theological difficulties with the theory of unicity of substantial form as advanced by Aquinas and others had led to prohibitions and condemnations of this by the Archbishop of Canterbury, Robert Kilwardby, O.P. on March 18, 1277, a reissuing of this by his successor in that see, John Pecham, O.F.M. in 1284, and finally a new and resounding condemnation by Pecham on April 30, 1286.
