names differ are opposed, then Paul and Peter and all people in general must be different in substance28 from one another. But there is no one so stupid and so inattentive to the common nature that he would be led to say this—after all, the passage: You have been formed from clay, as also have I [Jb 33:6] signals nothing other than that all human beings are of the same substance.29 This being the case, whoever evasively argues that difference in substance follows upon difference in names is a liar.
