III. To the Argument for the Opposite

28. As to the argument for the opposite [n.6], although about some holy fathers it may be assumed that in contracting bigamy they did not sin, because both reasons for contracting bigamy there came together (namely both the necessity because of which contracting matrimony in this way was justly done, and also divine authority giving approval and prescription), yet if some did contract without these reasons or one of them, that they sinned mortally is not unacceptable to me, because I do not reckon that they were confirmed.
