Those, then, are to be believed, who hold firmly to the truth. And we may broadly make use of this reply, and say to them, that physicians holding opposite opinions according to their own schools, yet equally in point of fact treat patients. Does one, then, who is ill in body and needing treatment, not have recourse to a physician, on account of the different schools in medicine? No more, then, may he who in soul is sick and full of idols, make a pretext of the heresies, in reference to the recovery of health and conversion to God.
