I. To the Question

50. I reply: it is not simply necessary, according to that verse at the end of Mark 16.16, “Who will have believed and been baptized will be saved;” and Gratian, Decretum p.3 d.5 ch.2, where is contained that someone baptized is saved by baptism alone. However, confirmation is necessary for an adult, in such way, however, that he not contemn it, as said in Decretum ibid., where the gloss says [Gregory IX, Decretals V tit.39 ch.43], “he is not a full Christian who contemns it.”
