These three pastoral epistles were accepted as genuine by most of the ante-Nicene Church Fathers. Some scholars have argued that the letters were certainly accepted as Pauline by the time of Irenaeus (130-202). They were also included in the Muratorian fragment (170). Marcion (85-165)’s theology would have been the cause of why he rejected these letters since it was incompatible with certain passages. Certainly, these letters would be considered anti-Gnostic. In the mid-second century there was a common belief that these letters were written by Paul. Does it matter to you when these pastoral letters were written?
