Adjective
Matthean (not comparable)
Of or relating to Matthew the Apostle.
The Matthean text seems to be dealing with what to do when someone sins against us while the Galatians text is dealing with someone who is caught up in a transgression that may or may not be a sin against us (I think). Source: Internet
That Justin did not entirely formulate it ad hoc is demonstrated by the close parallel in the Proteuangelium Iakobi (PJ 11:3), where much of the same combination of Matthean and Lukan elements occurs. Source: Internet
For Matthean and Lukan chronologies replicate Mark’s, their primary source; whereas John and, before him, Paul take other directions. Source: Internet
