What are the sources for the life of Jesus of Nazareth?
seems to depend on traditions (and perhaps already shaped sources) received in Greek – in other words not first hand accounts from any of the apostles. Parallels have been detected between Mark and Paul’s Epistle to the Romans.and 1 Corinthians. Some have suggested that Mark’s Gospel is an elaboration of material he found in Paul’s epistles, and that he created the person of Jesus of Nazareth.
