(46)Jesus’ major teaching was the gospel (creed: 1 Cor. 15:1–4), (47)which he received from God and later imparted to his apostles (Clement; Barnabas). (48)The apostles were fully convinced of the truthfulness of the gospel and they, in turn, preached the Kingdom of God everywhere (Clement).

The tendency among some of the secular sources was (49)to view Jesus as a philosopher with some distinct teachings (Lucian; Mara Bar Serapion; cf. Gospel of Thomas). For instance, Lucian refers to Jesus as a “sage.” Lucian and Pliny, in particular, corroborate some of the major teachings of Jesus as mentioned earlier in the Christian sources.
