"Paul is out earliest literary authority for the historical Jesus. True, he does not tell us much about the historical Jesus, in comparison with what we can learn from the Evangelists, but he does tell us a little more than that Jesus was born and died. Jesus was an Israelite, he says, descended from Abraham (Gal 3:16) and David (Rom. 1:3); who lived under the Jewish law (Gal. 4:4); who was betrayed, and on the night of his betrayal instituted a memorial meal of bread and wine (I Cor. 11:23ff); who endured the Roman penalty of crucifixion (I Cor. 1:23; Gal. 3:1, 13, 6:14, etc.), although Jewish authorities were somehow involved His death (I Thess. 2:15); who was buried, rose the third day and was thereafter seen alive by many eyewitnesses on various occasions, including one occasion on which He was so seen by over five hundred at once, of whom the majority were alive twenty-five years later (I Cor. 15:4ff). In this summary of the evidence for the reality of Christ’s resurrection, Paul shows a sound instinct for the necessity of marshalling personal testimony in support of what might well appear an incredible assertion..
Paul knows of the Lord’s apostles, of whom Peter and John are mentioned by name as “pillars” of the
community (Gal. 2:9), and of His brothers, of whom James is similarly mentioned (Gal. 1:19; 2:9). He knows that the Lord’s brothers and apostles, including Peter, were married (I Cor. 9:5), and incidental agreement with the Gospel story of the healing of Peter’s mother-in-law (Mark 1:30). He quotes sayings of Jesus on occasion, e.g., His teaching on marriage and divorce (I Cor. 7:10f) and on the right of gospel preachers to have their material needs supplied (I Cor. 9:14); and the words He used at the institution of the Lord’s Supper (I Cor. 11:24ff).

Even when he does not quote the actual sayings of Jesus, he shows throughout his works how well acquainted he was with them. In particular, we ought to compare the ethical section of the Epistle to the Romans (12:1-15:7), where Paul summarizes the practical implications of the gospel for the lives of believers, with the Sermon on the Mount, to see how thoroughly imbued the apostle was with the teaching of his Master. Besides, there and elsewhere Paul’s chief argument in his ethical instruction is t example of Christ Himself. And the character of Christ as portrayed in the Gospels. When Paul speaks of “the meekness and gentleness of Christ” (II Cor. 10:1), we remember our Lord’s own words, “I am meek and lowly in heart” (Matt. 11:29). The self-denying Christ of the Gospels is the one of whom Paul says, “Christ did not please himself” (Rom. 15:3); and just as the Christ of the Gospels called on His followers to deny themselves (Mark 8:34), so the apostle insists that, after the example ofo Christ, it is our Christian duty “to bear the infirmities of the weak, and not to please ourselves” (Rom. 15:1)….”
