There is in essence but one gospel, differently presented by Jesus and Paul, whose focal point in the teaching of both is Christ and Him crucified. The differences, as shown by von Dobschütz in a notable essay, explain themselves naturally from the situation. In John and Paul there is only expansion and repetition of what was contained implicitly in the words of Jesus in the Synoptists. The later time was not creative, but only selected and developed; its message was an echo, not a new utterance. In the teaching of Paul as compared with that of Jesus there are three points of difference: (1) the person of Jesus is much more strongly emphasized; (2) His death and resurrection appear as basal redemptive acts; and (3) everything is brought into connection with redemption from sin. All three of these differences are explained by the historical situation. Jesus Himself had brought them to God, and His resurrection had brought them out of their despair and strengthened their faith and given them courage for preaching. As to the differences, two considerations should be borne in mind: "That the gospel should be differently set forth before the death of Jesus than it was after that event is not to be wondered at; and, secondly, it is also natural that the standpoint and exposition of the recipients of grace should be different from the attitude of One who was free from sin, and knew that He was sent to bring man to God."[50] 50: "Gibt es ein doppeltes Evangelium in N. T.?" _Theol. Studien u. Kritiken_, 85 (1912), pp. 362, 363. In the future as in the past, we may believe, doctrinal Christianity, that is a Christianity broad enough to include the teaching and example, and the person and passion and resurrection of Christ, will be for men and nations the power of God unto salvation. If the essence of a thing is shown in its activity, the essence of Christianity cannot be separated from its doctrinal content. Certainly it was Christianity in a doctrinal form that inspired the greatest achievements of the Christian Church in the course of her history. It was doctrinal Christianity that loosed the bonds of Jewish legalism, inspired the missionary enterprise of the primitive and the modern church, raised the standard of the Reformation, laid the foundations of modern democracy, and guided the sanest and bravest attempts at social reform. Our argument has been that the primitive gospel which began to be preached by the Lord was a doctrinal gospel, a gospel of the Kingdom, the Cross and the Son of God, that no other message can be found with any distinctness within or beneath the Gospel records, and that this has been at the basis of Christian experience and of the life of the Christian Church. The gospel of the grace of God is the gospel of the glory of Christ. II The Christian Faith and Modern Science
