(c) The Significance of the Cross.--Nevertheless, the meagerness of the early teaching must not be exaggerated. In the very first missionary speech of Peter, Jesus was represented as "delivered up by the determinate counsel and foreknowledge of God." Acts 2:23. What happened "by the determinate counsel ... of God" was no meaningless chance; the crucifixion was not a victory of evil over God, it must have had some beneficent purpose. Furthermore, Jesus himself had explained what that purpose was. He had spoken of giving his life a ransom for many, Mark 10:45; still more plainly, on the last solemn passover evening, he had represented his death as sacrificial. These words were certainly not forgotten in the Jerusalem church; they were called to mind in the repeated celebration of the Lord's Supper, and must have formed the subject of meditation. The Jerusalem Christians knew that Jesus' death was a death on their behalf.
(d) The Lordship of Jesus.--The lordship of Jesus, moreover, was fully recognized from the very beginning. The risen Christ had ascended into glory, and had poured forth his mighty Spirit. The believer was no mere learner of the words of a dead teacher; he was called into communion with a Lord and Saviour. Such communion meant nothing less than an entirely new life, in which sin could have no rightful place. It was a life of conflict, but also a life of hope. The Saviour would come again in like manner as he had gone. The spiritual victory, already won, would be perfected by a final victory in every realm.
=(2) The Missionary Preaching of Paul.=--The gospel of the early preachers was a glorious message. It was a piece of glad tidings, such as the world had never known. Yet even greater things were in store; even more wondrous mysteries were to be revealed. They were revealed especially through the instrumentality of the apostle Paul. The gospel had been preached from the beginning, but much of its deeper meaning was reserved for Paul.
(a) Truth and Error.--In the teaching of Paul, truth became plainer by being contrasted with error. The original apostles had really been trusting in the atonement of Christ for salvation; but now that trust became plainer and more explicit by being contrasted with works of the law. The original apostles had really grasped the inner significance of Jesus as the fulfillment of the Old Testament; but now that significance became still plainer by the contrast with Pharisaic legality. Now at length the death and resurrection were represented sharply and clearly as great representative acts in which the believer shares through faith. The original apostles were not overwhelmed and confused by the new revelation; they recognized the grace of God. Their perfect agreement with Paul exhibited the unity of the apostolic gospel.
