Jesus' words to Peter, "On this rock I found my community," indicated that he was seeking to build a structure that would endure, because it was built on the solid rock of reality and in accordance with the divine purpose. For this reason he keenly appreciated the importance of building on the right foundations and with the right material. The major part of his time and energy was devoted to preparing these materials. Hence his intense interest in the saving and remaking of men and women. Peter, the rock, was typical of the social citizens that he was seeking to develop and out of which he planned to build his new society. Like Zoroaster, Confucius, and Gautama Buddha, Jesus was not content with presenting merely an abstract social programme. He was eager to incarnate it in flesh and blood, so that men could see it with their eyes and participate in it. With all the enthusiasm and energy of his kinetic personality, he went about laying the foundations for the new society. This aim alone explains why at first he left Galilee, went down into Judea, and allied himself with that courageous herald of the new social order, John the Baptist. When the opposition of the Jewish leaders and the cruel relentlessness of Herod Antipas closed the doors of Jerusalem and Judea to Jesus he returned to Galilee but not to Nazareth. He chose instead, as the scene of his future work, the great Jewish metropolis of Capernaum. Its choice as the centre of his public activity is exceedingly significant. Jesus was by birth and training a peasant. He always felt most at home among the tree-clad hills. City life had none of the attractions for him that it had for Paul, the cosmopolitan. Going to a great city was for Jesus a daring adventure. He went to Capernaum because it was the largest centre of Jewish population in northern Palestine. As the present ruins indicate, it extended for four or five miles along the northern shores of the Sea of Galilee, from the point where the Jordan enters the lake on the north to the borders of the plain of Genneseret to the northwest. Across the Jordan was Bethsaida, and a few miles to the north, at the head of a rocky gorge, was Chorazin, another of the many populous suburbs of the greater Capernaum. In this huge metropolis were crowded "the lost sheep of the house of Israel" whom Jesus came to seek and to save. Jesus went down into the sickness and crime-infected slums of Capernaum to transform them and to make them the homes of happy, co-operating men and women. In that large, typical suburban centre he aimed to establish the fraternal community that was to be the corner-stone of the new social order that he hoped would ultimately include "all the nations of the world."
