to the memory of Jesus.[2.16] In the absence of the lost Master, they obeyed the chief of the disciples, and above all, Peter. One day, when following their spiritual chiefs, the Galileans had climbed up one of the mountains to which Jesus had often led them, and they fancied that they saw him again. The air on these mountaintops is full of strange mirages. The same illusion which had previously taken place in behalf of the more intimate of the disciples, was produced again.[2.17] The whole assembly imagined that they saw the Divine spectre displayed in the clouds; they all fell on their faces and worshipped.[2.18] The feeling which the clear horizon of these mountains inspires is the idea of the immensity of the world and the desire of conquering it. On one of these neighboring points, Satan, pointing out with his hand to Jesus the kingdoms of the earth, and all the glory of them, it is said proposed to give them to him if he would fall down and worship him. On this occasion, it was Jesus who, from the top of these sacred summits, pointed out to his disciples the whole world, and assured them of the future. They came down from the mountain persuaded that the Son of God had commanded them to convert the whole human race, and had promised to be with them even to the end of the world. A strange ardor, a divine fire, took possession of them when they returned from these conversations. They looked upon themselves as the missionaries of the world, capable of effecting prodigious deeds. St. Paul saw many of those who were present at this extraordinary scene. At the expiration of twenty-five years, the impression on their minds was still as strong and as vivid as it was on the first day.[2.19]
