The three apostles

Jesus did not take Peter, James, and John with him up to the mount of the transfiguration because they were in any sense better prepared than the other apostles to witness what happened, or because they were spiritually more fit to enjoy such a rare privilege. Not at all. He well knew that none of the twelve were spiritually qualified for this experience; therefore did he take with him only the three apostles who were assigned to accompany him at those times when he desired to be alone to enjoy solitary communion.[1]
