Palamas taught that the truth is a person, Jesus Christ, a form of objective reality. In order for a Christian to be authentic, he or she must experience the Truth (i.e. Christ) as a real person (see hypostasis). Gregory further asserted that when Peter, James and John witnessed the Transfiguration of Jesus on Mount Tabor, that they were in fact seeing the uncreated light of God; and that it is possible for others to be granted to see that same uncreated light of God with the help of certain spiritual disciplines and contemplative prayer, although not in any automatic or mechanistic fashion.
