John, Saint: one of the original 12 disciples, or apostles, of Jesus Christ. A Jew, his name in Greek is Johanan, which means “YHWH has been gracious.” Jesus also called him a “Son of Thunder” (Mark 3:17). He is also known as “John the Beloved” or “The disciple whom Jesus loved.”

John the Baptist: born miraculously as the son of the priest Zechariah and his wife Elizabeth, the cousin of Mother Mary, mother of Jesus. A staunch ascetic and denouncer of religious hypocrisy, he baptized Jesus and others at the river Jordan, while announcing that he was only the forerunner of Christ who would baptize with fire. Jesus referred to him as the reincarnation of Elijah (Matt 11.13–14). He was executed by Herod Antipas.

John, Gospel of: one of the four Gospels of the New Testament. The Gospel of John is dated about 90 C.E., about thirty years after the writing of the synoptic Gospels (Mark, Matthew and Luke). The most mystical gospel, it distinguishes itself sharply from the three synoptic gospels by its cosmological scale and its identification of Jesus as the Logos.

Jung, Carl (1875-1961): the Swiss-German psychoanalyst who, with Sigmund Freud, was instrumental in bringing psychology to explore the role of the unconscious.
