JOHN, PRESTER, a supposed king and priest of a mediaeval kingdom in the interior of Asia; converted to Christianity by the Nestorian missionaries; was defeated and killed in 1202 by Genghis Khan, who had been tributary to him but had revolted; he was distinguished for piety and magnificence.

JOHN, ST., the Apostle, the son of Zebedee and Salome, the sister of the virgin Mary; originally a fisherman on the Galilaean Lake; after being a disciple of John the Baptist became one of the earliest disciples of Christ; much beloved and trusted by his Master; lived after His death for a time in Jerusalem, and then at Ephesus as bishop, where he died at a great age; he lived to see the rise of the Gnostic heresy, against which, as a denial that Christ had come in the flesh, he protested with his last breath as an utter denial of Christ; he is represented in Christian art as either writing his Gospel, or as bearing a chalice out of which a serpent issues, or as in a caldron of boiling oil.

JOHN, THE GOSPEL ACCORDING TO, the fourth Gospel, of which tradition alleges St. John was the author, and which is presumed to have been written by him at Ephesus about A.D. 78; its great design is to bear witness to the Son of God as having come in the flesh, as being not an ideal, therefore, but a real incarnation, and as in the reality of that being the light and life of man; whereas the scene of the other Gospels is chiefly laid in Galilee, that of John’s is mostly in Judea, recording, as it does, no fewer than seven visits to the capital, and while it portrays the person of Christ as the light of life, it represents him as again and again misunderstood, even by those well disposed to Him, as if the text of his Gospel were “the light shineth in darkness, and the darkness comprehendeth it not”; the authenticity of this Gospel has been much debated, and its composition has by recent criticism been referred to somewhere between A.D. 160 and 170.

JOHN BULL, a humorous impersonation of the English people, conceived of as well fed, good natured, honest hearted, justice loving, and plain spoken.

JOHN OF LEYDEN, originally a tailor; attained great power as an orator; joined the Anabaptists, and in 1534 established at Muenster, in Westphalia, a society based on communistic and polygamic principles; but the bishop of Muenster interfered, and next year John was put to death with great cruelty (1509-1536).
