John IV pope (
December 24,
640 -
October 12,
642), was a
Dalmatian by birth, and succeeded
Pope Severinus after the papal chair had been vacant four months. While he adhered to the repudiation of the
Monothelism[?] doctrine by Severinus, he endeavoured to explain away the connection of
Pope Honorius I with the heresy, especially defending him against emperor
Constans II.
- preceeded by Pope Severinus (640)
- succeeded by Pope Theodore I (642-649)
