comes from two Greek words, the one a preposition meaning “together” and the other a noun meaning “sight.” In Biblical studies it is used to refer to the Gospels of Matthew, Mark, and Luke that so often “see together” the way that they tell the story of Jesus, even when the Gospel of John often goes its own way. A related term, synopsis, is used for a book that lays out the the four Gospels in such a way that you can easily compare parallel, or closely parallel passages.
