Re: Why Four Gospels?"
Oh I see.
The subject though your OP quite deep I think if followed out. As with Christ in Scripture, inexhaustable is probably a better term.
The four gospels have been related to the colors of the "door" of the Tabernacle. They are said to represent these four aspects (for lack of better term) of Jesus character and nature.
Purple: Matthew, his royalty as King of the Jews.
Scarlet: Mark, for His shed blood.
White: Luke, for His perfect righteousness.
Blue: John, for His deity.
The one curtain, or "the door" in which all who enter must pass has woven though out all these colors representative of the Person and work of Jesus. We who have the risen Savoir, the completed canon have so much given to us, what a blessing!
“Enter by the narrow gate; for wide is the gate and broad is the way that leads to destruction, and there are many who go in by it. 14 Because narrow is the gate and difficult is the way which leads to life, and there are few who find it." Matthew 7:13-14
