For Herod himself had sent forth and laid hold upon John, and bound him in prison for Herodias' sake, his brother Philip's wife: for he had married her.
All Commentaries on Mark 6:17 Go To Mark 6
Tertullian of Carthage
AD 220
Set aside for a moment the term “prison.” Just call it a temporary retirement. Even though the body is imprisoned, even though the flesh is confined, everything still remains open to the spirit. Walk back and forth, my spirit, not thinking of shady walks or long cloisters, but of the road that leads directly to God. As often as you shall walk in this way in the spirit, so often shall you find yourself not in prison.
