Whosoever shall receive one of such children in my name, receives me: and whosoever shall receive me, receives not me, but him that sent me.
All Commentaries on Mark 9:37 Go To Mark 9
Tertullian of Carthage
AD 220
Do not receive without prayer one who enters your house, especially if that one is a stranger, lest he turn out to be an angelic messenger. Do not offer your earthly refreshments prior to receiving heavenly refreshment.
