And no man puts new wine into old wineskins: else the new wine does burst the wineskins, and the wine is spilled, and the wineskins will be ruined: but new wine must be put into new wineskins.
All Commentaries on Mark 2:22 Go To Mark 2
Tertullian of Carthage
AD 220
He has prescribed for his new disciples of the New Testament a new form of prayer. For this it was fitting that new wine be stored in new wine skins and that a new patch be sewed upon a new garment. What had prevailed in days gone by was either abolished, like circumcision, or completed, like the rest of the law, or fulfilled, like the prophecies, or brought to its perfection, like faith itself. Everything has been changed from carnal to spiritual by the new grace of God which, with the coming of the gospel, has wiped out the old era completely.
