“No man also seweth a piece of new cloth on an old garment: else the new piece that filled it up taketh away from the old, and the rent is made worse.”
Mark 2:21 — Greek Interlinear
Church Fathers on Mark 2:21
For the disciples of John being in an imperfect state, continued in Jewish customs.
But it may be thought that He added Pharisees, because they joined with the disciples of John in saying this to the Lord, whilst Matthew relates that the disciples of John alone said it: but the words which follow father shew that those who said it spoke not of themselves, but of others.
But John did not drink wine and strong drink, because he who has no power by nature, obtains more merit by abstinence. But why should the Lord, to whom it naturally belonged to forgive sins, shun those whom he could make more pure, than those who fast? But Christ also fasted, lest He should break the precept, 'He ate with sinners,' that thou mightest see His grace, and acknowledge His power.
