Gospel Matthew 9:14-17
The disciples of John approached Jesus and said, “Why do we and the Pharisees fast much, but your disciples do not fast?” Jesus answered them, “Can the wedding guests mourn as long as the bridegroom is with them? The days will come when the bridegroom is taken away from them, and then they will fast. No one patches an old cloak with a piece of unshrunken cloth, for its fullness pulls away from the cloak and the tear gets worse. People do not put new wine into old wineskins. Otherwise the skins burst, the wine spills out, and the skins are ruined. Rather, they pour new wine into fresh wineskins, and both are preserved.” 
Reflection The practice of fasting was a way of preparing for something that was coming, to make you more aware of it, more attentive to what it really meant. And so, in a sense, the Old Testament was an evolution of understanding of religion that was leading to the fullness that came in Jesus. And it's so radically different. And the radical difference is the way in which God deals with us, in our weaknesses.
He is not demanding sacrifices any longer. He demands only that we accept mercy. And you can't put mercy into the same category as you can, rules and regulations and punishment. What Jesus is trying to teach the disciples of John, is how radical a change is about to take place. Please ponder this reflection and I will close with the prayer.
Closing Prayer Father, it's difficult for us to fathom the fullness of your message. It goes against so much that's in our own broken human nature, where we feel revenge and we feel that it's difficult to forgive people. But open us to the fullness of who you are, so that it would be a way of being in the world that'll be so different that the old will seem absolutely useless, and the new will bring us life. And we ask this in Jesus’ name, Amen.
