It is the same attitude — the Pope continued, referring to the day’s passage from Mark (2:18-22) — that “Jesus teaches in the Gospel, when the doctors of the law rebuke him because his disciples do not fast: ‘This is how it’s always been done. Why don’t your [disciples] fast?’. And Jesus responds with this principle of life: ‘No one sews a piece of unshrunk cloth on an old garment; if he does, the patch tears away from it, the new from the old, and a worse tear is made. And no one puts new wine into old wineskins; if he does, the wine will burst the skins, and the wine is lost, and so are the skins; but new wine is for fresh skins’”.
In essence, Francis asked, “what does this mean, that the law has changed? No!”. It means, rather, “that the law is at the service of man, that it is at the service of God, and for this reason man must have an open heart”. The attitude of those who say “this is how it’s always been done…”, in reality, is born from “a closed heart”. Instead, however, “Jesus told us: ‘I will send the Holy Spirit and he will lead you to the full truth”. Thus, “if your heart is closed to the newness of the Holy Spirit, you will never reach the full truth”. Additionally, “your Christian life will be a half and half life, a patched up life, mended with new things but on a structure that is not open to the Lord’s voice: a closed heart, because you are not capable of changing the wineskins”.
