Luke transmits to us the same saying, but at the end he adds: "And no one after drinking old wine desires new; for he says, 'The old is good'" (Lk 5:39). There do seem to be good grounds for interpreting this as a word of understanding for those who wished to remain with the "old wine." (page 181)
Now, to anyone who claims this is going back to before the Council, I challenge them to find this kind of interpretation back then (by a conservative that is). One of the things that bothers so many progressives in the Church is that both Pope John Paul II and the current pope defy the limitations of the labels placed upon them--they are seekers of the Truth, and not some ideology created in their own image and likeness rather than the image and likeness of the one true God. Another reason, why this is truly a "great book"...
