Today's Gospel was the one about the wineskins, old and new. The priest explained that new wine is still fermenting--like those "friendship bread" starters that were the rage some years ago. You had to keep transferring a bit of the gooey mass into another zipper bag because it kept growing. Forget to do it, and you had a gooey explosion all over the kitchen! So, new zipper bags for bread starter, new wineskins for new wine.
But, as Jesus poignantly commented, "No one who has been drinking old wine wants new. He says, 'The old is good.' " Trying the new wine of the Gospel is a bit of a risk!
