I didn't hear the "miracle of sharing" interpretation this weekend.

I never have, actually. Hopefully it's on its way out.

I've always thought the quickest way to snuff it out would be to borrow the killer rebuttal I read about once. Approach the errant Father after the homily and ask him, in the presence of several parishioners in the glad-handing line:

"So, Father, you are saying that the 'miracle' was Jesus getting Jews to share?"

You'd never hear it again.
