Today's Gospel always reminds me of the time I first encountered the possibility of error in the Bible (not doctrinal error, mind you, just inexact information). I was about nine, and was the proud and hope-filled possessor of some seed packets, purchased from the local "dime" store. Among the flowers I hoped would grow in our freshly prepared patch of backyard were zinnias. I ripped open the packet and poured the seeds into my hand: hundreds of tiny black dots settled into my palm. And I remembered the words of the Holy Gospel, "the mustard seed is the smallest of all seeds."
I had seen mustard seeds (in those little acrylic bubbles). I looked again at the seeds in my hand. These had to be the smallest of all seeds.
Faced with the obvious fact that Jesus was plain wrong about seeds, I was in a quandary. Did Jesus, who was all-knowing, not know about zinnias? Was the Bible wrong about other things besides the relative sizes of seeds? Did any grown-ups know about this? I piously decided to ignore the discrepancy, but every time I hear this Gospel, well... now you know!
