Scriptures???

It all began a couple of months ago when we were visiting my mom. Bowen came running in the room and told me with much excitement that he had found some scriptures. He loves Thomas the Tank Engine, and when you buy a new train, it comes with a little fold-out pamphlet of other Thomas trains you can collect. For some reason, he thinks they are called scriptures. He has several sets of "scriptures" in his Thomas tupperware, and he reads them often!
