Okay, I've got a smallish dilemma, and I thought I'd solicit the wisdom of the Orgahs.

In a nutshell: My mom is a Christian Scientist, and wants my kids to go to a CS Sunday School, such as I attended when I was a kid. Benefits:
  • Focus on scripture with a minimum of proselytizing
  • No priests, deacons, ministers or official clergy of any sort; entirely lay-ministered
  • Very nice people

Drawbacks:
  • Non-Nicene theology
  • I have to sit through the main service, which is both boring and (to my mind) misguided
  • My family has historically been Episcopalian
  • Long drive

Now, she's been the best grandma anyone could ask for, devoting a great deal of time and effort to the kids. I don't want to irritate her in any way, 'cause she has been the single-most supportive member of our extended family. However, I cannot kindle to CS theologically, and I don't particularly want my kids going that route. I'd rather take my kids (and myself) to the local Episcopal church on Sundays. But I don't want to offend the best relative I have.

Ideas?
