I'm a former K teacher. When parents come in, I want them to read books their kids love, that take into account that kids attention spans are shorter in groups. Madeline is perfect.
I don't teach religion, but I teach about it. We talk about the word Pastor when we talk about MLK. We'll admire a picture of a church when it comes up in a book. I have no problem with the line in this context.
Also, despite having read the book many times, I can't remember the phone numbers, so if you read it as Dayton or Danton, even if it's not how I'd pronounce it, I wouldn't remember the spelling so I wouldn't have any idea if you were right or wrong.
Have fun!
