We are Christian, we use R&S. Some, not all, lessons say things like "God wants us to do good things, like write in complete sentences." (Not an exact quote). For the most part, any Bible references in exercises are Bible stories. Some don't mention God, so if you don't read the Bible, your child won't know it is a Bible story. As far as, too much writting, I bought the work sheets this year. It is cutting down on some work. If there is a work sheet, we use that; if not, we do as much as we can orally.
