Honestly, I doubt the paps are going to snap pics of the Wales family attending church. It may be something neither Will nor Kate felt strongly about doing while they were in their twenties, but once they had children they became, quietly, more observant about. We've heard they have a close relationship with Edward & Sophie, who are known to be faithful, so it's entirely possible that the Wales', like the Wessexes, just quietly go about their way with going to church and teaching their children about the Christian faith.
