This. You've got scads of biblical and mythological names -- Chris might seem like an especially big "ouch, obvious", but I don't think from an outside view it's any worse than other myth/religion/folklore connected names, like Joshua, Matthew, Lugh and Lleu, and even that Marth/Mars deal.

And agreed with the idea that it could easily be intentional- there are a whole lot of clear connections to the name-roots going on across FE, and to a culture that isn't predominately Christian, it probably doesn't feel much different than a Westerner might feel slapping "Shiva" or something like that on a character.
