The Bells of Saint John

The end of this month Doctor Who will return and the title of that first new episode will be “The Bells of Saint John.” Regular readers will know that this is a blog which regularly focuses on religion and Doctor Who. But it is also a blog where Johns who might be prefixed by “Saint” also get a particularly large amount of attention (whether the supposed author of the Gospel of John, or the author of Revelation, or John the Baptist in Jewish, Christian, or Mandaean sources).

And so it seems like a natural place for the question to be asked: Why do you think this episode is called “The Bells of Saint John”? And is it significant that it isn't written, as one might expect, with the common abbreviation as “The Bells of St. John”?
