Books or Swords

A party of Coptic diplomats from our neighbor the other nation have crossed into our territory. They have an unusually large number of priests among them. Our advisors suspect that they are trying to make contact with other Christians to the north. The diplomats are worryingly tight-lipped on the subject of their purpose. Perhaps it is simply a religious matter, but what if they are attempting to gather allies against us? We would be beset on multiple fronts by fanatical infidels!
