Golly! He IS bad, isn't he?
It is generally true that when one wishes to attack Christianity in-general it is the Church they target, not just because of its antiquity but because of its claim of catholicity. The adversary and his followers know what their enemy is, and they know that Christian unity is the most dangerous aspect of it. This was true right from the beginning; for example the adversary did not tempt them both at once, he did it individually and for a reason. Division is his strength, not ours.
