Resolution isn't that great but when zoomed in I can make out founder belief, follower belief, follower belief 2, enhancer belief and bonus belief and a list of SP-like effects. From this I deduce that at certain points (presumably linked to these 'faith points') they can be used to increase the benefits gained from the religion.
As for espionage, I see the words establishing surveillance, counter intelligence and rigging elections
EDIT: I also notice bonus belief says "Byzantines only", add another new civ to the list.
