Well, I did one run in 1-4 on NG+ with two more Blue Phantoms, on Pure Black World Tendency and I got 500K souls from it, I guess you're just having bad luck farming :(
200K souls lost is quite a bit, but just wait until you lose 400K souls :P

Talisman of God are found on:
4-1 Treasure (Before first fog, right side under tree)
5-1 Treasure (From Morning Star location, lower bridge across chasm)
5-x Vendor (5,000s)
Also, there is a talisman that will allow you to cast both spells and miracles at the same time, it's the Talisman of Beasts, but you'll only get it if you defeat Black Phantom Scirvir on 2-2 in Pure Black World Tendency, and mind you, it's the hardest NPC Black Phantom in the game >_
