A long time ago I had an idea for a Redemption set that I would love to see made if I ever had the chance. The idea was for a set based on Spiritual Warfare, and it would include Prayers and the Armor of God on the good side and sins on the evil side. Most of the cards would be place and/or set aside cards that help support the battle or work over the whole game rather than winning a single battle, much like how sins will break people slowly and prayers will strengthen the saints.
Then much more recently a friend of mine and I brought the idea a little more to life, and while I love the ideas, (although this is from a T2 player, I'm not sure how useful the strategies would be in T1) my biggest concern is Theological.
I wanted to use the Seven Deadly Sins as base for the sins on the evil side, since there are Seven Deadly Sins and Seven Evil Brigades, and since they are all sins that shouldn't be a problem, however when I had the idea of having cards reference those 7 cards (or sins) and no others, I came up with the identifier "Deadly Sin", here is where my theological concern comes in:
Since the Seven Deadly Sins are never mentioned in a single list in the Bible, would there be an issue with using a "Deadly Sin" identifier?
For reference the current version of the Seven Deadly Sins was made in AD 590 by Pope Gregory I and consists of Lust, Gluttony, Greed, Envy, Sloth, Wrath and Pride.
