I have decided to let the poll run for another week. Right now, it's a close race between G.K. Chesterton (13 votes) and the early Church Fathers (15 votes). I want to see if any of the options pull ahead as the clear favorite. If, by next Monday, it's still really close, then I'll either do them both at the same time, or one of the four options every 3 months.
Thank you all for voting. If you haven't voted yet....what's wrong with you?!?! Vote in the poll in my sidebar.
