Inside Calvin's Church - HT:Justin Taylor
In case we over romanticize Martin Luther here's Carl Trueman on 9.5 Theses on Martin Luther against the self indulgences of the modern church.
But Justin Taylor offers us reasons why we all need a friend like Martin Luther.
If you haven't seen Luther you seriously need to, i didn't expect much but found it to be absolutely brilliant. (i think you can pick it up on ebay for about £4)
