Claim Your Sainthood

All of us are saints, and accursed be he who does not call himself a saint and glory in it. If you believe the words of Christ, you are a saint as well as St. Peter and all the other saints; for dependeon it, Christ will not lie to you. Therefore if you do not say: I have as much as St. Peter and am as saintly as St. Peter, then you are ungrateful to your Lord Christ. My friend, I and you have in the past denied entirely too much. Do we want to do more of this? Nor is such glorying in our sainthood arrogance but modesty and thankfulness. In fact, he does not do it is slandering Christ and Baptism.
