In the day when God shall judge the secrets of men by Jesus Christ according to my gospel.
Read Chapter 2
There are two thoughts inside a man which will accuse each other—the good and the evil. The good accuses the evil because it has denied the truth. The evil accuses the good because it has not done what it knows to be right. One who knows that the church is good and true but persists in heresy or schism will be judged guilty. Other thoughts will excuse, insofar as one has done what is expedient to do. He will say inwardly: “In my mind I have always thought it expedient to do what I have done. This was my faith.” He will have a better case, even though he will still have to be corrected, because his conscience will not accuse him on the day of judgment. This is how the secret things of men will be judged by Jesus Christ our Lord on the day of judgment. Commentary on Paul’s Epistles.
The aweinspiring countenance of the Judge will compel you to speak the truth. Even if you are silent, it will convict you. You will rise clothed either in your sins or in your just deeds. The Judge himself declared this.
Paul says the “secrets of men” and not the sins of men, in order to add to their fear…. For men sit in judgment on overt acts alone. If a secret deed of any one of us were brought into the open right now, in the midst of the church, what would we do except pray for death and have the earth swallow us up, rather than have so many witnesses of wickedness? Homilies on Romans
If God will judge the secrets of men … surely the God who will judge is he to whom belong both the law and that nature which is the rule for those who do not know the law. But how will he conduct this judgment? “According to my gospel,” says the apostle, “by Christ Jesus.” The law and nature are vindicated by the gospel and Christ.
