BE CAREFUL IN JUDGING OTHERS.
How, then, did Christ say, All things that I have heard from the Father I have made known to you,[1] except in this way, that what he was certainly going to accomplish through the Holy Spirit, he spoke to us as if he had already accomplished it? Therefore, whenever we hear that one who believes in Christ will not be judged, we are to understand that he will not be condemned. The word judged is used in place of condemned, as where the apostle says, Let not him who does not eat condemn him who eats,[2] that is, let him not think evil of him. And the Lord says, Do not judge that you may not be judged.[3] He does not take from us the power to judge, since the prophet also declares, If you truly love justice, judge right things, O sons of men. And the Lord says, Judge not according to personal considerations, but render a just judgment.[4] But, in that passage where he forbids judging, he admonishes us not to condemn a person whose purpose is hidden from us, or when we do not know how a person will turn out later on. Accordingly, when he said, He shall not come to judgment,[5] he meant that he will not come to damnation. And in saying but he who does not believe is already judged, he meant that such a person stands already condemned in the foreknowledge of God, who knows what is in store for nonbelievers.
