Romans 3:26

26.For a demonstration, (121) etc. The repetition of this clause is emphatical; and Paul resignedly made it, as it was very needful; for nothing is more difficult than to persuade man that he ought to disclaim all things as his own, and to ascribe them all to God. At the same time mention was intentionally made twice of this demonstration, that the Jews might open their eyes to behold it. — At this time, etc. What had been ever at all times, he applies to the time when Christ was revealed, and not without reason; for what was formerly known in an obscure manner under shadows, God openly manifested in his Son. So the coming of Christ was the time of his good pleasure, and the day of salvation. God had indeed in all ages given some evidence of his righteousness; but it appeared far brighter when the sun of righteousness shone. Noticed, then, ought to be the comparison between the Old and the New Testament; for then only was revealed the righteousness of God when Christ appeared.

That he might be just, etc. This is a definition of that righteousness which he has declared was revealed when Christ was given, and which, as he has taught us in the first chapter, is made known in the gospel: and he affirms that it consists of two parts — The first is, that God is just, not indeed as one among many, but as one who contains within himself all fullness of righteousness; for complete and full praise, such as is due, is not otherwise given to him, but when he alone obtains the name and the honor of being just, while the whole human race is condemned for injustice: and then the other part refers to the communication of righteousness; for God by no means keeps his riches laid up in himself, but pours them forth upon men. Then the righteousness of God shines in us, whenever he justifies us by faith in Christ; for in vain were Christ given us for righteousness, unless there was the fruition of him by faith. It hence follows, that all were unjust and lost in themselves, until a remedy from heaven was offered to them. (122)
