Charles Ellicott Commentary Romans 3:22

"even the righteousness of God through faith in Jesus Christ unto all them that believe; for there is no distinction;" — Romans 3:22 (ASV)

A further definition of the nature of the righteousness so given to the Christian by God; it is a righteousness that has its root in faith, and is coextensive with faith, being present in every believer.

By faith of Jesus Christ—that is, by faith which has Christ for its object, “faith in Christ.” “Faith” in St. Paul’s writings implies an intense attachment and devotion. It has an intellectual basis, necessarily involving a belief in the existence, and in certain attributes, of the Person for whom this faith is held; but it is moral in its operation, a recasting of the whole emotional nature in accordance with this belief, together with a consequent change in character and practice. (See Excursus B: On the Meaning of the word Faith.)

And upon all.—These words are missing from the best manuscripts and should be omitted.

For there is no difference.—The righteousness that God gives is given to all who believe, without any distinction of Jew or Gentile; for all equally need it, and it is free equally to all.
