Therefore, being justified by faith, we have peace with God through our Lord Jesus Christ. Instead of the ἔχομεν of the Textus Receptus, an overwhelming preponderance of authority, including uncials, versions, and Fathers, supports ἔχωμεν ("let us have").
If this be the true reading, the expression must be intended as hortatory, meaning, apparently, "Let us appreciate and realize our peace with God which we have in being justified by faith." But hortation here does not appear in keeping with what follows, in which the results of our being justified by faith are described in terms clearly, corresponding with the idea of our having peace with God.
The passage as a whole is not hortatory, but descriptive, and "we have peace" comes in naturally as an initiatory statement of what is afterwards carried out. This being the case, it is a question whether an exception may not be allowed in this case to the usually sound rule of bowing to decided preponderance of authority with respect to readings.
That ἔχωμεν was an early and widely accepted reading there can be no doubt; but still it may not have been the original one, the other appearing more probable. Scrivener is of opinion that "the itacism of ω for ο, so familiar to all collators of Greek manuscripts, crept into some very early copy, from which it was propagated among our most venerable codices, even those from which the earliest versions were made."
