As this first reading of the epistle had to take place in the common assembly of all, that is, in the Church, so it was surely read whenever there was desire or need for it.
In this one cannot fail to see an indication that the reading of the apostolic writings in church is an apostolic institution.
But why the adjuration? Clearly St. Paul foresaw that, because of certain fears or considerations, the pastors might not read this epistle before everyone.
To turn this aside, he adjures them in the name of the Lord to read it before all. By this he deprives of force every motive and reason the pastors might offer for not reading it publicly.
Read it before everyone, whatever may come of it. Such is the will of the Lord, and there is no need to reason about it. If you act otherwise, you will be alien to communion with the Lord.
No considerations could withstand such a threatening word. What exactly might have held the pastors back from public reading is not evident. There is no need to inquire into this.
It is enough to be satisfied with the thought that the Apostle either knew or certainly supposed something of the kind.
Was it not perhaps that the epistle contained rebukes which, of course, concerned certain known persons? Out of pity for them, or from fear of provoking them, the pastors might have refrained from reading the epistle before all.
True, everyone would have learned of them even without public reading. But for those rebuked, it would have been easier. Rejecting this plausible consideration, the Apostle adjures them to read the epistle before everyone.
Through this, the rebuke proved more effective for those rebuked and more useful for others. Those rebuked before all had to correct themselves before all.
All the others learned from this that such and such actions were blameworthy. By avoiding them, they were not doing something extraordinary, but fulfilling an apostolic directive.
Moreover, the adjuration protected the pastors. Those rebuked might say, “Why were they so shamed before all?” The pastors had something on which to rely: “We could not do otherwise. The Apostle adjured us by the Lord’s name.”
“So fearful were adjurations for the ancients! But alas, they are not so now, not so for us” (Theophylact).
An adjuration in the name of the Lord lays the strongest obligation to fulfill what one person asks of another. It binds the conscience by touching the living bonds of communion with the Lord.
It threatens their rupture in case of nonfulfillment. St. Chrysostom speaks at length about the importance of adjurations in the Lord’s name.
He gives an example of how precious in the eyes of the Lord Himself the fulfillment of a request under such an adjuration can be.
A slave woman, being in extreme distress, asked not her own mistress, but another noble lady, to intercede for her before her masters.
Having exhausted every persuasion, she finally added an adjuration: “Do not despise my request, lest Christ despise you on the day of judgment.”
Troubled by this adjuration, the lady hastened to the slave woman’s masters and arranged her matter. That very night she saw the heavens opened and Christ Himself.
St. Chrysostom concludes that she was counted worthy of such a vision precisely because she took the adjuration to heart.
