For even. — The sequence of thought is a little difficult, but it seems best to regard this “for” as connecting its sentence, not with 2 Thessalonians 3:9, but rather with 2 Thessalonians 3:6. It does not give the reason why St. Paul and his companions worked: “because we strictly enjoined you to work, and therefore could not be idle ourselves.” Rather, it justifies the reiteration of the command: “We do not hesitate to command you now to repress this disorderly conduct, so contrary to the example set you; for, in fact, when we were with you we used to lay down this law.” So Theodoret takes it: “It is no new thing that we write to you.”
We commanded. — The tense in the original is that of constant re-assertion, which brings out once more the thorough grounding which the Apostles gave at once to their converts. (See Note on 2 Thessalonians 3:6 : “the tradition;” also the Note on 2 Thessalonians 2:5.) The same definite precept is referred to in 1 Thessalonians 4:11.
If any would not work. — The word “would” stands for “is not willing,” “refuses.” To any weakness or incapacity for work, except in himself, St. Paul would be very tender; the vice consists in the defective will. The canon (in the original) is laid down in the pointed form of some old Roman law like those of the Twelve Tables: “If any man choose not to work, neither let him eat.” It does not mean, “let him leave off eating,” putting it to the man’s own conscience to see the necessary connection between the two things (Genesis 3:19); but, “let him not be fed.” The Thessalonians are not to be misled into a false charity: giving food in Christ’s name to persons who are capable of working and able to get work, and are too indolent to do so. The support which is here forbidden to be given to these disorderly persons might come either direct from the private liberality of individuals, or from some collected church fund administered by the deacons. It does not seem at all impossible that this Thessalonian Church, which St. Paul himself declares to have taken the churches of Judaea for a model (1 Thessalonians 2:14), may have copied its model in adopting some form of communism, or, at any rate, some extensive use of the agapè which we see to have been in use at Corinth, established by the Apostle at the very time of writing this Letter (1 Corinthians 11:21). Such a supposition would give much more point to St. Paul’s canon, as well as to other phrases in both these Epistles, and would enable us to understand better how this discipline could be actively enforced. That the ordinary agape was a matter of considerable importance to the poorer classes is evident from 1 Corinthians 11:22.
