John Calvin on 2 Thessalonians 3:5

As, however, he states here in a summary manner the things that he knew to be most necessary for Christians, let every one make it his endeavor to make proficiency in these two things, in so far as he desires to make progress towards perfection. And, unquestionably, the love of God cannot reign in us unless brotherly love is also exercised. Waiting for Christ, on the other hand, teaches us to exercise contempt of the world, mortification of the flesh, and endurance of the cross. At the same time the expression might be explained as meaning, the patience of Christ — that which Christ’s doctrine begets in us; but I prefer to understand it as referring to the hope of ultimate redemption. For this is the only thing that sustains us in the warfare of the present life, that we wait for the Redeemer; and farther, this waiting requires patient endurance amidst the continual exercises of the cross.

2 Thessalonians 3:6-10

6. Now we command you, brethren, in the name of our Lord Jesus Christ, that ye withdraw yourselves from every brother that walketh disorderly, and not after the tradition which he received of us.

6. Praecipimus autem vobis, fratres in nomine Domini nostri Iesu Christi, ut vos subducatis ab omni fratre, qui inordinate ambulet, et non iuxta institutionem, quam accepit a nobis.

7. For yourselves know how ye ought to follow us: for we behaved not ourselves disorderly among you;

7. Ipsi enim scitis, quomodo oporteat nos imitari, quia non inordinate egimus inter vos:

8. Neither did we eat any man’s bread for nought; but wrought with labour and travail night and day, that we might not be chargeable to any of you:

8. Neque gratis panem comedimus a quoquam, sed cum labore et sudore nocte dieque facientes opus, ne cui vestrum graves essemus.

9. Not because we have not power, but to make ourselves an ensample unto you to follow us.

9. Non quod non habeamus potestatem, sed ut nos ipsos exemplar proponeremus vobis ad imitandum vos.

10. For even when we were with you, this we commanded you, that if any would not work, neither should he eat.

10. Etenim quum essemus apud vos, hoc vobis praecepimus, ut, qui laborare non vult, is neque comedat.
