Verse 3. Giving no offence in any thing. We the ministers of God, 2 Co 6:1. The word rendered offence means, properly, stumbling; then offence, or cause of offence, a falling into sin. The meaning here is, "giving no occasion for contemning or rejecting the gospel; and the idea of Paul is, that he and his fellow-apostles so laboured as that no one who saw or knew them should have occasion to reproach the ministry, or the religion which they preached; but so that in their pure and self-denying lives, the strongest argument should be seen for embracing it. Comp. Mt 10:16; 1 Co 8:13; 10:32,33.

See Barnes "Php 2:16"; See Barnes "1 Th 2:10, See Barnes "1 Th 5:22".

How they conducted [themselves] so as to give no offence he states in the following verses.

That the ministry be not blamed. The phrase, "the ministry," refers here not merely to the ministry of Paul, that is, it does not mean merely that he would be subject to blame and reproach, but that the ministry itself which the Lord Jesus had established would be blamed, or would be reproached by the improper conduct of any one who was engaged in that work. The idea is, that the misconduct of one minister of the gospel would bring a reproach upon the profession itself, and would prevent the usefulness and success of others, just as the misconduct of a physician exposes the profession to reproach, or the bad conduct of a lawyer reflects itself in some degree on the entire profession. And it is so everywhere. The errors, follies, misconduct, or bad example of one minister of the gospel brings a reproach upon the sacred calling itself, and prevents the usefulness of many others. Ministers do not stand alone. And though no one can be responsible for the errors and failings of others, yet no one can avoid suffering in regard to his usefulness by the sins of others. Not only, therefore, from a regard to his personal usefulness should every minister be circumspect in his walk, but from respect to the usefulness of all others who sustain the office of the ministry, and from respect to the success of religion all over the world. Paul made it one of the principles of his conduct so to act that no man should have cause to speak reproachfully of the ministry on his account. In order to this, he felt it to be necessary not only to claim and assert honour for the ministry, but to lead such a life as should deserve the respect of men. If a man wishes to secure respect for his calling, it must be by living in the manner which that calling demands, and then respect and honour will follow as a matter of course. See Calvin.
