John Gill Commentary Colossians 4:17

"And say to Archippus, Take heed to the ministry which thou hast received in the Lord, that thou fulfil it." — Colossians 4:17 (ASV)

And say to Archippus
A name common among the Grecians. This person the apostle calls his fellow soldier, in (Philemon 1:2) and who was now the minister of the Gospel at Colosse, his fellow minister, or co-pastor Epaphras, being at Rome, and a prisoner there; though by some he is said to be the first bishop of the Laodiceans, but it seems most likely that he now resided at Colosse, and was their minister: who being negligent in his office, they are called upon to say to him,

take heed to the ministry which you have received in the Lord ,
that you fulfil it .
The "ministry" he had, was not that of the office of a deacon, as some have thought, but of a preacher of the word; and this he had "received" gifts for, and was called to it, and installed in it; and that "in", and "by the Lord" himself, and to whom he was accountable for it: and therefore it was incumbent on him to "fulfil it"; by constantly preaching the word, and faithfully administering the ordinances; by defending truth, detecting error, reproving vice, visiting the sick, and comforting the feeble minded; taking heed in all things to himself and doctrine, that he feed the whole flock of God with wholesome food; and, as a wise and faithful steward, give to everyone their portion of meat in due season:

hence it appears, that when ministers are negligent in the discharge of their duty, the church has a power to admonish and exhort them to a diligent performance of it.
