Colossians 1:7

As ye also learned of Epaphras - Epaphras was then with Paul. Philemon 1:23. He had probably been sent to him by the church at Colossae to consult him in reference to some matters pertaining to the church there. It is evident from this, that Epaphras was a minister of the church at Colossae, though there is no evidence, as has been often supposed, that he was the founder of the church. The apostle here says, that they had learned from Epaphras the true nature of the gospel, and he designs undoubtedly to confirm what he had taught them in opposition to the teachings of errorists; see the Introduction, Section 4. He had doubtless conferred with Epaphras respecting the doctrines which he had taught there.

Our dear fellow-servant - This shows that Paul had contracted a strong friendship for Epaphras. There is no reason to believe that he had known him before, but his acquaintance with him now had served to attach him strongly to him. It is possible, as has been conjectured (see the Introduction), that there was a party in the church at Colossae opposed to Epaphras and to the doctrines which he preached, and if this were so, Paul’s strong expression of attachment for him would do much to silence the opposition.

Who is for you a faithful minister of Christ - “For you,” when he is with you, and in managing your interests here.
