'Minister of Christ' in the Bible

to be a minister of Christ Jesus to the Gentiles. I minister as a priest the gospel of God, in order that my offering of the Gentiles may become acceptable [to Him], sanctified [made holy and set apart for His purpose] by the Holy Spirit.

You learned it from [our representative] Epaphras, our beloved fellow bond-servant, who is a faithful minister of Christ on our behalf

If you point out these instructions to the brothers and sisters, you will be a good servant of Christ Jesus, constantly nourished [through study] on the words of the faith and of the good [Christian] doctrine which you have closely followed.
