'Faithful' in the Bible

to the saints, the faithful brothers and sisters in Christ, at Colossae. Grace and peace to you from God our Father!

You learned the gospel from Epaphras, our dear fellow slave -- a faithful minister of Christ on our behalf --

Tychicus, a dear brother, faithful minister, and fellow slave in the Lord, will tell you all the news about me.

I sent him with Onesimus, the faithful and dear brother, who is one of you. They will tell you about everything here.
