'Faithful' in the Bible

To the saints and faithful brethren in Christ that are at Colossae: Grace to you and peace from God our Father.

even as ye learned of Epaphras our beloved fellow-servant, who is a faithful minister of Christ on our behalf,

All my affairs shall Tychicus make known unto you, the beloved brother and faithful minister and fellow-servant in the Lord:

together with Onesimus, the faithful and beloved brother, who is one of you. They shall make known unto you all things that are done here.
