1 Corinthians 4:17
For this reason I have sent to you Timothy, my son whom I love, who is faithful in the Lord. He will remind you of my way of life in Christ Jesus and how I teach everywhere in every church — Timothy (Timotheos, 'honoring God') is Paul's representative, sent to reinforce the apostle's message. 'Faithful in the Lord' means Timothy is trustworthy, aligned with Christ. He will 'remind' (anamimnesko) the Corinthians of Paul's 'way of life' (hodoi) and consistent teaching. Consistency across churches (not custom-tailored to please each congregation) is mark of authentic apostolate.
