Bede : Beloved, you act faithfully in whatever you work for the brethren, etc. You act faithfully, he says, as if he said: Just as you are truly faithful, so you act, showing your faith by your works. — Commentary on the Catholic Epistles Oecumenius : Dearly beloved, you faithfully do whatever you work for the brothers and for the guests, who have borne witness to your love in the sight of the Church; if you have led them to God worthily, you will benefit. For they went forth for His name, taking nothing from the Gentiles. "you faithfully do," this is what befits a faithful man. — Commentary on 3 John
