Under what authority did Titus conduct himself in Crete?
Under ordained authority as a presbyter flowing from Christ, to the apostles, to the presbyters and to others, to whom (conditional) obedience is enjoined as those "over you" in the Lord. (Heb. 13:17) Whom is over you in the Lord that you are to obey? Under what authority did the Scribes and Pharisees sit in authority in the seat of Moses? Just make your argument, which has been already refuted.
