"Just as I urged you upon my departure for Macedonia, to remain on at Ephesus so that you would instruct certain people not to teach strange doctrines, nor to pay attention to myths and endless genealogies, which give rise to useless speculation rather than advance the plan of God, which is by faith, so I urge you now. But the goal of our instruction is love from a pure heart, from a good conscience, and from a sincere faith" (1 Tim 1:3-5).
