"There can be few worse impediments to the study of divine truth than for a student, either from birth and upbringing, by the false teaching of others or for worldly advantage, to be ensnared into a vigorous sect before he has had the chance to develop independent, candid, and mature judgment of his own. How many turn aside in this way for the lure of wealth, honors, or esteem! The touchstone and measure of all truth for such enslaved men becomes the teachings of the sect, and all of their studies are guided by no other pole-star than a horror of falling unawares into the opinions of any other sect but their own! They are terrified of receiving truth and light from other men at the expense of their lucrative errors! And all the while they consider themselves to be most learned, intelligent, prudent, and pious of men; judging all of these things by the yardstick of their sect, that is, within the blinkered vision of a worthless faith. The natural result is seen in those eternal squabbles, law-suits, hatreds, and quarrels which are so far removed form Christian meekness and charity."
John Owen, Epistle to the Reader, Biblical Theology, xxxi
