Tertullian,
Ante-Nicene Fathers Vol. IV, Tertullian…
(1885)
“ If Christ is always, and prior to all, equally truth is a thing sempiternal and ancient. Let those therefore look to themselves, to whom that is new which is intrinsically old. It is not so much novelty as truth which convicts heresies. Whatever savours of opposition to truth, this will be heresy, even (if it be an) ancient custom. On the other hand, if any is ignorant of anything, the ignorance proceeds from his own defect. Moreover, whatever is matter of ignorance ought to have been as carefully inquired into as whatever is matter of acknowledgment received. ”
