8 But if it is perfect madness to hold such a view (for it is Christ always that justifies the ungodly, by changing his ungodliness into Christianity; it is from Christ always that faith is received, Christ is always the origin of the regenerate and the head of the Church), what weight, then, will those words have, which thoughtless readers value by their sound, without inquiring what their inner meaning is? For the man who does not content himself with hearing the words with his ear, but considers the meaning of the phrase, when he hears, "What we look to is the conscience of the giver, that it may cleanse the conscience of the recipient," will answer, The conscience of man is often unknown to me, but I am certain of the mercy of Christ: when he hears, "He who receives faith from the faithless receives not faith, but guilt," will answer, Christ is not faithless, from whom I receive not guilt, but faith: when he hears, "Everything consists of an origin and root; and if it have not something for a head, is nothing," will answer, My origin is Christ, my root is Christ, my head is Christ.
When he hears, "Nor does anything well receive second birth, unless it be born again of good seed," he will answer, The seed of which I am born again is the Word of God, which I am warned to hear with attention, even though he through whom I hear it does not himself do what he preaches; according to the words of the Lord, which make me herein safe, "All whatsoever they bid you observe, that observe and do; but do not ye after their works: for they say, and do not." When he hears, "What perversity must it be, that he who is guilty through his own sins should make another free from guilt!" he will answer, No one makes me free from guilt but He who died for our sins, and rose again for our justification.
For I believe, not in the minister by whose hands I am baptized, but in Him who justifies the ungodly, that my faith may be counted unto me for righteousness.
