The Notes of a true Catholic.
[48.] This being the case, he is the true and genuine Catholic who loves the truth of God, who loves the Church, who loves the Body of Christ, who esteems divine religion and the Catholic Faith above every thing, above the authority, above the regard, above the genius, above the eloquence, above the philosophy, of every man whatsoever; who sets light by all of these, and continuing steadfast and established in the faith, resolves that he will believe that, and that only, which he is sure the Catholic Church has held universally and from ancient time; but that whatsoever new and unheard-of doctrine he shall find to have been furtively introduced by some one or another, besides that of all, or contrary to that of all the saints, this, he will understand, does not pertain to religion, but is permitted as a trial, being instructed especially by the words of the blessed Apostle Paul, who writes thus in his first Epistle to the Corinthians, |There must needs be heresies, that they who are approved may be made manifest among you:| as though he should say, This is the reason why the authors of Heresies are not forthwith rooted up by God, namely, that they who are approved may be made manifest; that is, that it may be apparent of each individual, how tenacious and faithful and steadfast he is in his love of the Catholic faith.
[49.] And in truth, as each novelty springs up incontinently is discerned the difference between the weight of the wheat and the lightness of the chaff. Then that which had no weight to keep it on the floor is without difficulty blown away. For some at once fly off entirely; others having been only shaken out, afraid of perishing, wounded, half alive, half dead, are ashamed to return. They have, in fact swallowed a quantity of poison -- not enough to kill, yet more than can be got rid of; it neither causes death, nor suffers to live. O wretched condition! With what surging tempestuous cares are they tossed about! One while, the error being set in motion, they are hurried whithersoever the wind drives them; another, returning upon themselves like refluent waves, they are dashed back: one while, with rash presumption, they give their approval to what seems uncertain; another, with irrational fear, they are frightened out of their wits at what is certain, in doubt whither to go, whither to return, what to seek, what to shun, what to keep, what to throw away.
[50.] This affliction, indeed, of a hesitating and miserably vacillating mind is, if they are wise, a medicine intended for them by God's compassion. For therefore it is that outside the most secure harbour of the Catholic Faith, they are tossed about, beaten, and almost killed, by divers tempestuous cogitations, in order that they may take in the sails of self-conceit, which, they had with ill advice unfurled to the blasts of novelty, and may betake themselves again to, and remain stationary within, the most secure harbour of their placid and good mother, and may begin by vomiting up those bitter and turbid floods of error which they had swallowed, that thenceforward they may be able to drink the streams of fresh and living water. Let them unlearn well what they had learnt not well, and let them receive so much of the entire doctrine of the Church as they can understand: what they cannot understand let them believe.
