Such being the plain teaching of the Fathers, and such the duty of following it, Vincentius proceeds to speak of the misery of doubting and change:—
"Which being so, he is a true and genuine Catholic that loveth the truth of God, the Church, the body of Christ; that preferreth nothing before the religion of God; nothing before the Catholic faith; not any man's authority, not love, not wit, not eloquence, not philosophy; but contemning all these things, and in faith abiding fixed and stable, whatsoever he knoweth the Catholic Church universally in old times to have holden, that only he purposeth with himself to hold and believe; but whatsoever doctrine, new and not before heard of, such an one shall perceive to be afterwards brought in of some one man, beside all or contrary to all the saints, let him know that doctrine doth not pertain to religion, but rather to temptation, especially being instructed with the sayings of the blessed Apostle St. Paul. For this is that which he writeth in his first Epistle to the Corinthians: 'There must (quoth he) be heresies also, that they which are approved may be made manifest among you.' ...
"O the miserable state of [waverers]! with what seas of cares, with what storms, are they tossed! for now at one time, as the wind driveth them, they are carried away headlong in error; at another time, coming again to themselves, they are beaten back like contrary waves; sometime with rash presumption they allow such things as seem uncertain, at another time of pusillanimity they are in fear even about those things which are certain; doubtful which way to take, which way to return, what to desire, what to avoid, what to hold, what to let go; which misery and affliction of a wavering and unsettled heart, were they wise, is as a medicine of God's mercy towards them.
"Which being so, oftentimes calling to mind and remembering the selfsame thing, I cannot sufficiently marvel at the great madness of some men, at so great impiety of their blinded hearts, lastly, at so great a licentious desire of error, that they be not content with the rule of faith once delivered us, and received from our ancestors, but do every day search and seek for new doctrine, ever desirous to add to, to change, and to take away something from, religion; as though that were not the doctrine of God, which it is enough to have once revealed, but rather man's institution, which cannot but by continual amendment (or rather correction) be perfected."—Ch. 25, 26.
