Scripture's perfection as to what it contains: divine revelation and catholic dogmas of the faith
II. But it also embraces what is necessary — both insofar as divine revelation is the principal cause of knowing, and insofar as the catholic dogmas of the faith, or revealed propositions, on which religion properly rests, and which have the force of an infallible principle for framing further conclusions, are signified.
It is worth noting here that all who agree in these principles understood in either way are also to be judged to agree in the foundation of religion, and cannot properly be held heretics or unbelievers as far as doctrine is concerned — by the argument of 1 Corinthians 3:15. But those who are ignorant of these principles, or deliberately dissent in them, are no more Christians than those who ignore or deny principles known by nature have commonly been sound.
III. Divine revelation we explained in Chapter 2. But a catholic dogma of the faith is elsewhere taken for a principle, elsewhere for any conclusion truly drawn from a principle — either manifestly and evidently, or not equally manifestly. In the former mode a dogma of the faith cannot be denied by any Christian; yet that can happen in the latter mode.
IV. Catholic dogmas, or the principles and foundations of the Christian religion, are called necessary either with respect to eternal salvation, or with respect to institution, or finally with respect to certainty.
Latin
II. Complectitur autem necessaria, tum quatenus revelationem divinam, ut principalem causam cognoscendi, tum quatenus dogmata fidei catholica seu propositiones revelatas, in quibus religio proprie fundatur, quaeque ad conclusiones alias conficiendas infallibilis principii vim habent, significant. Dignum hic notatu est, quod ii omnes, qui in principiis hoc utroque modo intellectis consentiunt, etiam in fundamento religionis consentire judicandi sint, nec pro haereticis aut infidelibus, quantum ad doctrinam attinet, proprie haberi possint, argumento 1. Cor. 3. vers. 15. qui vero haec principia ignorant, aut in iis ex proposito dissentiunt, non magis Christiani sint, quam qui principia natura nota ignorant, aut negant, sani esse consueverunt. III. Revelationem divinam C. 2. explicavimus: dogma autem fidei catholicum alias capitur pro principio, alias pro quavis conclusione ex principio vel manifeste ac evidenter, vel non aeque manifeste, vere tamen deducta. Priori modo dogma fidei a nullo Christiano negari potest: quod tamen posteriori modo accidere potest. IV. Dogmata catholica seu principia ac fundamenta religionis Christianae dicuntur necessaria vel respectu aeternae salutis, vel respectu institutionis, vel denique respectu certitudinis.
