Some revealed things are known only supernaturally; Scripture also presupposes truths known by nature
VIII. That object is the things revealed — either had purely and uniquely from supernatural revelation, or also knowable from elsewhere.
Those called revealed κατ' ἐξοχήν, preeminently, stand apart from other dogmas Scripture contains that the light of nature also knows (Romans 1:19–Romans 1:21; Romans 2:14–Romans 2:15; Acts 14:17; Hebrews 11:6). So Theophylact on Hebrews 11: That God is, he says, we hold by faith. Others, following Thomas (Summa I q.2 a.2 ad 1), call that other truth a presupposition of faith and a preamble to the articles of faith.
Scripture presupposes this and the other dogmas of this clause — and the weight of such matters — as known from elsewhere and also to be drawn from nature's light. So they wrong the truth who claim that nature's light conflicts with Scripture, or who think anyone can explain Scripture rightly and sufficiently without secular learning. Otherwise even the unlearned, once they had read and reread the Scriptures, would be great theologians — as certain Anabaptists believe.
The Apostle of the Gentiles himself condemns such men when he expressly appeals to what nature teaches (1 Corinthians 11:14): ἢ οὐδὲ αὐτὴ ἡ φύσις διδάσκει ὑμᾶς; — Does not nature itself teach you this?
Latin
VIII. Illud sunt res revelatae, quae vel pure & unice ex revelatione supernaturali habentur, vel etiam aliunde sciri possunt. Illa κατ' ἐξοχήν revelata dicuntur, praeter quae alia dogmata scriptura continet, ex lumine naturae quoque nota, ut Rom. 1. 19. 20. 21. & 2. 14. 15. Act. 14. 17. Hebr. 11. 6. Hinc Theophylactus in Heb. 11. Deum esse, ait, per fidem tenemus: alii vero aliud ex Thomae part. 1. q. 2. art. 2. resp. ad 1. vocant praesuppositum fidei & praeambulum ad fidei articulos. Hoc & hujus commatis alia dogmata rerumque momenta scriptura supponit tanquam aliunde nota & e lumine naturae quoque petenda, ut iniquiores sint veritati, qui lumen naturae repugnare scripturae statuunt, aut eam recte & sufficienter a quovis absque literatura seculari explicari posse censent: alioquin etiam idiotae, ubi scripturas legerint atque relegerint, magni Theologi fuerint, ut quidam Anabaptistae credunt. Quin ipse gentium Apostolus hos tales damnat, cum disertim ad ea, quae natura docet, provocat 1 Cor. 11. 14. ἢ οὐδὲ αὐτὴ ἡ φύσις διδάσκει ὑμᾶς; Anne natura quidem ipsa hoc vos docet?
