Supernatural per se and per accidens: Elijah's chariot and Samson's strength; the blind man's sight and Solomon's wisdom
To make their meaning clearer on this point, they note that something is called supernatural in two ways, in itself (per se) and by circumstance (per accidens).
What by its very kind is not fitted to flow from nature's principles is supernatural in itself, like Elijah's going up to heaven in a fiery chariot, Samson's strength, and other things of that sort. What is sometimes obtained by a divine miracle, though otherwise it usually flows from nature's principles, is supernatural by circumstance. Such was the sight the Lord gave back to the man born blind, the wisdom God gave Solomon, and many other things we read in Scripture.
Latin
VII. Ut autem hac in parte mentem suam clarius explicent, observant aliquid supernaturale dici duobus modis, per se & per accidens. Per se dicitur supernaturale, quod ex genere suo non est aptum fluere ex principiis naturae: qualis fuit ascensus Eliae igneo curru in coelum, robur Sampsonis, & alia id genus. Per accidens supernaturale vocatur quod interdum obtinetur divino miraculo, licet alioquin ex naturae principiis fluere soleat. Talis fuit sensus videndi quem Dominus caeco nato restituit: sapientia Salomoni divinitus tributa, & alia non pauca quae in scripturis leguntur.
