42. Præmittendum 4º, quod in Sacra Scriptura, et Ecclesiasticis traditionibus non traditur nisi id, quod ad animæ salutem necessarium est, quoad credendum, sperandum et amandum; unde inferre non licet ex eo, quod nec ex Scriptura, nec ex traditione aliquod habetur, proinde negandum sit, quod illud tale existat: aut nos quidem Fides docet, Deum per Verbum suum omnia creasse visibilia, et invisibilia; pariterque ex Jesu Christi Domini nostri meritis tum gratiam, tum gloriam omni, et cuivis rationali creaturæ conferri. Num autem alius Mundus a nostro, quem incolimus, sit, et in eo alii homines non ab Adam prognati, sed alio modo a Deo creati existant (sicut ponunt illi qui lunarem globum habitatum opinantur); pariterque num in hoc Mundo, quem incolimus, aliæ existant creaturæ rationales ultra homines, et Spiritus Angelicos, quæ regulariter hominibus sint invisibiles, et per accidens, et earum executiva potentia fiant visibiles: hoc nullo modo spectat ad fidem, et hoc scire, aut ignorare non est ad salutem hominis necessarium, sicut nec scire rerum omnium physicarum numerum aut naturam. 42. Fourthly, I premise that Holy Scripture and ecclesiastical tradition do not teach us any thing beyond what is requisite for the salvation of the soul, namely Faith, Hope and Charity. Consequently, from a thing not being stated either by Scripture or tradition it must not be inferred that that thing is not in existence. For instance, Faith teaches us that God, by His Word, made things visible, and invisible, and also that, through the merits of our Lord Jesus-Christ, grace and glory are conferred on every rational creature. Now, that there be another World than the one we live in, and that it be peopled by men not born of Adam but made by God, in some other way, as is implied by those who believe the lunar globe to be inhabited; or further, that in the very World we dwell in, there be other rational creatures besides man and the Angelic Spirits, creatures generally invisible to us and whose being is disclosed but accidentally, through the instrumentality of their own power; all that has nothing to do with Faith, and the knowledge or ignorance thereof is no more necessary to the salvation of man than knowing the number or nature of all physical things.
