Both senses: Scripture holds all faith-and-salvation necessaries — nothing outside binds
When our Churches say Scripture has everything necessary to faith and salvation, they mean necessary in both senses — not the first alone.
We do not only claim that nothing outside Scripture is such that without explicit faith and knowledge of it no one can be saved. We also claim that no one should be judged to sin against Christian faith and his own salvation merely for rejecting and attacking what sacred Scripture does not teach.
So our case is not proved by listing only what explicit faith for salvation needs. Faith’s scope is wider than that minimum — yet we still hold that nothing belongs to faith that Scripture does not contain.
Latin
V. Quum autem statuunt Ecclesiae nostrae ea, quae sunt ad fidem & salutem necessaria, in Scripturis omnia haberi, intelligunt necessaria non tantum primo modo, sed etiam secundo modo. Nec enim id solum volumus, extra Scripturam nihil esse sine cujus explicita fide & notitia ad salutem nemo pervenire possit: sed hoc quoque, neminem existimari debere in fidem Christianam, & salutem propriam peccare, eo quod rejiciat & impugnet aliquid quod Scriptura sacra non docet. Unde sequitur nostram sententiam non satis probari, inductione facta eorum quorum fides & cognitio explicita possit alicui ad salutem sufficere. Nam fides in genere ambitu suo plura comprehendit, quam ea quorum cognitio ad salutem necessaria sit. Ad fidem autem nihil pertinere censemus quod in Scriptura non reperiatur.
