Scripture will ultimately suffice for a saving knowledge of God only when its certainty is founded upon the inward persuasion of the Holy Spirit. Indeed, these human testimonies which exist to confirm it will not be vain if, as secondary aids to our feebleness, they follow that chief and highest testimony. But those who wish to prove to unbelievers that Scripture is the Word of God are acting foolishly, for only by faith can this be known.
John CalvinThe church is the gathering of God's children, where they can be helped and fed like babies and then guided by her motherly care, grow up to manhood in maturity of faith.
John CalvinWithout Christ, sciences in every department are vain....The man who knows not God is vain, though he should be conversant with every branch of learning. Nay more, we may affirm this too with truth, that these choice gifts of God -- expertness of mind, acuteness of judgment, liberal sciences, and acquaintance with languages, are in a manner profaned in every instance in which they fall to the lot of wicked men.
