He who believeth then the divine Scriptures with sure judgment, receives in the voice of God, who bestowed the Scripture, a demonstration that cannot be impugned. Faith, then, is not established by demonstration. “Blessed therefore those who, not having seen, yet have believed (John 20:29) …..
For knowledge is a state of mind that results from demonstration; but faith is a grace which from what is indemonstrable conducts to what is universal and simple, what is neither with matter, nor matter, nor under matter.
(Clement of Alexandria: Stromateis, 2, 28, 4. ANF Volume 2)
