"You became a believer because you saw me. Blest are they who have not seen and have believed. Those words are a great consolation for us every time we say, every time we proclaim: O blessed eyes! O blessed times! O blessed ages, which deserved to witness and examine such great mysteries! This is true, for the Lord said: Blest are the eyes that see what you see, but he also said: Blest are they who have not seen and have believed. The first gave more consolation; the latter was more meritorious. Seeing increases gladness, but faith without seeing gives greater glorification."
Thomas of Villanova, O.S.A. (AD 1486 - 1555), Dominca in Albis 1-2: Opera Omnia II, 316
