The first and most pressing application of the principles at issue described in the preceding section, must be concerned with that assent of the human mind which is claimed for the truths revealed. The Catholic Church has always been explicit in affirming that the truths of Christ were dogmas to be accepted by faith. She has consistently corrected those of her members who have ventured to maintain that these dogmas lay within reach of unaided reason. They are to be received by faith, and faith was to be defined as an assent of the mind, not based upon the intrinsic evidence of the truth accepted, but based upon the word of an authority revealing. It was said to Nicodemus: ‘I Say to thee that we speak what we know, and we testify what we nave seen, and you receive not our testimony. If I have spoken to you earthly things and you believe not, how will you believe, if I shall speak to you heavenly things?’ (John 3, 11-2).
