"This is the common opinion of divines. Reason has need of divine grace, not only in gross, illiterate persons, but even in those of parts and learning; for how clear-sighted soever that may be, yet it cannot make us have Faith, if celestial light does not illuminate us within, because, as I have said already, divine Faith being of a superior order cannot derive its efficacy from human faith."[336:1] "This is likewise the doctrine of St. Thomas Aquinas: 'The light of Faith makes things seen that are believed.' He says moreover, 'Believers have knowledge of the things of Faith, not in a demonstrative way, but so as by the light of Faith it appears to them that they ought to be believed.'"[336:2] 10. It is evident what a special influence such doctrine as this must exert upon the theological method of those who hold it. Arguments will come to be considered as suggestions and guides rather than logical proofs; and developments as the slow, spontaneous, ethical growth, not the scientific and compulsory results, of existing opinions. § 3. _Theology._ I have spoken and have still to speak of the action of logic, implicit and explicit, as a safeguard, and thereby a note, of legitimate developments of doctrine: but I am regarding it here as that continuous tradition and habit in the Church of a scientific analysis of all revealed truth, which is an ecclesiastical principle rather than a note of any kind, as not merely bearing upon the process of development, but applying to all religious teaching equally, and which is almost unknown beyond the pale of Christendom. Reason, thus considered, is subservient to faith, as handling, examining, explaining, recording, cataloguing, defending, the truths which faith, not reason, has gained for us, as providing an intellectual expression of supernatural facts, eliciting what is implicit, comparing, measuring, connecting each with each, and forming one and all into a theological system. 2.
