"Holy Scripture," says Cornelius à Lapide, "contains the beginnings of all theology: for theology is nothing but the science of conclusions which are drawn from principles certain to faith, and therefore is of all sciences most august as well as certain; but the principles of faith and faith itself doth Scripture contain; whence it evidently follows that Holy Scripture lays down those principles of theology by which the theologian begets of the mind's reasoning his demonstrations. He, then, who thinks he can tear away Scholastic Science from the work of commenting on Holy Scripture is hoping for offspring without a mother."[342:1] Again: "What is the subject-matter of Scripture? Must I say it in a word? Its aim is _de omni scibili_; it embraces in its bosom all studies, all that can be known: and thus it is a certain university of sciences containing all sciences either 'formally' or 'eminently.'"[342:2] Nor am I aware that later Post-tridentine writers deny that the whole Catholic faith may be proved from Scripture, though they would certainly maintain that it is not to be found on the surface of it, nor in such sense that it may be gained from Scripture without the aid of Tradition. 5. 2. And this has been the doctrine of all ages of the Church, as is shown by the disinclination of her teachers to confine themselves to the mere literal interpretation of Scripture. Her most subtle and powerful method of proof, whether in ancient or modern times, is the mystical sense, which is so frequently used in doctrinal controversy as on many occasions to supersede any other. Thus the Council of Trent appeals to the peace-offering spoken of in Malachi in proof of the Eucharistic Sacrifice; to the water and blood issuing from our Lord's side, and to the mention of "waters" in the Apocalypse, in admonishing on the subject of the mixture of water with the wine in the Oblation. Thus Bellarmine defends Monastic celibacy by our Lord's words in Matthew xix., and refers to "We went through fire and water," &c., in the Psalm, as an argument for Purgatory; and these, as is plain, are but specimens of a rule. Now, on turning to primitive controversy, we find this method of interpretation to be the very basis of the proof of the Catholic doctrine of the Holy Trinity. Whether we betake ourselves to the Ante-nicene writers or the Nicene, certain texts will meet us, which do not obviously refer to that doctrine, yet are put forward as palmary proofs of it. Such are, in respect of our Lord's divinity, "My heart is inditing of a good matter," or "has burst forth with a good Word;" "The Lord made" or "possessed Me in the beginning of His ways;" "I was with Him, in whom He delighted;" "In Thy Light shall we see Light;" "Who shall declare His generation?" "She is the Breath of the Power of God;" and "His Eternal Power and Godhead."
