Nor is there surely any thing derogatory to the position of a Catholic in such a proceeding. The Church has ever appealed and deferred to witnesses and authorities external to herself, in those matters in which she thought they had means of forming a judgment: and that on the principle, _Cuique in arte sua credendum_. She has even used unbelievers and pagans in evidence of her truth, as far as their testimony went. She avails herself of scholars, critics, and antiquarians, who are not of her communion. She has worded her theological teaching in the phraseology of Aristotle; Aquila, Symmachus, Theodotion, Origen, Eusebius, and Apollinaris, all more or less heterodox, have supplied materials for primitive exegetics. St. Cyprian called Tertullian his master; St. Augustin refers to Ticonius; Bossuet, in modern times, complimented the labours of the Anglican Bull; the Benedictine editors of the Fathers are familiar with the labours of Fell, Ussher, Pearson, and Beveridge. Pope Benedict XIV. cites according to the occasion the works of Protestants without reserve, and the late French collection of Christian Apologists contains the writings of Locke, Burnet, Tillotson, and Paley. If, then, I come forward in any degree as borrowing the views of certain Protestant schools on the point which is to be discussed, I do so, Gentlemen, as believing, first, that the Catholic Church has ever, in the plenitude of her divine illumination, made use of whatever truth or wisdom she has found in their teaching or their measures; and next, that in particular places or times her children are likely to profit from external suggestions or lessons, which have not been provided for them by herself.
And here I may mention a third reason for appealing at the outset to the proceedings of Protestant bodies in regard to Liberal Education. It will serve to intimate the mode in which I propose to handle my subject altogether. Observe then, Gentlemen, I have no intention, in any thing I shall say, of bringing into the argument the authority of the Church, or any authority at all; but I shall consider the question simply on the grounds of human reason and human wisdom. I am investigating in the abstract, and am determining what is in itself right and true. For the moment I know nothing, so to say, of history. I take things as I find them; I have no concern with the past; I find myself here; I set myself to the duties I find here; I set myself to further, by every means in my power, doctrines and views, true in themselves, recognized by Catholics as such, familiar to my own mind; and to do this quite apart from the consideration of questions which have been determined without me and before me. I am here the advocate and the minister of a certain great principle; yet not merely advocate and minister, else had I not been here at all. It has been my previous keen sense and hearty reception of that principle, that has been at once the reason, as I must suppose, of my being selected for this office, and is the cause of my accepting it. I am told on authority that a principle is expedient, which I have ever felt to be true. And I argue in its behalf on its own merits, the authority, which brings me here, being my opportunity for arguing, but not the ground of my argument itself.
