If this is, on the whole, a true view of the general shape under which the existing body of developments, commonly called Catholic, present themselves before us, antecedently to our looking into the particular evidence on which they stand, I think we shall be at no loss to determine what both logical truth and duty prescribe to us as to our reception of them. It is very little to say that we should treat them as we are accustomed to treat other alleged facts and truths and the evidence for them, such as come to us with a fair presumption in their favour. Such are of every day's occurrence; and what is our behaviour towards them? We meet them, not with suspicion and criticism, but with a frank confidence. We do not in the first instance exercise our reason upon opinions which are received, but our faith. We do not begin with doubting; we take them on trust, and we put them on trial, and that, not of set purpose, but spontaneously. We prove them by using them, by applying them to the subject-matter, or the evidence, or the body of circumstances, to which they belong, as if they gave it its interpretation or its colour as a matter of course; and only when they fail, in the event, in illustrating phenomena or harmonizing facts, do we discover that we must reject the doctrines or the statements which we had in the first instance taken for granted. Again, we take the evidence for them, whatever it be, as a whole, as forming a combined proof; and we interpret what is obscure in separate portions by such portions as are clear. Moreover, we bear with these in proportion to the strength of the antecedent probability in their favour, we are patient with difficulties in their application, with apparent objections to them drawn from other matters of fact, deficiency in their comprehensiveness, or want of neatness in their working, provided their claims on our attention are considerable. 3.
