_Lastly_, to address specially Lutherans and Anglicans. They are well aware that almost all sects are not more opposed to the supremacy of Peter than to the superiority of bishops, and the verity of the Lord's body in the Eucharist. But are they therefore deterred by the number of their enemies, or do they distrust the goodness of their cause, or doubt the perspicuity of those documents on which they rely for the victory? They can afford to disdain the tricks of their opponents, as well as repulse their attacks. They must, accordingly, agree with us that the assertions or denials of contesting parties ought not to be, and cannot be, the test of a cause's goodness, and of documentary evidence. But, then, by what standard are we to go? I reply, by those criteria which are not subject to just exception, and which must be approved by all who seek the truth, and obey the dictate of reason. Now four such criteria in chief I think may be assigned, the two former of which are _immediate_ and _internal_, the third _internal_, but somewhat more remote; the fourth, _external_, but of great weight, and not to be overlooked. To speak of the former first; one of these is _verbal_, and belongs to the words and phrases of which the text consists; the other _real_, and regards the meaning of the sentence. Indeed, no other sources of obscurity or of clearness can be imagined than either the _words_ which express the _matter_, or the _matter_ intended by the _words_. If both words and matter are plain, and perspicuous, the discourse will be clear, and the language distinct; but if either the matter exceed the power of reason, or the words do not run clear, or both these conspire, the evidence of the meaning will be more or less impaired.
