The Trinity, as Bishop Leighton has well remarked, is "a doctrine of faith, not of demonstration," except in a _moral_ sense. If the New Testament declare it, not in an insulated passage, but through the whole breadth of its pages, rendering, with any other admission, the book which is the Christian's anchor-hold of hope, dark and contradictory, then it is not to be rejected, but on a penalty that reduces to an atom, all the sufferings this earth can inflict. Let the grand question be determined.--Is, or is not the Bible _inspired_? No one book has ever been subjected to so rigid an investigation as the Bible, by minds the most capacious, and in the result, which has so triumphantly repelled all the assaults of infidels. In the extensive intercourse which I have had with this class of men, I have seen their prejudices surpassed only by their ignorance. This I found particularly the case in Dr. Darwin (Letter 19), the prince of their fraternity. Without therefore, stopping to contend on what all dispassionate men must deem, undebatable ground, I may assume inspiration as admitted; and, equally so, that it would be an insult to man's understanding, to suppose any other Revelation from God than the Christian Scriptures. If these Scriptures, impregnable in their strength, sustained in their pretensions, by undeniable prophecies and miracles, and by the experience of the _inner man_, in all ages, as well as by a concatenation of arguments, all bearing upon one point, and extending with miraculous consistency, through a series of fifteen hundred years; if all this combined proof does not establish their validity, nothing can be proved under the sun; but the world and man must be abandoned, with all its consequences, to one universal scepticism! Under such sanctions, therefore, if these Scriptures, as a fundamental truth, _do_ inculcate the doctrine of the _Trinity_; however surpassing human comprehension; then I say, we are bound to admit it on the strength of _moral demonstration_. The supreme Governor of the world and the Father of our spirits, has seen fit to disclose to us much of his will, and the whole of his natural and moral perfections. In some instances he has given his _word_ only, and demanded our _faith_; while on other momentous subjects, instead of bestowing full revelation, like the _Via Lactea_, he has furnished a glimpse only, through either the medium of inspiration, or by the exercise of those rational faculties with which he has endowed us. I consider the Trinity as substantially resting on the first proposition, yet deriving support from the last.
