I have written at considerable length: yet so vast is the subject, that I may seem to some to have written superficially, and to have left my statements without adequate support. I can only say that no one paragraph has been written hastily, nor in fact is there one the substance of which has not been for several years in my mind; indeed, in many instances, not only the substance, but the proofs in detail have been actually written: but to have inserted them here would have been impracticable, as they would have been in themselves a volume. Neither have I knowingly remained in ignorance of any argument which may have been used in defence of Mr. Newman's system; I have always desired to know what he and his friends say, and on what grounds they say it; although, as I have not read the Tracts for the Times regularly, I may have omitted something which it would have been important to notice. Finally, in naming Mr. Newman as the chief author of the system which I have been considering, I have in no degree wished to make the question personal; but Mr. Percival's letter authorizes us to consider him as one of the authors of it; and as I have never had any personal acquaintance with him, I could mention his name with no shock to any private feelings either in him or in myself. But I have spoken of him simply as the maintainer of certain doctrines, not as maintaining them in any particular manner, far less as actuated by any particular motives. I believe him to be in most serious error; I believe his system to be so destructive of Christ's church, that I earnestly pray, and would labour to the utmost of my endeavours for its utter overthrow: but on the other hand, I will not be tempted to confound the authors of the system with the system itself; for I know that the most mischievous errors have been promulgated by men who yet have been neither foolish nor wicked; and I nothing doubt that there are many points in Mr. Newman, in which I might learn truth from his teaching, and should be glad if I could come near him in his practice.
