From the book:
> Here I desire to impress upon the minds of my clerical brethren the important fact, that the gospel histories of Christ were written by men who had formerly been Jews (see Acts xxi. 20), and probably possessing the strong proclivity to imitate and borrow which their bible shows was characteristic of that nation ; and being written many years after Christ’s death, according to that standard Christian author, Dr. Lardner, it was impossible, under such circumstances, for them to separate (if they had desired to) the real facts and events of his life from the innumerable fictions and fables then afloat everywhere relative to the heathen Gods who had pre-enacted a similar history. Two reasons are thus furnished for their constructing a history of Christ almost identical with that of other Gods, as shown in chapters XXX., XXXI. and XXXII. of this work.
We really have no one’s word, but the word of his followers, and that is problematic. At least for non-Christians.
