Theodotus and his followers fastened on the first part of St. John viii. 40, when they pretended to shew from Scripture that Christ is mere Man[505]. I am persuaded that the reading 'of My Father[506],'--with which Origen[507], Epiphanius[508], Athanasius[509], Chrysostom[510], Cyril Alex.[511], and Theodoret[512] prove to have been acquainted,--was substituted by some of the orthodox in this place, with the pious intention of providing a remedy for the heretical teaching of their opponents. At the present day only six cursive copies are known to retain this trace of a corruption of Scripture which must date from the second century. We now reach a most remarkable instance. It will be remembered that St. John in his grand preface does not rise to the full height of his sublime argument until he reaches the eighteenth verse. He had said (ver. 14) that 'the Word was made flesh,' &c.; a statement which Valentinus was willing to admit. But, as we have seen, the heresiarch and his followers denied that 'the Word' is also 'the Son' of God. As if in order to bar the door against this pretence, St. John announces (ver. 18) that 'the only begotten Son, which is in the bosom of the Father, he hath declared him': thus establishing the identity of the Word and the Only begotten Son. What else could the Valentinians do with so plain a statement, but seek to deprave it? Accordingly, the very first time St. John i. 18 is quoted by any of the ancients, it is accompanied by the statement that the Valentinians in order to prove that the 'only begotten' is 'the Beginning,' and is 'God,' appeal to the words,--'the only begotten God who is in the bosom of the Father[513],' &c. Inasmuch, said they, as the Father willed to become known to the worlds, the Spirit of Gnosis produced the 'only begotten' 'Gnosis,' and therefore gave birth to 'Gnosis,' that is to 'the Son': in order that by 'the Son' 'the Father' might be made known. While then that 'only begotten Son' abode 'in the bosom of the Father,' He caused that here upon earth should be seen, alluding to ver. 14, one 'as the only begotten Son.' In which, by the way, the reader is requested to note that the author of the Excerpta Theodoti (a production of the second century) reads St. John i. 18 as we do.
