[This treatise was written while our author was a Catholic. This seems to me the best supported of the theories concerning it. Let us accept Pamelius, for once and date it a.d. 198. Dr. Allix following Baronius, will have it as late as a.d. 208. Neander thinks the work, after the quotation from Isaiah in the beginning of chapter ninth, is not our author's, but was finished by another hand, clumsily annexing what is said on the same chapter of Isaiah in the Third Book against Marcion. It is only slightly varied. Bp. Kaye admits the very striking facts instanced by Neander, in support of this theory, but demolishes, with a word any argument drawn from thence that the genuine work was written after the author's lapse. This treatise is sufficiently annotated by Thelwall, and covers ground elsewhere gone over in this Series. My own notes are therefore very few.] ↩
