"I had got but a little way in my work, when my trouble returned upon me. The ghost had come a second time. In the Arian History I found the very same phenomenon, in a far bolder shape, which I had found in the Monophysite. I had not observed it in 1832. Wonderful that this should come upon me! I had not sought it out; I was reading and writing in my own line of study, far from the controversies of the day, on what is called a 'metaphysical' subject; but I saw clearly, that in the history of Arianism, the pure Arians were the Protestants, the semi-Arians were the Anglicans, and that Rome now was what it was then. The truth lay, not with the Via Media, but with what was called 'the extreme party.' As I am not writing a work of controversy, I need not enlarge upon the argument; I have said something on the subject in a volume, from which I have already quoted."
