"All the Vulgarity of a Methodist Teacher" or sheer brilliance?

Not everyone in Fuller’s day regarded Andrew Fuller with a favourable eye. There were, of course, theological opponents like John Martin of London. And then there were writers like David Rivers who, in his Literary Memoirs of Living Authors of Great Britain (London: R. Faulder, 1798), I, 201-202, described Fuller as “the author of several Religious Tracts written with all the Vulgarity of a Methodist Teacher. He has written a controversial pamphlet against Socinianism, which displays a very small share, if any, of education or talent.” This blogger begs to differ and sees many of Fuller’s works as sheer brilliance.
