I wrote this in 2010. Here is the "quotation" from Livingston, I uncovered:
Hence the motley junction of king-craft and priest-craft (the most fatal engine ever invented by Satan for promoting human wretchedness) usually called the alliance between church and state, but in reality a most atrocious conspiracy between two public robbers, for sharing between them the plunder of nations; and for that purpose mutually supporting and supported by each other. And hence all politico-ecclesiastical establishments under pretence of promoting religion, by kings who generally have none, and church dignitaries who seldom care for any.
