This stinging 'letter' to the printer of the Public Advertiser newspaper was published by John Wesley in 1780. In it, he takes issue with a recently-published government act of tolerance - implied or real - of Roman Catholicism.
The letter is very interesting. Clearly, it was an article in the form of a letter intended for publication in the Public Advertiser paper. However, it is worded in such a way as to avoid censorship (the government act is only referred to in passing, for example). The letter leaves no doubt whatsoever as to Wesley's negative view of the Roman Catholic Church.
