An Argument Against Abolishing Christianity begins with following:
I am very sensible what a weakness and presumption it is to reason against the general humour and disposition of the world. I remember it was with great justice, and a due regard to the freedom, both of the public and the press, forbidden upon several penalties to write, or discourse, or lay wagers against the — even before it was confirmed by Parliament; because that was looked upon as a design to oppose the current of the people, which, besides the folly of it, is a manifest breach of the fundamental law, that makes this majority of opinions the voice of God. In like manner, and for the very same reasons, it may perhaps be neither safe nor prudent to argue against the abolishing of Christianity, at a juncture when all parties seem so unanimously determined upon the point, as we cannot but allow from their actions, their discourses, and their writings.
What historical event does Swift allude to in this paragraph? What written opinions were forbidden?
