We have now, it Seems a National Bible Society, to propagate King James's Bible, through all Nations. Would it not be better to apply these pious Subscriptions, to purify Christendom from the Corruptions of Christianity; than to propagate those Corruptions in Europe Asia, Africa and America! … Conclude not from all this, that I have renounced the Christian religion, or that I agree with Dupuis in all his Sentiments. Far from it. I see in every Page, Something to recommend Christianity in its Purity and Something to discredit its Corruptions. … The Ten Commandments and the Sermon on the Mount contain my Religion.
