A taste from Sparks:
And Locke must still be considered a Unitarian, till he can be proved a Trinitarian ; a task, which it is not likely you will soon undertake. At all events, he had no faith in the assemblage of articles, which you denominate the essence of christianity, and without believing which, you say, no one can be called a Christian. His whole treatise on the Reasonableness of Christianity bears witness to this truth. For the leading object of that work is to show, that “the Gospel was written to induce men into a belief of this proposition, ‘that Jesus of Nazareth was the Messiah,’ which if they believed, they should have life.”* He says nothing about total depravity, the atonement, the “sanctifying spirit of an Almighty Surety,” nor any of your peculiar doctrines. Yet who has done more to elucidate the sacred Scriptures, or to prove the consistency and reasonableness of the religion of Jesus? Your rule, however, will take from him the Christian name.
