I found this excellent quote by John Newton. I would like you all to read it.

I repeat my advice to read the Scriptures with prayer, to keep close the important points, of human depravity, regeneration, the atonement, and the necessity of divine teaching. If a man is born again, hates sin, and depends upon the Savior for life and grace, I care not whether he be an Arminian or a Calvinist. If he be not born again, he is nothing, let him be called by what name he will.

Jonathan Aiken in his biography of John Newton was using this quote to show that he wrote letters to convey his most important messages. Aiken says that from this letter is was obvious that Newton was dismissive of denominational labels. I want to show it because it was Mr. Newton’s view of a Christian and I agree with it. I’m not sure what source it was from. I was struggling to understand how to use the Sources and Biographical Notes section of the Book.
The source I believe it was from is written in this way on page 390 of the Book: Campbell: July 18, 1795, pp. 75-76.
The quote itself is on page 340 of Jonathan Aiken’s Book, John Newton; Disgrace to Amazing Grace, Crossway Books, 2007.
