John Quincy Adams (1767-1848) was the son of John Adams (our 2nd President) and our 6th President. He was a devout Christian. Here is a quote from him as he was in London and negotiating the Treaty of Ghent on December 24, 1814.
"I find in the New Testament, Jesus Christ accosted in His own presence by one of His disciples as God, without disclaiming the appellation. I see Him explicitly declared by at least two other of the Apostles to be God, expressly and repeatedly announced, not only as having existed before the worlds, but as the Creator of the worlds without beginning of days or end of years. I see Him named in the great prophecy of Isaiah concerning him to be the mighty God! . . .
The texts are too numerous, they are from parts of the Scriptures too diversified, they are sometimes connected by too strong a chain of argument, and the inferences from them are, to my mind, too direct and irresistible, to admit of the explanations which the Unitarians sometimes attempt to give them, or the evasions by which, at others, they endeavor to escape from them."
