John Adams' list of those most responsible for American Independence: Samuel Cooper, Jonathan Mayhew, Charles Chauncy, and George Whitefield. He calls them all ministers of the gospel and all Christians. In reality ONLY WHITEFIELD was a "Christian" as evangelicals define and understand the term. The others, including J. Adams were Trinity deniers..But America's key Founders and the notable patriotic preachers they followed (Revs. Mayhew, Chauncy, Cooper and others) disbelieved in central Christian tenets like original sin, trinity, incarnation, and atonement, such that they are disqualified as "Christians" in the eyes of large sectors of believers in historic traditional Christianity.However, as I have discovered, Cooper was an evangelical, who believed in Original Sin, the Vicarious Blood Atonement, eternal judgment, and justification by grace:
[A]nd at last redeemed the Church by his own Blood..Love, by the Example of the compassionate Redeemer, who takes “the Lambs in his Arms; ”and who when He dwelt among us in Flesh..The knowledge we are to dispense to others is chiefly to be drawn from the Holy Spriptures; and by conversing with them, we become acquainted with the pecular doctrines of Christianity: such as the apostacy of human nature; the guilt and condemnation into which all men have fallen; the person and offices of the Redeemer; our pardon and justification through his obedience and sacrifice; the conditions of the covenant of grace; the nature and extent of that holiness without which no man shall see the Lord; and the necessity of the influences of the Holy Spirit to form us to it...Your Discourses will be evangelical and instructive, warm and persuasive.
