Providence has given to our people the choice of their rulers, and it is the duty, as well as the privilege and interest of our Christian nation to select and prefer Christians for their rulers.” Source: October 12, 1816.

“Whether our religion permits Christians to vote for infidel rulers is a question which merits more consideration than it seems yet to have generally received either from the clergy or the laity. It appears to me that what the prophet said to Jehoshaphat about his attachment to Ahab ["Shouldest thou help the ungodly and love them that hate the Lord?" 2 Chronicles 19:2] affords a salutary lesson.” [The Correspondence and Public Papers of John Jay, 1794-1826, Henry P. Johnston, editor (New York: G.P. Putnam's Sons, 1893), Vol. IV, p.365]
Think about this, quite a bit different from what your teacher toldy you, eh?
