So a founding father mentioned Jesus Christ. So what? Doesn't mean that he wanted to shove his religious doctrines down everyone else's throats.
And he wasn't "THE" founding father. There was no ONE founding father.
And a quick note on the religious[ beliefs of the founding fathers
http://en.wikipedia.org/wiki/Founding_Fathers_of_the_United_States
Some of the 1787 delegates had no affiliation. The others were Protestants except for three Roman Catholics: C. Carroll, D. Carroll, and Fitzsimons. Among the Protestants Constitutional Convention delegates, 28 were Episcopalian, 8 were Presbyterians, 7 were Congregationalists, 2 were Lutherans, 2 were Dutch Reformed, and 2 were Methodists. Many of the more prominent Founding Fathers were vocal about their opposition to organized religion or anti-clerical, such as Jefferson. Some of them often related their anti-organized church leanings in their speeches and correspondence, including George Washington, John Adams, Thomas Jefferson (who created the "Jefferson Bible"), Benjamin Franklin, and Thomas Paine. However, a few of the more notable founders, such as Patrick Henry, were strong proponents of traditional religion. Several of the Founding Fathers considered themselves to be deists or held beliefs very similar to that of traditional Deists, including Franklin, Jefferson, Paine and Ethan Allen.[12]
So quite the mix there, yet you want to claim your version as the all American version?
