"Since 95% of founders were religious they were one and the same."
This misses the point. Just because one is "religious" does not necessarily mean they are Christians.
The country was founded on Christianity? Most founders would probably acknowledge some type of religious influence, but not necessarily Christianity me thinks.

Adams signed the Treaty of Tripoli (June 7, 1797). Article 11 states:
“The government of the United States is not in any sense founded on the Christian religion.”
From Jefferson’s biography:
“...an amendment was proposed by inserting the words, ‘Jesus Christ...the holy author of our religion,’ which was rejected ‘By a great majority in proof that they meant to comprehend, within the mantle of its protection, the Jew and the Gentile, the Christian and the Mohammedan, the Hindoo and the Infidel of every denomination.’”
