In papers this morning (Newark Star-Ledger, 7/5, page A7), entitled "In God We Trust". The link is www.hobbylobby.com.ministryprojects, but I can't find the ad.
Pro-Christian quotes from Founding Fathers, Presidents, Supreme Court Justices and Rulings, Congress, education and foreign opinion.
Founding Fathers: Patrick Henry (known conservative at the time, part of the opposition to the constitution); Jedediah Morse (who?), Benjamin Franklin (pretty clearly ceremonial Christianity--I suspect recommending a chaplain to the Constitutional Convention).
Presidents: Washington (ceremonial), Adams (pro-religion, not pro-Christian), Madison (ditto), Jefferson (ditto), JQ Adams (I'll give them this one).
SCOTUS Justices: Jay, Wilson, Story (all very early).
SCOTUS Rulings: Both from the 19th century. Church of the Holy Trinity (pretty clearly saying acknowledging the common belief, not its validity), Vidal vs. Girard's executors (encouraging public school Bible reading as moral development, 1844).
Congress: Judiciary Committee reports, 1853 & 1854. Both fair cops, as far as that goes.
Education: Harvard (1636) and Yale (1787) student guidelines. The first very strong, but given that Harvard both private and primarily a seminary at the time, not surprising.
Foreign opinion: de Toqueville (1831) and Murat (1832), both remarking on the fact of American religiosity, not on its merits.
So, only one quote from after the Civil War, and that probably an obiter dictum in the Church of the Holy Trinity case. And only four other non-ceremonial, strongly pro-Christian or pro-Bible--Patrick Henry, JQ Adams, and the two college student handbooks.
