I would suggest you read Dreisbach if you are going to insist on using Jefferson as an argument against the voluntary recitation of the words "under God" in the public square.
The Court distorts existing precedent to conclude that the school districts student-message program is invalid on its face under the Establishment Clause. But even more disturbing than its holding is the tone of the Courts opinion; it bristles with hostility to all things religious in public life. Neither the holding nor the tone of the opinion is faithful to the meaning of the Establishment Clause, when it is recalled that George Washington himself, at the request of the very Congress which passed the Bill of Rights, proclaimed a day of public thanksgiving and prayer, to be observed by acknowledging with grateful hearts the many and signal favors of Almighty God.
I find myself in agreement with Rehnquist, Scalia and Thomas.
