You can say that again:)
While not necessarily being adverse to such things as affirming the people’s “acknowledging and adoring an overruling providence” (as in his First Inaugural Address, [3]) and expressing the need for “the favor of that Being in whose hands we are, who led our fathers, as Israel of old,”[4] in his second inauguration, yet together with James Madison, Jefferson carried on a long and successful campaign against state financial support of churches in Virginia. It is Jefferson who created the phrase “wall of separation between church and state” in his 1802 letter to the Danbury Baptists of Connecticut.
Following the Revolution, the Church of England in America was disestablished. It reorganized as the Episcopal Church in America. Margaret Bayard Smith, whose husband was a close friend of Jefferson, records that during the first winter of Jefferson’s Presidency he regularly attended service on Sunday in a small humble Episcopalian church out of respect for public worship. This was the only church in the new city, with the exception of a little Catholic chapel. Within a year of his inauguration, Jefferson began attending church services in the House of Representatives, a custom had not yet begun while he was Vice President, and which featured preachers of every Christian sect and denomination.[11] In January 1806 a female evangelist, Dorothy Ripley, delivered a camp meeting-style exhortation in the House to Jefferson, Vice President Aaron Burr, and a “crowded audience.” Throughout his administration Jefferson permitted church services in executive branch buildings, which were acceptable to Jefferson because they were nondiscriminatory and voluntary, and because he believed that religion was an important support for republican government.[12]
Henry S. Randall, the only biographer permitted to interview Jefferson’s immediate family, recorded that Jefferson “attended church with as much regularity as most of the members of the congregation - sometimes going alone on horse- back, when his family remained at home,” and that he also “contributed freely to the erection of Christian churches, gave money to Bible societies and other religious objects, and was a liberal and regular contributor to the support of the clergy. Letters of his are extant which show him urging, with respectful delicacy, the acceptance of extra and unsolicited contributions, on the pastor of his parish, on occasions of extra expense to the latter, such as the building of a house..”[13]
In later years, Jefferson refused to serve as a godparent for infants being baptized, because he did not believe in the dogma of the Trinity.[14] Despite testimony of Jefferson’s church attendance, there is no evidence that he was ever confirmed or was a communicant.[15]
