In March, 1792, a Unitarian congregation was formed in Portland under the leadership of Thomas Oxnard, who had been an Episcopalian. Having been supplied with the works of Priestley and Lindsey through the generosity of Dr. Freeman, he became a Unitarian; and his personal intercourse with Dr. Freeman gave strength to his changed convictions. A number of persons of property and respectability of character joined him in accepting his new faith. In writing to his friend in November, 1788, Mr. Oxnard said: "I cannot express to you the avidity with which these Unitarian publications are sought after. Our friends here are clearly convinced that the Unitarian doctrine will soon become the prevailing opinion in this country. Three years ago I did not know a single Unitarian in this part of the country besides myself; and now, entirely from the various publications you have furnished, a decent society might be collected in this and the neighboring towns."[53] In 1792 an attempt was made to introduce a revised liturgy into the Episcopal church of Portland; and, when this was resisted, a majority of the congregation seceded and formed a Unitarian society, with Mr. Oxnard as the minister. This society was continued for a few years, and then ceased to exist. The members joined the first Congregational church, which in 1809, became Unitarian.[54] Also in 1792 was organized a Unitarian congregation in Saco, under the auspices of Hon. Samuel Thatcher, a member of Congress and a Massachusetts judge.[55] Mr. Thatcher had been an unbeliever, but through the reading of Priestley's works he became a sincere and rational Christian. He met with much opposition from his neighbors, and an effort was made to prevent his re-election to Congress; but it did not succeed. The Saco congregation was at first connected with that at Portland, and it seems to have ceased its existence at the same time.[56]
