In the autumn of 1845 Mr. Sawyer removed with his family to Clinton, Oneida Co., N. Y., and took charge of the Clinton Liberal Institute. He succeeded in converting it into a Universalist school, and opened in connection with it a primitive theological school from which he sent out about twenty-five students, more than twenty of whom are still in the ministry well and successfully employed. At the close of 1852 he returned to New York, and, having preached for what was formerly called the Dry Dock Society a year, he returned to his old parish and continued with it until the spring of 1861, when, on the breaking out of the Rebellion, and the volunteering of his oldest son on his farm at Clinton, and on account of parish affairs in that distracted time, he resigned and went to Clinton, where he remained, preaching for the parish there until January, 1863, when he again returned to New York, and took the editorial charge of the "Christian Ambassador." This paper was founded by Philo Price in 1831, under the name of "The Christian Messenger," of which Mr. Sawyer was the theological editor for several years. It passed under several names, and is now published at Boston as the "Christian Leader," united with the Universalist weekly formerly issued in this city. In the autumn of 1865 he removed his family from Clinton to Star Landing, N. J., and took possession of a farm he had just purchased there. Here he remained, managing the farm and preaching occasionally, until the autumn of 1869, when he came to College Hill, Mass., and assumed the duties of Professor of Systematic Theology in the Divinity School, to which he had some time before been elected. He was one of the original trustees of Tufts College, having called the educational convention held in New York in 1847, which resulted in the establishment of the college. He was also chiefly instrumental in calling the first meeting in New York city to consider the necessity of establishing a theological school, which resulted in the founding of the Canton Theological School and the St. Lawrence University, of which he was also one of the original trustees, and for several years President of the Board. He received the honorary degree of S. T. D. at Cambridge, in 1850.
