Under the leadership of the National Conference the Unitarian body underwent material changes in its internal organization and in its relations to other denominations. Not only did it bring the churches to act together in the local conferences and in its own sessions, but it taught then to co-operate for the protection of their pulpits against adventurers and immoral men. Before it was organized, the excessive spirit of independency in the churches would permit of no exercise of control as to their selection of ministers to fill their pulpits. At the fourth session of the National Conference, held in New York in October, 1870, the council, through Dr. Bellows, suggested that the local conferences refuse to acknowledge as ministers men of proven vices and immoralities. To carry out the spirit of this suggestion, Dr. Hale presented a resolution, which was adopted, asking the local conferences to appoint committees of fellowship to examine and to act upon candidates for the ministry. In October, 1870, the New York and Hudson River Conference created such a committee "to examine the testimonials of such as desire to become members of the conference and enter the Unitarian ministry." The seventh session of the National Conference, held at Saratoga in 1876, provided for the appointment of a committee of fellowship, and the list of names of those appointed to its membership appears in the printed report; but there is no record that the committee ever organized. In 1878 the council reported at considerable length on the desirableness of establishing such a committee; and, again, a committee of fellowship was appointed "to take into immediate consideration the subject of the introduction into the Unitarian ministry of those persons who seek an entrance into that ministry from other churches." This committee consisted of twelve persons, three each for the eastern, middle, western, and Pacific states.
