Fifty-two men served on the committee of the London Union on Church Matters (LUCM) for all or part of its existence. Of these, twenty-nine were laymen and twenty-three clerics. Nine of the fifty-two converted to Rome a few years after the union was formed—six of them laymen and three clergymen—and by leaving the Church, they also left the LUCM. Committee members varied in their levels of engagement in union business, their influence in decision making, their reputations in the Church and outside it, and their preferences in goals and tactics, but for the most active committee men, the vanguard of the church union movement, the LUCM represented a new and necessary initiative that would change the Church for the better and make it stronger politically and socially.
