Charles Simeon’s ministry to students included sermons, classes and discussion groups which provided the only training then available for ordinands. His preaching was particularly notable, his declared aim being ‘to humble the sinner, exalt the Saviour, and promote holiness.’ In 1794 Simeon introduced into the church a barrel-organ with sixty hymn tunes to assist the congregation with their singing. Simeon also had a deep concern for Missions and raised up several missionaries. He was one of the founders of the Church Missionary Society in 1799.
