He was chairing the National Assembly of Evangelicals in 1966, a convention organised by the Evangelical Alliance, when Martyn Lloyd-Jones made an unexpected call for evangelicals to unite as evangelicals and no longer within their "mixed" denominations. This view was motivated by a belief that true Christian fellowship requires evangelical views on central topics such as the atonement and the inspiration of Scripture. Lloyd-Jones was a key figure to many in the free churches, and evangelical Anglicans regarded Stott similarly. The two leaders publicly disagreed, as Stott, though not scheduled as a speaker that evening, used his role as chairman to refute Lloyd-Jones, saying that his opinion went against history and the Bible. The following year saw the first National Evangelical Anglican Congress, which was held at Keele University. At this conference, largely due to Stott's influence, evangelical Anglicans committed themselves to full participation in the Church of England, rejecting the separationist approach proposed by Lloyd-Jones.
