During the early 1970s, he founded and led the groundbreaking mission team "In the Name of Jesus" (ITNOJ), which included Graham Kendrick, Stephen Maxted, Steve and Cathy Coupe and Rob Buckridge among its members. He also went on to lead British Youth for Christ, and was heavily involved in the Spring Harvest series of Christian Conferences.
Calver was programme director of Billy Graham's Mission England before leading the Evangelical Alliance of the United Kingdom from 1983 to 1997. In the latter role he was a major spokesperson for Evangelicals on both sides of the Atlantic. It was during that time that Calver and his commentaries on current issues were featured often on the BBC.
From 2005-2016, he was the senior pastor of Walnut Hill Community Church, Bethel, Connecticut, USA. For seven years he was president of World Relief and he traveled around the world, ministering to the poor and networking with churches to follow after the teachings of Jesus Christ and bring help to those in need.
He married Ruth Kirby, daughter of Gilbert Kirby, the principal of London Bible College that both he and Ruth attended.
