In 1977, "The Chicago Call" was issued by the National Conference of Evangelicals for Historic Christianity, meeting in Warrenville, Illinois. Led by Robert E. Webber (Assoc. Professor of Theology at Wheaton College), along with Peter Gillquist, Thomas Howard, Richard Holt, Donald Bloesch, Jan Dennis, Lane Dennis, and Victor Oliver, the conference discussed the need for Evangelical Protestants to rediscover and re-attach to the Christian Church's historic roots. The conference issued several documents which together are known as "The Chicago Call". Components of the document include: "A Call to Historic Roots and Continuity; A Call to Biblical Fidelity; A Call to Creedal Identity; A Call to Holistic Salvation; A Call to Sacramental Integrity; A Call to Spirituality; A Call to Church Authority; and A Call to Church Unity".
