Rick Warren

===Purpose Driven===
Warren taught the material that would one day become the Purpose Driven philosophy of ministry to individual pastors who called or wrote him in Saddleback's early days.

Warren gained experience teaching the material through his participation in the Institute for Evangelism and Church Growth, affiliated with Fuller Theological Seminary.

In 1995 [[Zondervan]] published Warren's best-selling book, ''[[The Purpose Driven Church]]'', which distilled many of the lessons he had learned while starting Saddleback Church and honed during years of training other pastors.<ref>Dr Alan Rathe, ''Evangelicals, Worship and Participation: Taking a Twenty-First Century Reading'', Ashgate Publishing, USA, 2014, p. 149</ref> After sharing the "Saddleback Story", the book makes a case for building a church around five purposes (worship, fellowship, discipleship, ministry, and evangelism) through what Warren called a "crowd to core" method of church growth.<ref>Randall Herbert Balmer, ''Encyclopedia of Evangelicalism: Revised and expanded edition'', Baylor University Press, USA, 2004, p. 721-722</ref> He encouraged churches to reach their community, bring in a crowd, turn attendees into members, develop those members to maturity, turn them into ministers, and send them out on a mission.

In 2004, more than 10,000 churches of various denominations attended a seminar or a conference led by Warren.<ref>{{cite magazine|first=Sonja|last=Steptoe|url=http://content.time.com/time/magazine/article/0,9171,603246,00.html|title=The Man With The Purpose|magazine=Time|date=March 21, 2004|access-date=February 8, 2022}}</ref>
