We are followers of Jesus who teach the Bible’s ancient Jewish context and serve the marginalized in Israel and the Middle East.
where we come from
JCF's roots in this region reach back before the modern State of Israel. William L. Hull founded Zion Apostolic Mission in 1936 in British Mandatory Palestine. Le Roy M. Kopp and E. Paul Kopp acquired Hull’s ministry in 1961, first renaming it Zion Christian Mission, then Cornerstone Ministries under Charles Kopp. In 2002, Jon "Yoni" Gerrish established a new arm of this Evangelical legacy in Israel by creating Jerusalem Cornerstone Foundation (JCF), a U.S. non-profit organization dedicated to biblical study tours and charity to Israel’s needy.
where we are going
With the founding of Jerusalem Cornerstone Foundation (JCF) in 2002, Yoni Gerrish has overseen JCF’s unique vision—a biblical studies tour organization that sows a significant amount of its profits into helping others. As JCF’s Biblical Study Tour participants have discovered God’s Word in its original environment and learned about the needs of this region, some have asked to support this grassroots work. Over time, others with a heart for this Land and its peoples have also contributed to JCF’s charity outreach. Today, JCF finds itself with a humble but special calling in 21st century Israel—biblical education with a call to serve.
