CMS is a fellowship of Christian people committed to cross-cultural mission. CMS works with churches to set apart, equip and support long-term workers who cross cultures to share the gospel.

The Rev. David Sandifer and his wife Cathie, along with their children Annabelle and Josiah, are serving the Lord in Amsterdam through CMS.

David and Cathie's mission at Tyndale Theological Seminary in the Netherlands is to help raise up a new generation of European leaders to equip and renew God's church. David serves as a lecturer in Pastoral Ministry and Christian Ethics, particularly involved in equipping students to deepen their biblical worldview in response to contemporary secularism. Cathie serves in pastoral care with students and in the local church.
