A minister of the Word may be loaned temporarily by the calling church to serve as pastor of a congregation outside of the Christian Reformed Church, but only with the approval of classis, the concurring advice of the synodical deputies, and in accordance with the synodical regulations. Although the specific duties may be regulated in cooperation with the other congregation, the supervision of doctrine and life rests with the calling church.
