Assembly of God
Prior to 1967, the Assembles of God along with the majority of pentecostal denominations, officially opposed Christsian participation in war and considered itself a peace church.  It continues to give full doctrinal support to members who are led by religious conscience to pacifism, as do other pentecostal denominations.
