 Earlier, a schism arose during and after World War I between Seventh-day Adventists in Germany who agreed to serve in the military if conscripted and those who rejected all participation in warfare—the latter group eventually forming a separate church (the Seventh Day Adventist Reform Movement).In the early Christian Church followers of Christ refused to take up arms.After the Roman Empire officially embraced Christianity, the Just War theology was developed in order to reconcile warfare with Christian belief.
