178:1.2

The kingdoms of this world, being material, may often find it necessary to employ physical force in the execution of their laws and for the maintenance of order. In the kingdom of heaven true believers will not resort to the employment of physical force. The kingdom of heaven, being a spiritual brotherhood of the spirit-born sons of God, may be promulgated only by the power of the spirit. This distinction of procedure refers to the relations of the kingdom of believers to the kingdoms of secular government and does not nullify the right of social groups of believers to maintain order in their ranks and administer discipline upon unruly and unworthy members.
