We can exclude them, drive them forth, and turn a deaf ear to them. We are divided over more than a score of things. Regardless of how right we may be about those things we are wrong to be divided from our brethren. There is no authority in God's word to separate from our brethren. Those who claim to recognize God's word as authority should show that passage where God demands that we divide the body of believers.
Every command is to live in harmony and to maintain unity.
It is as wrong to put away our brothers for every cause as it is for a man to put away his wife for every cause. The same God who decreed in the first creation that a man and wife should be one flesh, has decreed in the new creation that we all be one spirit. It is as sinful to rend the fabric of the spiritual family as to destroy that of the fleshly family. To maintain domestic union we must make allowances for each other, we must be patient and longsuffering. So long as love exists we do not separate regardless of how difficult our problems become.
