From volume 5 of the works of Thomas Smyth (1808 – 1873), the following rules would help a lot of churches and Christians maintain the bond of peace. This advice is timely, even if it is around two hundred years old!
To remember that we are all subject ot failings and infirmities, of one kind or another
Matthew 7:1 – 5; Romans 2:21 – 23.
To bear with and not magnify each other’s infirmities.
To pray one for another in our social meetings, and particularly in private.
To avoid going from house to house, for the purpose of hearing news, and interfering with other people’s business.
Always to turn a deaf ear to any slanderous report, and to allow no charge be brought against any person until well founded and proved.
If a member be in fault, to tell him of it in private, before it is mentioned to others.
To watch against shyness of each other, and put the best construction on any action that has the appearance of opposition or resentment.
To observe the just rule of Solomon, that is, to leave off contention before it be meddled with.
