Anointing...
The Brethren do anointing as an ordinance of the church because we are obedient to scripture. In this text we are told to anoint the sick with oil and pray for them. It is an act of obedience. It is an act of the community surrounding the person in need. It is an act of confession. It is an act of prayer. People who experience anointing often say that it brings them a deep sense of peace for whatever lies ahead.
From James 5:13-16:
Are any among you suffering? They should pray. Are any cheerful? They should sing songs of praise. Are any among you sick? They should call for the elders of the church and have them pray over them, anointing them with oil in the name of the Lord. The prayer of faith will save the sick, and the Lord will raise them up; and anyone who has committed sins will be forgiven. Therefore confess your sins to one another, and pray for one another, so that you may be healed. The prayer of the righteous is powerful and effective.
