- Is any sick among you? let him call for the elders of the church; and let them pray over him, anointing him with oil in the name of the Lord:
- And the prayer of faith shall save the sick, and the Lord shall raise him up; and if he have committed sins, they shall be forgiven him (James 5:14, 15).
"It is the oil and not the container that is being consecrated, and there is no impropriety in consecrating the oil in a large container and thereafter pouring it into smaller vessels. A good grade of olive oil should be used, and after it has been consecrated, it should not be commingled (mixed) with any ointments or used indiscriminately." 
[Elder]]s in the Church keep consecrated oil at hand for emergencies, and small vials are available that can be attached to key chains. When consecrated oil is employed for the healing of the sick, there are usually two elders involved. One elder administers the oil (a drop of which is placed upon the head of the sick person), and invokes the Lord's power on behalf of the sick. The second elder pronounces a blessing of healing and comfort.
