The ministry of healing is given to the elders of the church. Healing and forgiveness go together in the atonement.

James 5:14-15  "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."
