Jas 5:15

“Whenever some illness comes upon a man, he should hurry back to the church. Let him receive the body and blood of Christ, be anointed by the presbyters with consecrated oil and ask them and the deacons to pray over him in Christ's name. If he does this, he will receive not only bodily health but also the forgiveness of his sins.”

“And if he is in sins, they will be forgiven him. Many people, due to sins committed in the soul, are punished with sickness or even death of the body. Hence the apostle told the Corinthians, who were accustomed to receive the body of the Lord unworthily: Therefore many among you are weak and ill, and many sleep (1 Corinthians 11). If therefore the sick are in sins, and they have confessed these to the elders of the Church, and have endeavored with a perfect heart to abandon and correct them, they will be forgiven. For sins cannot be forgiven without the confession of amendment. Hence it is rightly added:”

“Extreme unction is the Sacrament of those departing from this life, preparing and disposing them for perfect health; it avails also for the removal of venial sins and for the recovery of present health, if it be expedient for the sick person. This Sacrament has efficacy both for arousing devotion and for remitting venial sins and for more easily removing the dross of sins. And because for many of the sick it is still expedient to live for the accumulation of their merits: hence it is that this Sacrament, both by invigorating the soul in good and by unburdening it from evil, frequently also alleviates from disease. And this is what blessed James says, that the prayer of faith shall save the sick person, and if he be in sins, they shall be forgiven him.”

“prayer--He does not say the oil shall save: it is but the symbol. save--plainly not as Rome says, "save" the soul. but heal "the sick": as the words, "the Lord shall raise him up," prove. So the same Greek is translated, "made (thee) whole," Mat 9:21-22. and if . . . sins--for not all who are sick are so because of some special sins. Here a case is supposed of one visited with sickness for special sins. have committed--literally, "be in a state of having committed sins," that is, be under the consequences of sins committed. they--rather, "it": his having committed sins shall be forgiven him. The connection of sin and sickness is implied in Isa 33:24; Mat 9:2-5; Joh 5:14. The absolution of the sick, retained in the Church of England, refers to the sins which the sick man confesses (Jam 5:16) and repents of, whereby outward scandal has been given to the Church and the cause of religion; not to sins in their relation to God, the only Judge.”
