What prophetic warnings to the wealthy and sacramental practices for the sick and penitent does Saint James present in James 5?

Saint James delivers a blistering prophetic indictment against self-indulgent, oppressive rich men, summoning them to weep and wail over the catastrophic miseries descending upon them. Their accumulated wealth has rotted into uselessness, their costly garments have been devoured by moths, and their hoarded gold and silver have corroded. The rust of their treasures will stand as an accusing testimony against them, consuming their flesh like blazing fire, for they have stored up treasures of divine wrath in the closing days of time. The wages of the agricultural laborers who reaped their fields, fraudulently withheld by their masters, cry aloud for justice, and their desperate laments have entered the ears of the Lord of Hosts. The wealthy have feasted luxuriously upon the earth, nourishing their hearts in the day of slaughter, while condemning and putting to death the Just One, who did not resist them.

Turning to the afflicted faithful, James counsels patient endurance until the coming of the Lord. He bids them observe the agrarian farmer, who waits patiently for the precious harvest of the land, persevering through hardships until the early and late rains arrive. Believers must likewise fortify their hearts in patience, for the arrival of the Lord is at hand. They must refrain from harboring bitter grudges against one another to avoid divine judgment, knowing that the eternal Judge stands right at the doorway. As inspiring models of suffering and long-suffering, let them look to the ancient prophets who spoke faithfully in the Lord’s name. The Church counts those blessed who have persevered; the brethren have heard of the famous endurance of Job and have witnessed the compassionate outcome wrought by the Lord, who is tenderhearted and abundant in mercy. Above all, they must not swear by heaven, earth, or any other swearing, letting their speech remain a simple, trustworthy yes or no to escape condemnation.

The apostle outlines the spiritual and sacramental remedies for daily Christian life. If anyone is sorrowful, let him turn to prayer; if anyone is joyful in spirit, let him sing. If anyone among them is sick, he must summon the presbyters of the Church, who shall pray over him and anoint him with oil in the name of the Lord. The prayer of faith will save the sick person, the Lord will raise him up, and if he has committed sins, they will be forgiven. A Challoner annotation notes that this passage provides an explicit scriptural warrant for the sacrament of Extreme Unction, stating that controversy against its institution opposes the express words of this passage.

James further instructs the faithful to confess their sins and pray for one another that they may be saved. A second Challoner annotation explains that this confession of sins is made to the ordained priests of the Church, whom verse 14 directs the sick to summon. The annotation says confession to others without power to forgive would be useless, and distinguishes God’s appointment of ordained ministers with jurisdiction to remit sins in his name. To demonstrate the power of prayer, James recalls the prophet Elijah: though a mortal man subject to human frailties like ourselves, he prayed earnestly that rain might cease, and no rain fell upon the earth for three years and six months; and when he prayed again, heaven poured down rain and the earth yielded its fruit. In closing, the apostle reminds the community of the immense value of pastoral rescue: whoever converts a wandering sinner from his mistaken way saves his soul from death and covers a multitude of sins.
