The Lord proclaims that He will come to you in judgement, swiftly reproving the wicked, the adulterers, and those who invoke My name deceitfully, who exploit workers, oppress widows, disregard orphans, distort justice toward the foreigner, and do not fear Me, says the Lord Almighty; for I am your God, and I do not change.
In this context, those who claim that "all who do evil are good in the Lord's sight and are accepted by Him" pose the challenge: "Where is the God of justice?" To address this, the Lord responds: "I will send My messenger to prepare the way before Me, and the Lord you seek, the true Judge, will come to His temple." This is echoed in the Psalm: “O God, give Thy judgement to the king and Thy righteousness to the king's son,” for "the Father judges no man but has entrusted all judgement to the Son" (John 5:22). He is the Angel of the covenant you seek, to whom evil is not welcome, who, in judgement, does not show favoritism (Col. 3:25). His nature is unchangeable, unmoved by mercy or severity, for in the Lord's hand is a cup full of pure wine, balanced perfectly between mercy and justice.
He will swiftly return to His temple, which signifies the Church. Who can comprehend the day of His coming? Given His immense power, who can endure Him? Who will be able to see Him, even with half-closed eyes, and behold the brilliance of the Sun of righteousness, who brings salvation on His wings? He will come like refining fire and like the detergent used by launderers, as fire engulfs His face and a fierce storm surrounds Him (Psalm 49:4). Then He will summon heaven and earth to witness His judgement of His people, and streams of fire will consume all sinners as they stand before Him. The Lord is described as a consuming fire (Deuteronomy 4:11, 12), much like dry hay or straw.
But He is not only fire; He is also the cleanser’s lye, referred to in Hebrew as borith, and the Seventy translate it as πόαν from πόα, which means the herb used by launderers. He acts as fire that refines and purifies those who have grievously sinned, and as the cleansing herb for those who have committed lesser transgressions. This is in line with what is written in Isaiah: "The Lord will wash away the filth of the sons and daughters of Zion and cleanse their blood from their midst by the Spirit of judgement and the Spirit of fire" (Isaiah 4:4). Those who bear uncleanness require the Spirit of judgement for cleansing, while those covered in blood need the Spirit of fire to purify them from their sins.
He will sit as one who refines and purifies silver, as stated in the prophecy of Ezekiel, so that all impurities in our gold and silver, representing our thoughts and words mingled with dross, might be consumed in the refining fire of the Lord, resulting in pure gold and silver. Hence, the Lord declares in the Gospel, "I have come to cast fire upon the earth, and how I wish it were already kindled" (Luke 12:49). He will purify the sons of Levi, affirming that the time has come for judgment to begin within the house of God (1 Peter 4:17), as it is said: "Begin with My holy ones" (Ezekiel 9:6).
The sons of Levi represent every priestly office. If the priests require cleansing to ensure that pure gold and silver remains, what then can be said about others? Upon their cleansing, they will offer righteous sacrifices to the Lord, which will be accepted by the priesthood of God for Judah and Jerusalem—those who earnestly confess to the Lord and seek His peace. Just as in days gone by, when their sacrifices were initially pleasing to God, so too, after repentance, shall they again be found acceptable, having been purified from all impurity.
"I will come to you in judgement," He assures, "and will be a swift reprover." What a terrifying judgement it will be when He Himself is both the exposer and the judge; an exposer for all evildoers and adulterers, as such sins, hidden in darkness, will be brought into the light. He addresses the adulterers, those who swear falsely, and those who deceitfully calculate the wages of laborers, unwilling to compensate them fairly. The implied oppression of widows and orphans, the mistreatment of strangers, and the disregard for the foreigner—those still seeking citizenship in the kingdom of Christ—are also condemned. Even if not all these acts are committed, one sin, the lack of the fear of God, is sufficient to warrant judgement. Thus, we cannot regard false oaths, underpayment, mistreatment of orphans and widows, or oppression of the stranger as mere trivialities; these are serious transgressions equating to wickedness, deceit, and adultery.
What is expressed applies both to historical events and to the current condition of leaders within the Church, echoing what was once said to the Jewish rulers. The statement, "I am the Lord, and I change not," emphasizes that while He presents Himself as refining fire or cleansing herb, His divine nature remains unaltered even in manifestations as an angel or through elemental imagery.
