Isaiah 62:3Meaning & Commentary from the Church Fathers

In response to this promise, the Church proclaims, I will rejoice in the Lord with gladness, in the third Psalm of the third degree, on behalf of the repentant community, joyfully singing, I am glad for those who said to me, Let us go to the house of the Lord (Ps. 121:1). The prophet reiterates, For the sake of Zion, I shall not be silent, and for the sake of Jerusalem, I shall find no rest. Day and night, he asserts, I will not close my mouth, and my voice will never be hushed; I will cry out and attach my pleas until the Promised One arrives, illuminating the entire world with His glory. It is clear who is sought after, the One whose coming is longed for; He is to be revealed as the dawning light. His righteousness shall shine forth as a beacon, and His salvation will glow like a lamp. He who proclaimed in the Gospel, ‘I am the light of the world’ (John 8:12), although He was ignited in Zion and Jerusalem, His light will not be confined to Judea alone; it will be proclaimed, ‘The light within you has been kindled; having emerged from the Father, He has begun to shine within your lands and will enlighten all nations.’ All kings, O Jerusalem and Zion, shall behold your glorious One, born of your lineage, who, when lifted up on the cross, drew all unto Himself. Thus, every nation will see His righteousness through which the Creator has shown mercy to them, and kings will witness His glory as He was exalted upon the cross, making all kingdoms subject to His reign. Consequently, it will no longer solely be called Jerusalem and Zion; it shall receive a new name given by God, who declared to the apostle Peter: ‘You are Peter, and upon this rock, I will build My Church, and the gates of hell shall not prevail against it’ (Matthew 16:18). This name is divine, and it shall be referred to as the Lord's Church. Its people will no longer bear the old designation of Israelite but will instead be known by the new name, Christian. It will serve as a crown in the hand of the Lord and as a royal diadem in the hand of its God, when the multitude of believers crowns it, and the diadem of authority adorned with various precious stones by the martyrs shall rest in God’s hand, enabling Him to crown His Son with their triumphs. Thus, the apostle Paul also instructed the saints, ‘Gladden and crown me’ (Philippians 4:1).

Some interpret Christ’s crown as those who have thrived through Him, while the diadem of His kingdom (Is 62:3) represents those who became martyrs for His sake, whom the Father guided to be placed upon the Son, thus crowning Him and rewarding Him with the royal diadem—the multitude saved through Him. For their benefit, she will adopt a new name and will no longer be referred to as forsaken and desolate, but rather My will (Is 62:4, LXX), indicating her alignment with His purposes. This illustrates that she, once forsaken, will be transformed into something beautiful, in place of those who denied Christ; yet the remnant that was saved has been integrated into Him... By 'will,' He refers to those who carry out His desires, of whom He expresses His love, akin to a young man devoted to a virgin (Is 62:5)... He preserves her as a virgin, reflecting the mystery Paul speaks of regarding Christ and the Church (Eph 5:32). Furthermore, he highlights the current condition of the Churches, guided continuously by the priests overseeing the people who are unfamiliar with God, which serves as an unyielding barrier (Is 62:6), safeguarding against the corruption of the adversary.
