In that day shall the LORD of hosts be a crown of glory, and for a diadem of beauty, unto the remnant of his people,
Read Chapter 28
Cyril of Alexandria
AD 444
The prophet expounds on the destiny of those in Israel who believed in Christ, because Israel did not perish completely, as the remnant of Israel was saved, according to the prophecy. Quite a number of people believed in Christ, and his apostles were, so to speak, the first fruit. Therefore at that time the Lord of hosts will be as a crown of hope and a diadem of glory to the remnant of his people. The Lord of hosts will crown the believers with hope and glory, that is, with hope of future blessings and with glory because they will reign with him. They will become the recipients of the highest honor and will be worthy of adoration and glory. What glory can be compared with that received in the kingdom of Christ? In another passage Isaiah also says, “You shall also be a crown of glory in the hand of the Lord and a royal diadem in the hand of your God,” since Christ will crown those who believe in him with unending glory and bless them with the most joyous hope. And the remnant of Israel will participate in all of this after the others, the Gentiles, are received in Christ. Realizing their glory in Christ, they cry to their heavenly God and Father, “O Lord, crown us with the shield of your favor.” For when it pleased their God and Father, he revealed himself as an unbroken shield and became the Christ who defends us from the arrows of the evil one and keeps his people. - "Commentary on Isaiah 3.1.28"
