Luke 19:38

That is, in the name of God the Father, although it might be taken "in His own name," since He Himself is the Lord. But His own words are better guides to the meaning when He says, I am come in my Father's name. For Christ is the Master of humility. Christ is not called King as one who exacts tribute, or arms His forces with the sword, or visibly crushes His enemies, but because He rules men's minds, and brings them believing, hoping, and loving into the kingdom of heaven. For Ho was willing to be King of Israel, to show His compassion, not to increase His power. But because Christ appeared in the flesh, as the redemption and light of the whole world, well do both the heaven and earth, each in their turn, chaunt His praises. When He is born into the world, the heavenly hosts sing; when He is about to return to heaven, men send back their note of praise. As it follows, Peace in heaven.

Above all the virtues they had seen, they said: Blessed is the King who comes in the name of the Lord. They had indeed seen many virtues of the Lord, but they were especially astonished at the resurrection of Lazarus, which had recently taken place, with the crowd bearing witness who had been with Him when He called him out of the tomb and raised him from the dead. For the prophet also came to meet him and the crowd, because they heard he had performed this sign. It should be noted, for the Savior was not coming from Galilee now for the first time, that is, five days before Passover. He had previously visited Jerusalem, as John records, during the Feast of Tabernacles in the seventh month of the previous year, and from there for six continuous months, that is, until the day of Passover when He suffered. At times, He worked signs and taught in Jerusalem; at times, He ascended the Mount of Olives; at times, expelled from Judea, He went beyond the Jordan; at times, He stayed in a city of the wilderness called Ephraim with the disciples, but never during that time did He return to Galilee. Therefore, above all the virtues they had seen Him perform over such a time, the crowds praised God, saying:

Blessed is the King who comes in the name of the Lord; peace in heaven and glory in the highest. But blessed is the King who comes in the name of the Lord is rather to be understood as in the name of the Lord, in the name of God the Father, although it can also be understood in His own name, because He Himself is the Lord. Hence, it is written elsewhere: The Lord rained from the Lord. But His words direct our understanding better, who said: I have come in the name of my Father, and you did not receive me; another will come in his own name, him you will receive (John 5). For Christ is the teacher of humility, who humbled Himself, becoming obedient to death (Philippians 2). Thus, He does not lose divinity when He teaches us humility. However, Christ is not the King of Israel to demand tribute or to arm an army with iron and to conquer visible enemies, but the King of Israel because He rules minds, because He cares for eternity, because He leads believers, hopers, and lovers into the kingdom of heaven. Therefore, the Son of God, equal to the Father, the Word by which all things were made, who wished to be the King of Israel, is a matter of condescension, not promotion, a sign of compassion, not an increase in power. For He who was called King of the Jews on earth is the Lord of the angels in heaven. But because Christ in the flesh has shone as the propitiation of the whole world, namely, of men and angels, it is fitting that heavenly and earthly things mutually sing of His praise together in His dispensation. Thus, at His birth, the armies of heavenly powers sang, praising God: Glory to God in the highest, and on earth peace to men (Luke 2), and at His triumph over the prince of this world, and His imminent return to heaven, mortals reciprocate praise: Peace in heaven and glory in the highest.
