Chrysostom says: "The Apostle did not speak these words without cause. It was because, accusing God, they said that those who had been deemed worthy to be called sons of God were being driven out and deprived of honor.
They had received the Law, had known God before all other nations, had enjoyed special glory, and had served God when no one else yet served Him.
They had received the promises and, what is most important, had become the forefathers of Christ Himself. This is what the words mean: 'from whom is Christ according to the flesh.'
They said that, in place of them, people from the Gentiles were being brought in, people who had never known God.
Since those who said this blasphemed God, Paul was torn when he heard it. He grieved over God's glory and wished to be separated, if this were possible, if only the Jews might be saved.
Then blasphemy would cease, and no one would remain in the thought that God had deceived their forefathers, to whom He had promised gifts.
Paul wished to be separated, so that you might know how deeply he was crushed by the thought that could have settled in many minds, namely, that God's promise had remained unfulfilled."
Yet by thus cleansing his grief and heart's pain from merely natural motives, and by sanctifying the birth of it through divine providential orders, the Apostle had another aim no less.
He wished to stir in the hearts of the Jews sorrow over the loss of so many privileges, and to draw them to faith in Christ, without which they could not be preserved.
It is as though, without saying it, he says to them: such great privileges! And all this is being lost because of your single unwillingness to believe in the Lord.
Pity yourselves, then, and come to the Lord and Savior.
Ambrosiaster writes: "The Apostle enumerates such high privileges of the Jews, and the glorious promises given to them, in order to awaken painful regret for this in all of them.
For by not receiving Christ, they lost the privileges of the fathers and were deprived of the promises. Thus they became worse than the Gentiles, whom they formerly despised as being without God.
For it is more bitter to lose dignity than not to have it."
"Who are Israelites." "For this name also was illustrious, since it was given by God to the forefather and passed to his descendants as an inheritance" (Blessed Theodoret).
This name was given to Jacob after he remained until morning in struggle with the One who appeared to him. Therefore He said to him: "Your name shall no longer be called Jacob, but Israel shall be your name.
For you have prevailed with God, and you shall be strong with men" (cf. Gen 32:28).
This name signifies one who beholds God, stands under God's protection, and is strong among men by His blessings. For this reason it was honored by all.
When the Lord saw Nathanael, He honored him with this name, saying: "Behold, truly an Israelite, in whom there is no guile" (cf. Jn 1:47).
Saint Paul, needing to show that he was not lower than others, says: "Are they Israelites? So am I" (cf. Phil 3:5).
When later Judaism fell into decline, Christians gloried in this name, calling themselves the new Israel.
"To whom belongs the adoption." "For they received this name also, since it is said: 'Israel is My firstborn son' (Ex 4:22)" (Blessed Theodoret).
Thus the Lord God called the people of Israel in His threat to Pharaoh. Because Pharaoh oppressed this people as His firstborn, God resolved to take the firstborn of the king and of all the Egyptians.
A son is dear, and a firstborn son even more so. The Israelites were honored with this name because God chose them from all the nations and made them His own.
They were to compose, as it were, His household. Therefore Moses says in Deuteronomy: "You are sons of the Lord your God.
For you are a holy people to the Lord your God, and the Lord your God has chosen you to be a chosen people for Himself from all nations on the face of the earth" (cf. Deut 14:1-2).
Having chosen them, God also had special care for them as His own, as children.
"And the Lord's portion became His people, Jacob the lot of His inheritance. He satisfied him in the wilderness and kept him as the apple of His eye.
As an eagle covers its nest and longs over its young, He spread His wings, received them, and bore them on His shoulders" (cf. Deut 32:9-11).
Therefore, when the Israelites proved faulty before God, God reproached them thus: "I have begotten and exalted sons, but they have rejected Me" (Isa 1:2).
But this adoption, being outward, was a type of that true and essential sonship of which Christians are deemed worthy.
They are born of God by the Holy Spirit and clothed in Christ, the Son of God, who was well pleased to become our brother through the Incarnation.
"And the glory." "For they became glorious through miracles" (Blessed Theodoret).
Since glory is placed here among the special privileges of the people of Israel, it must be understood here as something particular.
It is the visible sign of God's presence among this people. The first of such signs was the pillar of cloud, which guided them by day and shone like fire by night (cf. Ex 13:21).
This continued throughout their wandering in the wilderness. The second was the glory of God that descended upon Mount Sinai and covered it (cf. Ex 24:16).
The third was the cloud that covered the tabernacle of witness at the moment of its consecration, when that tabernacle was filled with the glory of the Lord (cf. Ex 40:34).
This was repeated at the consecration of the temple built by Solomon. It showed that replacing the tabernacle with the temple had not changed God's presence among them (cf. 1 Kgs 8:11).
The constant sign of God's presence among the Israelites was the ark of the covenant, overshadowed by Angels, from whose midst God gave His answers (cf. Ex 25:22).
Therefore, when the ark of the covenant was taken by the Philistines, the people cried out in weeping: "The glory of God has departed from Israel, because the ark of the Lord has been taken" (cf. 1 Sam 4:21).
The ark returned, and with it the glory of God. When the holy prophet David spoke of the tabernacle, he called it the dwelling place of God's glory because of the ark present in it.
"O Lord, I have loved the beauty of Thy house, and the place where Thy glory dwells" (cf. Ps 26:8).
When he came into the temple, he said: "I appeared before Thee in the sanctuary, to behold Thy power and Thy glory" (cf. Ps 63:2).
"And the covenants." "For God promised to give them not only the Old Covenant, but also the New.
It is said: 'I will make a new covenant with the house of Israel, not according to the covenant which I made with their fathers' (cf. Jer 31:31-32).
But they themselves did not wish to receive the latter covenant" (Blessed Theodoret).
Although they did not receive it when the time came for it to enter into force, they did receive it in promise and awaited its arrival.
Therefore the New Covenant also belongs to them. Their nonacceptance of it is equivalent to violations of what had been received, and likewise makes them guilty before God.
However, those who wish may understand by the covenants the one Old Covenant, renewed many times.
It was given to Abraham, repeated to Isaac and Jacob, solemnly proclaimed to the whole people, and afterward restored more than once because of the people's frequent violations.
"And the giving of the Law." "Because the Law of Moses was given to them" (Blessed Theodoret).
The Law was a great benefit for the people. It defined in detail family life, civil life, relations with other nations, and, most importantly, it bound the whole people into one.
It proclaimed God as their king. When necessary, He revealed His will from the midst of the mercy seat above the ark.
In the hour of need, He defended His people with a strong hand and a high arm.
"And the service." "Because, preferring them to other nations, He taught them the lawful priestly service" (Blessed Theodoret).
The ranks of service to God belong to the content of the Law. There all deeds and laws were established and received as service to God.
The Apostle separated it from the general giving of the Law and mentioned it specially, because citizenship and the other orders of life and government took on another form after the establishment of kings.
Then divine worship remained, above all, the service of God. Especially toward the end, it alone served as the distinctive mark of the people of Israel from other nations.
If we keep in mind the Apostle's aim, to draw men in every way to Christ the Lord, then we may suppose why he mentioned the service separately.
All its ranks were a shadow of the body of Christ.
"And the promises." "Both those given by God to the fathers and those proclaimed by the Prophets" (Blessed Theodoret).
They were given to the fathers, Abraham, Isaac, and Jacob, and to all the Prophets, beginning with Moses and ending with Malachi.
The object of the promises is the Messiah and His Kingdom. In the prophetic utterances, everything belonging to this is defined in detail.
Only the blindness of those who governed the people, and their deviation toward worldly aims, prevented them from recognizing the promised One in the Savior who appeared.
