Isaiah 56:7 Douay-Rheims

I will bring them into my holy mount, and will make them joyful in my house of prayer: their holocausts, and their victims shall please me upon my altar: for my house shall be called the house of prayer, for all nations.

“It is written in the prophet Isaiah, "My house will be called a house of prayer among all nations." But perhaps the Jews will say that the house of God, that is, the synagogue, is open to all. We will not argue the point, except to say that the circumcised always appeal to the law. For their law is of the manner of Abraham's circumcision. Nothing new is to be seen in what the prophet gives. But if only worthless things can be found, who will say that the prophet is speaking unnecessary and empty words? I do not know whether it is prudent to listen and not to prohibit. For since the Jewish people because of their sins, which took them away from God, were asking requests from idols, they were often rebuked by the prophets. They did not want to walk the road of penitence and return to God; to their shame he signals his house is open to all nations for prayer and that since the Jews have abandoned it, he will put others in their place. For if the nations were always being admitted to the law, as the Jews claim, how was the prophet speaking of the future, unless that signified something other than had already been commanded? For it would not be possible to speak of such things as happening every day, since they were yet to come.”

“Thus says the Lord. Here, after he had promised liberation from evils, he begins to promise salvation in the conferring of goods. And it is divided into three parts. In the first is set down the preparation for salvation; in the second, the promise of salvation, chapter 60: Arise, be enlightened; in the third, the great discernment of the salvation conferred, chapter 63: Who is this. The first into two. In the first is set down the preparation on the part of the one receiving salvation; in the second, on the part of the one saving, chapter 59: Behold, it is not shortened. The first into two. In the first he gives the wholesome counsel of preparation; in the second he excludes the vain remedy, chapter 58: Cry, cease not. The first into two. In the first he sets down the diversity of those who receive the counsel, as regards the establishment of rewards; in the second, as regards the escape from dangers, chapter 57: the just man perishes. The first into three. In the first he sets down the counsel; in the second, the fruit of the counsel in those who receive it, Blessed is the man who does; in the third, the failure of salvation in those who despise it, all you beasts. Concerning the first he does two things. First he counsels the due preparation: keep judgment, you prelates, whose office it is to judge; do justice, you subjects, that is, every virtue, according as one is conformed to another by the precepts of the law. Micah 6: I will show you, O man, what is good. Second he promises the nearness of salvation: for near, that is, close, is my salvation, because you will be saved by me after the captivity, and my justice, as regards the enemies of whom I will avenge you. Above, 46: I have brought my justice near. Blessed is the man. Here he sets down the fruit of the counsel in those who receive it: and first he sets down its usefulness, setting down the fruit of fulfillment: blessed is the man who does, fulfilling in deed, who lays hold, vigorously undertaking. Psalm 111: blessed is the man who fears the Lord; and the manner of fulfilling, as regards ceremonial matters, keeping the sabbath: for the observance of the sabbath was moral as regards this, that rest is placed in God, and that one is at some time free for divine things by abstaining from other things; but it was ceremonial as regards the determination of the time. Now the seventh day was determined for them on account of the work of creation, than which nothing more worthy had yet preceded. For us, the first day, or the eighth, on account of the mystery of the resurrection, by which nature once founded is repaired for the better. Exodus 20: remember to keep holy the sabbath day. Jeremiah 17: keep your souls. And as regards moral matters, keeping the hands. Psalm 25: I will wash my hands among the innocent. Second he sets down the universality of its usefulness, and let him not say: and first he excludes the despair of certain ones who seemed unworthy, whether on account of a defect of lineage, because they were not of the race of Israel. Who adheres, keeping his precepts. By separation, not making me a partaker of the salvation promised to them. Romans 10: for there is no distinction of Jew and Greek: for the same is Lord of all. Or on account of a defect of the generative power: and let not the eunuch say: a dry tree, powerless to beget, as a dry tree is powerless to sprout. Proverbs 11: the just, like a flourishing leaf. Second he sets down the promise: for thus says the Lord. And first to them specially, as regards the eunuchs: they shall have kept, as regards the worship of religion; they shall have chosen, as regards obedience to the law; they shall have held fast, as regards the observance of the promise of abstaining from evils: within the walls, that is, a dwelling within the walls of my city; a better name, in that they shall be called my servants and holy ones; and than sons, as if they had begotten many sons. Wisdom 3: the eunuch who has not wrought. And as regards the strangers: and to sons, that is, I will give the privileges in which the Jews glory, that they may worship, as regards special worship, and love, as sons, that they may be as servants, and glory in his dominion. Above, 19: they shall worship the Lord. And these things indeed were fulfilled in the return of the people from the captivity; but more fully in the conversion of the nations to the faith of Christ, as the Gloss explains. Second, as regards all in general: every one who keeps. And concerning this he does two things. First he sets down the promise, by which he promises the restoration of the sacred place: to the holy mountain. Namely, as above, 1: come, let us go up to the mountain of the Lord. And as regards the acceptance of sacrifices: holocausts. Malachi 3: the sacrifice of Judah and Jerusalem shall be pleasing to God. Second he sets down the order of fulfillment: and first as regards the veneration of the temple: for my house. 2 Maccabees 3: the temple throughout the whole. John 2 and Matthew 21: my house shall be called a house of prayer. Second, as regards the gathering of the people: says the Lord, to him; he gathers Israel, the nations adhering to him. Psalm 146: the Lord, building up Jerusalem, will gather the dispersions of Israel. Note on that word, and I will give a better name, that the saints have a name, first from predestination. Above, 49: the Lord has called me from the womb; second, from divine attainment. 1 John 3: behold what manner of love or charity God the Father has given us, that we should be called, and should be, sons of God. Third, from the infusion of grace. Apocalypse 2: you have a name, and you hold my name. Fourth, from the renewal of the mind. In the same place, Apocalypse 2: I will give a stone. Also note, that the name of God is to be loved: first, because it is great, so as to be feared. Malachi 1: my name is great among the nations, says the Lord. Second, because it is holy, so as to be venerated. Luke 1: he who is mighty has done great things for me, and holy is his name. Third, because it is sweet, so as to be meditated upon. Above, 26: your name and your memorial are in the desire of the soul. Fourth, because it is abundant, so as to show mercy. Canticle 1: your name is oil poured out. Fifth, because it is efficacious, so as to obtain. John 15: whatsoever you shall ask the Father in my name, he will give you. Sixth, because it is powerful, so as to save. Acts 4: there is no other name under heaven whereby we must be saved. Seventh, because it is hidden, so as to be known. Proverbs 30: what is his name. All you beasts of the field. Here he threatens those who despise it with the failure of salvation: and first he designates the punishment of slaughter: all beasts, to devour, their corpses. Ezekiel 39: speak to every bird, to all. Second he sets down the fault: and first, of the prelates, as regards their failure in government and in foreseeing dangers. Watchmen: for prelates are set up to guard the people from dangers, as a watchman guards against enemies: they have not known, to foresee dangers. Matthew 15: let them alone: they are blind leaders of the blind. In the correction of vices, all of them dogs. To bark, against vices. Psalm 37: but I, as a deaf man, heard not, and as a dumb man, not opening his mouth. In the admonition of things to be done, seeing vain things, promising them prosperous things when adverse things were imminent; and thus nourishing them in sins. Ezekiel 22: her prophets daubed them. In the plundering of goods, and most shameless dogs; as if, without any restraint of shame, despoiling their subjects of their goods, and never satisfied. Psalm 58: they shall suffer hunger like dogs. And as regards their failure in the perfection of knowledge: they, the shepherds, understanding, of the law and the prophets. Proverbs 1: the intelligent man shall possess the helm. Psalm 81: they have not known nor understood; they walk on in darkness. Second, the fault of the subjects, or of all in common: and first, as regards their own will, which pertains to pride: all, into his own way. Jeremiah 16: every one walks. Second, as regards their covetousness, which pertains to avarice: every one. Jeremiah 6: from the least even to the greatest, all are given to avarice. Third, as regards pleasure, which pertains to the concupiscence of the flesh: come. And it shall be; that is, if today we rejoice in such things, tomorrow much more. Above, 22: and behold joy and gladness, killing calves and slaying rams, eating flesh and drinking wine.”

“Even them will I bring to my holy mountain,.... The church, called a "mountain" for its height, visibility, and immovableness; see Isa 2:2, especially for the latter; the true members of it being such who are interested in the unchangeable love of God, in the immovable grace of election, in the unalterable covenant of grace, are on the Rock Christ Jesus, and are secured by the favour and power of God; and it is called a "Holy One", because in it holy men are, holy doctrines are preached, holy services performed, and the holy God, Father, Son, and Spirit, grant their presence: and hither the Lord "brings" his people; he shows them the way thither; he inclines their minds, and moves their wills, to come hither; he removes the objections that are in their way; he constrains them by his love; and he does it in a very distinguishing way, takes one of a city, and two of a family, and brings them hither; and he who says this is able to do it; and, when he has brought them there, will do for them as follows: and make them joyful in my house of prayer; or "in the house of my prayer" (p); not made by him, as say the Jews (q); but where prayer is made unto him, and is acceptable with him; every man's closet should be a place of private prayer; and every good man's house a place of family prayer; but a church of God is a house where saints meet together, and jointly pray to the Lord: and here he makes them joyful; by hearing and answering their prayers; by granting his gracious presence; by discovering his love, and shedding it abroad in their hearts; by feeding them with his word and ordinances; by giving them views of Christ, his love and loveliness, fulness, grace, and righteousness: by favouring them with the consolations of his Spirit, and his gracious influences; and by showing them their interest in the blessings of grace and glory: their burnt offerings and their sacrifices shall be accepted upon mine altar: which is Christ, who is not only the priest that offers up all the sacrifices of his people, but is also the altar on which they are offered up, Heb 13:10, and is the only One, and the most Holy One, which is greater than the gift, and sanctifies every gift that is upon it, and makes both the persons and the offerings of the Lord's people acceptable unto God; for by these offerings and sacrifices are not meant legal but spiritual ones; good deeds, acts of beneficence, rightly performed, with which sacrifices God is well pleased; sacrifices of prayer and praise; and even the persons of saints themselves, their bodies and their souls, when presented, a holy, living, and acceptable sacrifice unto God, Heb 13:15, the prophet here speaks in figures, agreeably to his own time, as Calvin observes, when speaking of Gospel times; so he makes mention of the sabbath before, instead of the Lord's day, or any time of worship under the Gospel dispensation: for mine house shall be called a house of prayer for all people; Gentiles as well as Jews; the sons of the strangers, as others, are all welcome to the church of God, to come and worship, and pray to the Lord there, and that is in any place where the saints meet together; for holy hands may be lifted up everywhere, without wrath or doubting, Ti1 2:8. The Jews apply this verse to the time when the son of David, the Messiah, shall come (r). (p) "in domo orationis meae", V. L. Vatablus, Pagninus, Montanus, Vitringa. (q) T. Bab. Beracot, fol. 7. 1.

“Prayer. So the temple is justly styled. (Haydock) — This shall be open to all nations. After the captivity, the Jews condescended to let the Gentiles have a court, and they even suffered some princes to go into the court of the priests, 2 Machabees iii. 33. Physcon wished to penetrate into the inner sanctuary, (3 Machabees; Ecclesiasticus l.) which could not be granted.”

“Jer. 7 : 11 ; Matt. 21 : 13; Mark 11 : 17 ; Luke 19 : 46. The universal character of the Church is clearly stated. Prayer is her essential worship, the offering of sacrifice being its sublimest form.”

“Even them-- (Eph 2:11-13). to my holy mountain--Jerusalem, the seat of the Lord's throne in His coming kingdom (Isa 2:2; Jer 3:17). joyful-- (Rom 5:11). burnt offerings . . . sacrifices--spiritual, of which the literal were types (Rom 12:1; Heb 13:15; Pe1 2:5). accepted-- (Eph 1:6). altar-- (Heb 13:10), spiritually, the Cross of Christ, which sanctifies our sacrifices of prayer and praise. house . . . for all people--or rather, "peoples." No longer restricted to one favored people (Mal 1:11; Joh 4:21, Joh 4:23; Ti1 2:8). To be fully realized at the second coming (Isa 2:2-4). No longer literal, but spiritual sacrifice, namely, "prayer" shall be offered (Psa 141:2; Psa 51:17; Mal 1:11; Mat 21:13).”
