Ps 118, 24 This is the day the LORD has made

(Ps 118, 24) This is the day the LORD has made

[24] This is the day the LORD has made; let us rejoice in it and be glad

(CCC 2171) God entrusted the sabbath to Israel to keep as a sign of the irrevocable covenant (Cf. Ex 31:16). The sabbath is for the Lord, holy and set apart for the praise of God, his work of creation, and his saving actions on behalf of Israel. (CCC 348) The sabbath is at the heart of Israel's law. To keep the commandments is to correspond to the wisdom and the will of God as expressed in his work of creation. (CCC 349) The eighth day. But for us a new day has dawned: the day of Christ's Resurrection. The seventh day completes the first creation. The eighth day begins the new creation. Thus, the work of creation culminates in the greater work of redemption. The first creation finds its meaning and its summit in the new creation in Christ, the splendour of which surpasses that of the first creation (Cf. Roman Missal, Easter Vigil 24, prayer after the first reading). (CCC 2175) Sunday is expressly distinguished from the sabbath which it follows chronologically every week; for Christians its ceremonial observance replaces that of the sabbath. In Christ's Passover, Sunday fulfills the spiritual truth of the Jewish sabbath and announces man's eternal rest in God. For worship under the Law prepared for the mystery of Christ, and what was done there prefigured some aspects of Christ (Cf. 1 Cor 10:11): Those who lived according to the old order of things have come to a new hope, no longer keeping the sabbath, but the Lord's Day, in which our life is blessed by him and by his death (St. Ignatius of Antioch, Ad Magn. 9, 1: SCh 10, 88).

Ps 118, 22 The stone the builders rejected

(Ps 118, 22) The stone the builders rejected

[22] The stone the builders rejected has become the cornerstone.

(CCC 587) If the Law and the Jerusalem Temple could be occasions of opposition to Jesus by Israel's religious authorities, his role in the redemption of sins, the divine work par excellence, was the true stumbling-block for them (Cf. Lk 2:34; 20:17-18; Ps 118:22). (CCC 756) "Often, too, the Church is called the building of God. The Lord compared himself to the stone which the builders rejected, but which was made into the comer-stone. On this foundation the Church is built by the apostles and from it the Church receives solidity and unity. This edifice has many names to describe it: the house of God in which his family dwells; the household of God in the Spirit; the dwelling-place of God among men; and, especially, the holy temple. This temple, symbolized in places of worship built out of stone, is praised by the Fathers and, not without reason, is compared in the liturgy to the Holy City, the New Jerusalem. As living stones we here on earth are built into it. It is this holy city that is seen by John as it comes down out of heaven from God when the world is made anew, prepared like a bride adorned for her husband (LG 6; cf. 1 Cor 3:9; Mt 21:42 and parallels; Acts 4:11; 1 Pet 2:7; Ps 118:22; 1 Cor 3:11; 1 Tim 3:15; Eph 2:19-22; Rev 21:3; 1 Pet 2:5; Rev 21:1-2).

Ps 118, 14 The LORD my strength and might

(Ps 118, 14) The LORD my strength and might

[14] The LORD, my strength and might, came to me as savior.

(CCC 1808) Fortitude is the moral virtue that ensures firmness in difficulties and constancy in the pursuit of the good. It strengthens the resolve to resist temptations and to overcome obstacles in the moral life. The virtue of fortitude enables one to conquer fear, even fear of death, and to face trials and persecutions. It disposes one even to renounce and sacrifice his life in defense of a just cause. "The Lord is my strength and my song" (Ps 118:14). "In the world you have tribulation; but be of good cheer, I have overcome the world" (Jn 16:33).

Ps 116, 12-13. 17 I will offer a sacrifice of thanksgiving

(Ps 116, 12-13. 17) I will offer a sacrifice of thanksgiving

[12] How can I repay the LORD for all the good done for me? [13] I will raise the cup of salvation and call on the name of the LORD. [17] I will offer a sacrifice of thanksgiving and call on the name of the LORD.

(CCC 224) It means living in thanksgiving: if God is the only One, everything we are and have comes from him: "What have you that you did not receive?" (1 Cor 4:7). "What shall I render to the LORD for all his bounty to me?" (Ps 116:12). (CCC 1330) The memorial of the Lord's Passion and Resurrection. The Holy Sacrifice, because it makes present the one sacrifice of Christ the Savior and includes the Church's offering. The terms holy sacrifice of the Mass, "sacrifice of praise," spiritual sacrifice, pure and holy sacrifice are also used (Heb 13:15; cf. 1 Pet 25; Ps 116:13, 17; Mal 1:11), since it completes and surpasses all the sacrifices of the Old Covenant. The Holy and Divine Liturgy, because the Church's whole liturgy finds its center and most intense expression in the celebration of this sacrament; in the same sense we also call its celebration the Sacred Mysteries. We speak of the Most Blessed Sacrament because it is the Sacrament of sacraments. The Eucharistic species reserved in the tabernacle are designated by this same name.

Ps 115, 16 The heavens belong to the LORD

(Ps 115, 16) The heavens belong to the LORD

[16] The heavens belong to the LORD, but the earth is given to us.

(CCC 326) The Scriptural expression "heaven and earth" means all that exists, creation in its entirety. It also indicates the bond, deep within creation, that both unites heaven and earth and distinguishes the one from the other: "the earth" is the world of men, while "heaven" or "the heavens" can designate both the firmament and God's own "place" - "our Father in heaven" and consequently the "heaven" too which is eschatological glory. Finally, "heaven" refers to the saints and the "place" of the spiritual creatures, the angels, who surround God (Ps 115:16; 19:2; Mt 5:16).

Ps 115, 15 The LORD who made heaven and earth

(Ps 115, 15) The LORD who made heaven and earth

[15] May you be blessed by the LORD, who made heaven and earth.

(CCC 216) God's truth is his wisdom, which commands the whole created order and governs the world (Cf. Wis 13:1-9). God, who alone made heaven and earth, can alone impart true knowledge of every created thing in relation to himself (Cf. Ps 115:15; Wis 7:17-21). (CCC 287) The truth about creation is so important for all of human life that God in his tenderness wanted to reveal to his People everything that is salutary to know on the subject. Beyond the natural knowledge that every man can have of the Creator (Cf. Acts 17:24-29; Rom 1:19-20), God progressively revealed to Israel the mystery of creation. He who chose the patriarchs, who brought Israel out of Egypt, and who by choosing Israel created and formed it, this same God reveals himself as the One to whom belong all the peoples of the earth, and the whole earth itself; he is the One who alone "made heaven and earth" (Cf. Isa 43:1; Pss 115:15; 124:8; 134:3).

Ps 115, 4-5. 8 Their idols have mouths but do not speak

(Ps 115, 4-5. 8) Their idols have mouths but do not speak

[4] Their idols are silver and gold, the work of human hands. [5] They have mouths but do not speak, eyes but do not see. [8] Their makers shall be like them, all who trust in them.

(CCC 2112) The first commandment condemns polytheism. It requires man neither to believe in, nor to venerate, other divinities than the one true God. Scripture constantly recalls this rejection of "idols, (of) silver and gold, the work of men's hands. They have mouths, but do not speak; eyes, but do not see." These empty idols make their worshippers empty: "Those who make them are like them; so are all who trust in them" (Ps 115:4-5, 8; cf. Isa 44:9-20; Jer 10:1-16; Dan 14:1-30; Bar 6; Wis 13: 1- 15:19). God, however, is the "living God" (Josh 3:10; Ps 42:3; etc.) who gives life and intervenes in history.
