Heb 10, 1-4 Law has only a shadow of the good things

Hebrews 10

(Heb 10, 1-4) Law has only a shadow of the good things

[1] Since the law has only a shadow of the good things to come, and not the very image of them, it can never make perfect those who come to worship by the same sacrifices that they offer continually each year. [2] Otherwise, would not the sacrifices have ceased to be offered, since the worshipers, once cleansed, would no longer have had any consciousness of sins? [3] But in those sacrifices there is only a yearly remembrance of sins, [4] for it is impossible that the blood of bulls and goats take away sins.

(CCC 128) The Church, as early as apostolic times (Cf. 1 Cor 10:6, 11; Heb 10:1; l Pt 3:21), and then constantly in her Tradition, has illuminated the unity of the divine plan in the two Testaments through typology, which discerns in God's works of the Old Covenant prefigurations of what he accomplished in the fullness of time in the person of his incarnate Son. (CCC 1540) Instituted to proclaim the Word of God and to restore communion with God by sacrifices and prayer (Cf. Mal 2:7-9), this priesthood nevertheless remains powerless to bring about salvation, needing to repeat its sacrifices ceaselessly and being unable to achieve a definitive sanctification, which only the sacrifice of Christ would accomplish (Cf. Heb 5:3; 7:27; 10:1-4). (CCC 1202) The diverse liturgical traditions have arisen by very reason of the Church's mission. Churches of the same geographical and cultural area came to celebrate the mystery of Christ through particular expressions characterized by the culture: in the tradition of the "deposit of faith" (2 Tim 1:14 (Vulg.) in liturgical symbolism, in the organization of fraternal communion, in the theological understanding of the mysteries, and in various forms of holiness. Through the liturgical life of a local church, Christ, the light and salvation of all peoples, is made manifest to the particular people and culture to which that Church is sent and in which she is rooted. The Church is catholic, capable of integrating into her unity, while purifying them, all the authentic riches of cultures (Cf. LG 23; UR 4). (CCC 1205) "In the liturgy, above all that of the sacraments, there is an immutable part, a part that is divinely instituted and of which the Church is the guardian, and parts that can be changed, which the Church has the power and on occasion also the duty to adapt to the cultures of recently evangelized peoples" (John Paul II, Vicesimus quintus annus, 16; cf. SC 21).
