Heb 9, 6-7 The high priest offers for himself

(Heb 9, 6-7) The high priest offers for himself

[6] With these arrangements for worship, the priests, in performing their service, go into the outer tabernacle repeatedly, [7] but the high priest alone goes into the inner one once a year, not without blood that he offers for himself and for the sins of the people.

(CCC 1546) Christ, high priest and unique mediator, has made of the Church "a kingdom, priests for his God and Father" (Rev 1:6; cf. Rev 5:9-10; 1 Pet 2:5, 9). The whole community of believers is, as such, priestly. The faithful exercise their baptismal priesthood through their participation, each according to his own vocation, in Christ's mission as priest, prophet, and king. Through the sacraments of Baptism and Confirmation the faithful are "consecrated to be… a holy priesthood" (LG 10 § 1). (CCC 1123) "The purpose of the sacraments is to sanctify men, to build up the Body of Christ and, finally, to give worship to God. Because they are signs they also instruct. They not only presuppose faith, but by words and objects they also nourish, strengthen, and express it. That is why they are called 'sacraments of faith"' (SC 59). (CCC 1121) The three sacraments of Baptism, Confirmation, and Holy Orders confer, in addition to grace, a sacramental character or "seal" by which the Christian shares in Christ's priesthood and is made a member of the Church according to different states and functions. This configuration to Christ and to the Church, brought about by the Spirit, is indelible (Cf. Council of Trent (1547): DS 1609), it remains for ever in the Christian as a positive disposition for grace, a promise and guarantee of divine protection, and as a vocation to divine worship and to the service of the Church. Therefore these sacraments can never be repeated. (CCC 1125) For this reason no sacramental rite may be modified or manipulated at the will of the minister or the community. Even the supreme authority in the Church may not change the liturgy arbitrarily, but only in the obedience of faith and with religious respect for the mystery of the liturgy. (CCC 1126) Likewise, since the sacraments express and develop the communion of faith in the Church, the lex orandi is one of the essential criteria of the dialogue that seeks to restore the unity of Christians (Cf. UR 2; 15).
