(Heb 9, 13-14) Christ offered himself unblemished to God

[13] For if the blood of goats and bulls and the sprinkling of a heifer's ashes can sanctify those who are defiled so that their flesh is cleansed, [14] how much more will the blood of Christ, who through the eternal spirit offered himself unblemished to God, cleanse our consciences from dead works to worship the living God.

(CCC 1127) Celebrated worthily in faith, the sacraments confer the grace that they signify (Cf. Council of Trent (1547): DS 1605; DS 1606.). They are efficacious because in them Christ himself is at work: it is he who baptizes, he who acts in his sacraments in order to communicate the grace that each sacrament signifies. The Father always hears the prayer of his Son's Church which, in the epiclesis of each sacrament, expresses her faith in the power of the Spirit. As fire transforms into itself everything it touches, so the Holy Spirit transforms into the divine life whatever is subjected to his power. (CCC 1128) This is the meaning of the Church's affirmation (Cf. Council of Trent (1547): DS 1608) that the sacraments act ex opere operato (literally: "by the very fact of the action's being performed"), i.e., by virtue of the saving work of Christ, accomplished once for all. It follows that "the sacrament is not wrought by the righteousness of either the celebrant or the recipient, but by the power of God" (St. Thomas Aquinas, STh III, 68, 8). From the moment that a sacrament is celebrated in accordance with the intention of the Church, the power of Christ and his Spirit acts in and through it, independently of the personal holiness of the minister. Nevertheless, the fruits of the sacraments also depend on the disposition of the one who receives them. (CCC 1131) The sacraments are efficacious signs of grace, instituted by Christ and entrusted to the Church, by which divine life is dispensed to us. The visible rites by which the sacraments are celebrated signify and make present the graces proper to each sacrament. They bear fruit in those who receive them with the required dispositions. (CCC 1132) The Church celebrates the sacraments as a priestly community structured by the baptismal priesthood and the priesthood of ordained ministers. (CCC 1133) The Holy Spirit prepares the faithful for the sacraments by the Word of God and the faith which welcomes that word in well-disposed hearts. Thus the sacraments strengthen faith and express it. (CCC 1134) The fruit of sacramental life is both personal and ecclesial. For every one of the faithful an the one hand, this fruit is life for God in Christ Jesus; for the Church, on the other, it is an increase in charity and in her mission of witness.
