Heb 4, 7 He once more set a day, "today"

(Heb 4, 7) He once more set a day, "today"

[7] he once more set a day, "today," when long afterwards he spoke through David, as already quoted: "Oh, that today you would hear his voice: 'Harden not your hearts.'"

(CCC 2180) The precept of the Church specifies the law of the Lord more precisely: "On Sundays and other holy days of obligation the faithful are bound to participate in the Mass" (CIC, can. 1247). "The precept of participating in the Mass is satisfied by assistance at a Mass which is celebrated anywhere in a Catholic rite either on the holy day or on the evening of the preceding day" (CIC, can. 1248 § 1). (CCC 2179) "A parish is a definite community of the Christian faithful established on a stable basis within a particular church; the pastoral care of the parish is entrusted to a pastor as its own shepherd under the authority of the diocesan bishop" (CIC, can. 515 § 1). It is the place where all the faithful can be gathered together for the Sunday celebration of the Eucharist. The parish initiates the Christian people into the ordinary expression of the liturgical life: it gathers them together in this celebration; it teaches Christ's saving doctrine; it practices the charity of the Lord in good works and brotherly love: You cannot pray at home as at church, where there is a great multitude, where exclamations are cried out to God as from one great heart, and where there is something more: the union of minds, the accord of souls, the bond of charity, the prayers of the priests (St. John Chrysostom, De incomprehensibili 3, 6: PG 48, 725). (CCC 2181) The Sunday Eucharist is the foundation and confirmation of all Christian practice. For this reason the faithful are obliged to participate in the Eucharist on days of obligation, unless excused for a serious reason (for example, illness, the care of infants) or dispensed by their own pastor (Cf. CIC, can. 1245). Those who deliberately fail in this obligation commit a grave sin. (CCC 2182) Participation in the communal celebration of the Sunday Eucharist is a testimony of belonging and of being faithful to Christ and to his Church. The faithful give witness by this to their communion in faith and charity. Together they testify to God's holiness and their hope of salvation. They strengthen one another under the guidance of the Holy Spirit.
