During the liturgical year, the Church celebrates the role played by the Holy Angels, in the events of salvation(282) and commemorates them on specific days: 29 September (feast of the Archangels Michael, Gabriel and Raphael), 2 October (the Guardian Angels). The Church has a votive Mass dedicated to the Holy Angels whose preface proclaims that “the glory of God is reflected in his Angels”(283). In the celebration of the sacred mysteries, the Church associates herself with the angelic hymn and proclaims the thrice holy God (cf. Isaiah 6, 3)(284) invoking their assistance so that the Eucharistic sacrifice “may be taken [to your] altar in heaven, in the presence of …] divine majesty”(285). The office of lauds is celebrated in their presence (cf. Ps 137, 1)(286). The Church entrusts to the ministry of the Holy Angels (cf. Aps 5, 8; 8, 3) the prayers of the faithful, the contrition of penitents(287), and the protection of the innocent from the assaults of the Malign One(288). The Church implores God to send his Angels at the end of the day to protect the faithful as they sleep(289), prays that the celestial spirits come to the assistance of the faithful in their last agony(290), and in the rite of obsequies, invokes God to send his Angels to accompany the souls of just into paradise(291) and to watch over their graves.
