The revised Roman Ritual establishes rites and norms for Holy Communion and Eucharistic worship outside Mass, presenting the Mass as the source and goal of all Eucharistic devotion. It regulates reservation in tabernacles and chapels, chiefly for Viaticum and Communion of the sick and elderly, while also providing for adoration of Christ’s real presence. Norms address the state of grace, confession after mortal sin, the one-hour fast, thanksgiving, host renewal, episcopal adaptations, and approved translations.

Full and abbreviated rites for Communion include Scripture, the Lord’s Prayer, the sign of peace, distribution, prayer, blessing, and dismissal; special forms serve the sick, hospitals, and the dying, who may renew their baptismal profession of faith. Exposition requires Scripture, song, prayer, and silence; priests or deacons give Benediction, while acolytes or lay ministers may expose and repose the Sacrament when necessary. Regulations for processions and Eucharistic congresses connect public Eucharistic faith with catechesis, charity, and social outreach. Biblical readings, hymns, antiphons, responsories, and prayers—including Tantum Ergo, Lauda Sion, Adoro te devote, and Ubi caritas—complete the rites, with formularies seeking unity, charity, service, perseverance toward eternal life, and hope of future glory.
