Extended Vigil of the Office of Readings is the optional enlargement of the Roman Office of Readings for Sundays, solemnities, and feasts by adding vigil canticles, a Gospel, and the prescribed conclusion before the Te Deum.
The Office retains a vigil character
Laudis canticum made the Office of Readings suitable for any hour while preserving its character as a night office for those who celebrate it as a vigil. The General Instruction commends night prayer and permits communities or individuals to extend the Office on Sundays, solemnities, and feasts in continuity with the Church's tradition of keeping watch.[1]
The extension is part of the Liturgy of the Hours, not an independent devotion called a vigil. It begins with the Office of Readings celebrated according to its calendar day and adds the elements specified in the liturgical book. Moving the ordinary Office to nighttime without those additions preserves vigil character but is not the technical extended form.[2]
Structure after the second reading
After the two readings and their responsories, and before the Te Deum, three canticles are inserted from the appendix. A Gospel is then proclaimed, with or without a homily as circumstances warrant, followed by the hymn Te Deum. The prayer of the day concludes the Office in the usual way.
The Gospel is exceptional because the Office of Readings normally contains no Gospel pericope; the Mass lectionary carries the Church's annual proclamation of the Gospels. The extended vigil's reading is selected from the approved appendix or proper liturgical provision, not improvised as a third long reading from any preferred text.
Canticles and Gospel
The added canticles create a scriptural vigil sequence and are followed by the Gospel as the high point of the extension. Their placement is fixed. Inserting them before the patristic reading or after the Te Deum obscures the form authorized by GILH 73 and should not be presented as the official extended vigil.
Possible homily
A homily may follow the Gospel, especially in communal celebration, but the permission does not turn the Office into Mass or create a second Liturgy of the Word. No Eucharistic Prayer, offertory, or distribution of Communion belongs to this Hour merely because a Gospel and homily are present.
Relation to other vigils
The extended Office differs from the Easter Vigil, which is the Paschal Triduum's unique liturgy with its own service of light, readings, baptismal liturgy, and Eucharist. It also differs from a proper Vigil Mass, an anticipated Sunday Mass, a devotional watch, and the historical office of Matins in other forms of the Roman Rite.
Communal singing, silence, and a true nighttime schedule can deepen the sign of watchfulness, but validity does not depend on maximal duration or dramatic darkness. The approved structure serves expectant prayer. A short ordinary Office remains fully the Church's liturgy and is not deficient because the optional extension is not used.
