Invitatory

The invitatory (lat. invitation) opened the liturgy of the hours of a day.

It consists of the vesicles

V / Domine, labia mea Aperies. R / Et os meum annuntiábit Laudem tuam. V / Lord, open my lips. R / order my mouth proclaim your praise.

And the responsorisch recited Psalm 95 ( exultemus Venite Come, let us rejoice before the Lord and joyful noise to the rock of our salvation ). In the Liturgy of the Hours of the Roman Catholic Church this psalm can be replaced by other Psalms ( Ps 24, Ps 67 or Ps 100) .. For a invitatory depending on hard or time changing in the church year antiphon is part of the Psalm, each in the bid Venite adoremus / Come, let us adore him opens. At Christmas, for example, the antiphon is to invitatory:

Natus est nobis Christ: Venite, Adoremus. Christ is born for us: Come, let us adore him!

The invitatory is as always opening before the first prayer of the day, the ( Office of Readings or Matins and Lauds or Vigil ). The Psalm of Invitatoriums with its antiphon may " depending on the circumstances " be omitted if it precedes Lauds.
