In liturgical tradition this is one of the terms to distinguish the intercessory prayers offered during the Eucharist celebration.
These intercessory prayers are also referred as the Prayer of the Faithful or the Universal Prayer.
Typically, these prayers are in the litany form of petitions offered by the deacon (or another in his absence) with a sung or spoken response, such as, “Lord, hear our prayer.”
The petitions are introduced by an invitation to pray by the presider, and is completed with a concluding prayer.
In general, the intentions in order are for the needs of the whole Church, for public authorities and the salvation of the world, for those who are oppressed, and for the local community including the sick and deceased. (8:33)
