What is an embolism in the Catholic liturgy?

In the Catholic liturgy, an embolism is a prayer that follows the Our Father during the Mass, specifically in the context of the Eucharistic Prayer. It is a supplication that asks for deliverance from various forms of evil and seeks God's mercy and peace for the faithful. This prayer emphasizes the Church's communal nature and its reliance on God's grace for salvation and protection. The embolism traditionally begins with the phrase "Deliver us, Lord, we pray..." and is an integral part of the liturgical celebration.
