This is the name given to words of St Paul often used -normally by the worship leader but sometimes by the congregation addressing one-another -to conclude a time of worship.
The grace of our Lord Jesus Christ,
and the love of God
and the fellowship of the Holy Spirit,
be with us* all, evermore. Amen.
* Paul actually wrote "with you all" ( 2 Corinthians 13:14) and this form may be used when spoken by the worship leader.
