This is what is said during the sign of peace:
Sign of Peace:It's a lovely thing, really. I know I can get crabby and impatient around people, especially in crowded places. I always try to make an effort to really remind myself to offer a heartfelt "Peace be with you!" to those around me, especially when I've been feeling irritated or grouchy!
Priest: Lord Jesus Christ, you said to your apostles: I leave you peace, my peace I give you. Look not on our sins, but on the faith of your Church, and grant us the peace and unity of your kingdom where you live for ever and ever.
Priest: The Peace of the Lord be with you always.
All: And also with you.
Deacon or Priest: Let us offer each other a sign of peace.
[The ministers and all the people exchange an embrace, handshake, or other appropriate gesture of peace with those near them, according to local custom.]
Therefore, if you bring your gift to the altar, and there recall that your brother has anything against you, leave your gift there at the altar, go first and be reconciled with your brother, and then come and offer your gift. (Matt 5:23-4)
