on Holy Saturday and during Eastertime
1. The parish priest (or a priest who has his permission), vested in surplice and white stole, visits the homes of his parishioners on Holy Saturday or another day during Eastertime, in order to bless the homes and their occupants with the Easter water. He should be assisted by a server who carries a vessel containing blessed water taken from the baptismal font before the holy oils were added. As he enters the home he says:
P: God’s peace be in this home.
All: And in all who live here.
2. Then he sprinkles the dwelling’s main room and the occupants, saying the antiphon:
I saw water flowing out from beneath the threshold of the temple, alleluia; and all to whom this water came were saved, and they shall say, alleluia, alleluia. (Ps. 117.) Give thanks to the Lord, for He is good, for His mercy endures forever. V. Glory be to the Father, and to the Son, and to the Holy Spirit. As it was in the beginning, is now, and ever shall be, world without end. Amen. I saw water flowing out from beneath the threshold of the temple, alleluia; and all to whom this water came were saved, and they shall say, alleluia, alleluia.
Next he says:
P: Lord, show us your mercy, alleluia.
All: And grant us your salvation, alleluia.
P: Lord, heed my prayer.
All: And let my cry be heard by you.
P: The Lord be with you.
All: May He also be with you.
Let us pray.
Hear us, holy Lord and Father, almighty everlasting God; and as you guarded the homes of the Israelites from the avenging angel on their flight from Egypt, if their homes were signed with the blood of a lamb–therein prefiguring our Easter sacrifice in which Christ is the victim–so likewise in your goodness send your holy angel to watch over and protect all who live in this home, to be with them and give them comfort and encouragement; through Christ our Lord.
3. The rite described above is used also when the blessing of homes is carried out on another day in Eastertime, in accord with local custom.
