105. Where there is the custom of blessing houses in celebration of the Resurrection, this blessing is to be imparted after the Solemnity of Easter, and not before, by the parish priest, or other priests or deacons delegated by him. This is an opportunity for exercising a pastoral ministry. (SRC, Decr. Maxima redemptionis nostrae mysteria (16 Nov. 1955), n.. 21, AAS 47 (1955), 847) The parish priest should go to each house for the purpose of undertaking a pastoral visitation of each family. There he will speak with the residents, spend a few moments with them in prayer, using texts to be found in the book (of Blessings) (Book of Blessings, caput I, II, Ordo benedictionis annuae familiarum in propriis domibus) In larger cities consideration should be given to the gathering of several families for a common celebration of the blessing for all.
Easter blessing of homes should take place during the Easter season, and not in anticipation of it: that seems logical. Some US parishes have thousands of households, so this could be a significant ministry of outreach. Where do you suppose the priority would lie: with regular parishioners or those in the fringes?
And for those larger parishes, that recommendation of a gathering of families: it seems rather timely, eh? Perhaps that is the ideal for solid parishioners, to invite them to the parish for a celebration.
