 In Christianity, house blessing is an ancient tradition, that can be found in Roman Catholicism, Orthodox Christianity, and some branches of Protestantism.In Roman Catholicism, Lutheranism, Anglicanism, Methodism and Orthodoxy, they are usually performed by a pastor who may sprinkle holy water (depending on denominational tradition) as he walks through every room of the house, accompanied by the occupants of the house, whilst praying for the occupants.House blessings date back to the early days of Christianity, and in Catholicism, the rite takes the form of a prayer, with intercessions and several benedictions.
