Someone once told me that when his house was blessed the priest went through every room. When I was present at the blessing of my father's house, the (SSPX) priest only blessed a central area. I'm trying to figure out why, without asking him, since I'm not sure he'd give me an honest answer.
He knew that my father gave permission for the blessing, but that he didn't want anything to do with it, and didn't even want to meet the priest. I'm wondering if the priest needs clear permission from the head of the household before he feels he can go through every room when he blesses a house.
