Just recently the priests of our church visited our new home, asking God to bless it. This is not just a Coptic custom, but an Orthodox one (and in fact, most religions include some sort of house blessing custom). As I intently listened to the prayers and read along as the service proceeded, I noticed a number of things that caught my attention. And I thought to myself, how does this compare with what the Eastern Orthodox do? Do they invoke the Holy Spirit? What do they declare as the purpose of this prayer? Do they pray over water even? Do they sprinkle water? Are the prayers themselves similar at all? I was fascinated with what I eventually found out.
