The tradition of sanctifying houses and many things dates back to ancient times. Many believers observe it to this day. However, this ritual has its own nuances.
The consecration of things and housing is an ordinary and natural thing for the Orthodox. However, it should immediately be noted that this is not the acquisition of a kind of "insurance" through prayers, as many believe. This is just a request to God to bless the use of new things for the benefit of people. Here we are talking more about spiritual benefits than material ones. Consecration of something means the reading of special prayers and the sprinkling of holy water. Each believer can do this ritual independently. For the sanctification of things there is a prayer "For the sanctification of every thing." It can be found in the prayer book. Its virtual version is here http://www.molitvoslov.com/text533.htm After reading it, you should sprinkle the thing with holy water. For the consecration of the car and the apartment there are special brief rites of prayers. They are in the liturgical book - a treasury. Some believers consecrate their homes and cars on their own. There is nothing sinful in this. To consecrate the apartment, you can pick up a bowl of holy water, a burning church candle and, if any, a censer with incense. Reading a prayer, you should go around all the rooms of the house and sprinkle the corners of holy water. However, consecration of a house by a priest is a completely different matter. In order to properly consecrate the apartment, you should come to any church and invite the priest home at a time convenient for him and you. Let this not be an ordinary affair, but a solemn event in the life of your family. Best of all, if all its members will be present at the consecration of the house. To consecrate the machine, you should come to the church on it and turn to the priest.
