Dear friend
If an Ordained Priest Blesses your house, it is the OFFICE of the Priest that is Holy. All Priests in this manner are Holy as they are a Priest in Christ Jesus. There is only ONE Priest and that is Christ Jesus, all other Priests in Apostolic Succession are ordained in His Holy Order.
If you were to sprinkle Holy Water in your house in the Name of the Father and the Son and the Holy Spirit, this is a blessing upon it, but it is not the same as a Priests blessing, just the same I say at the end of my posts, ‘God Bless you and much love and peace to you and those you love’ it is a prayer of blessing to you and those you love, but it is not the same as a Priests blessing which is in the Holy Order of Jesus Christs’ Priesthood.
I think this is what John Russell Jr was referring to, not the holier the Priest as some are indeed more holy than others, but the Holiness of Christ Jesus is blessed and bestowedd upon you and your house by the authority of God the Father and by the power of the Holy spirit and His Holy Catholic and Apolostolic church. Just as a Priest can have sinned but that does not affect His OFFICE to consecrate the Host at Holy Mass, the Priests office is pure and cannot be affected by the actions of the Priest etc, even if the Priest should not even believe the consecration takes place, it does because the office of the Priest is infallible, though for example he may be a murderer (extreme example but you see what I mean)
God bless you and much love and peace to you and those you love
