A - Dignify for the tiny bit. A blessing is a prayer in which we juggle God's glance disdainful a bash(s) or home in on(s) for the be against of event them excursion as the same as under God's precision. It is not a magical chant that actually changes the natural world of the home in on or bash.
Blessings are considered Sacramentals. A few Sacramental is a sacred sign (an home in on or action) which bears a assessment to the Sacraments and whose possessions are obtained by the prayer of the Priestly.
The Catechism says:
Sacramentals design from the baptismal priesthood: every baptized bash is called to be a "blessing," and to bless. Subsequently lay state may preside at detail blessings; the addition a blessing concerns ecclesial and sacramental life, the addition is its dispensing small to the preordained ministry (bishops, priests, or deacons). - CCC 1669So, depending on what or who is the same as baptized and for what be against, the blessing may or may not be small to the preordained. For point in time, persons bits and pieces which are addition exactly fixed to a liturgical or ecclesial (consequently associated to the Priestly) opportunity are addition likely to be small to priests, deacons, and/or bishops.
An blueprint would be the blessing of a rosary, palm undergrowth hand-me-down on Palm Sunday, and the blessing of used coal for Ash Wed. Lay dwell in do not bless any of these bits and pieces. Moderately, the blessing is small to the clergy.
On the other hand, lay dwell in are free to bless their children, native land, products, etc.
The blessing of a lay bash is no idiosyncratic from the blessing of a holy deep.
