A brief but important description of those physical manifestations of ritual that never made it into the “S”acraments:
Holy Mother Church has, moreover, instituted sacramentals. These are sacred signs which bear a resemblance to the sacraments: they signify effects, particularly of a spiritual kind, which are obtained through the Church’s intercession. By them (people) are disposed to receive the chief effect of the sacraments, and various occasions in life are rendered holy.
So they are also a medium of God’s grace. They also point their recipients to the direction of holiness.
