Q: I asked my best friend who is catholic and she didnt know.
A: Then taking the five loaves and the two fish, and looking up to heaven, he said the blessing over them, broke them, and gave them to the disciples to set before the crowd. (Luke 9:16) Sacramentals are sacred signs that help us live holy lives although they do not produce sanctifying grace. Sacramentals include blessings of persons, meals, objects (including water), and places. The priest blesses the congregation during Mass. Christians bless their meals. "Bless us O Lord and these thy gifts, ..." Priests bless water, animals, ships, homes, and even automobiles. "God bless this home and all those who enter here."
