I know that only a true blessing can be given by an ordained Catholic priest, to both people and religious articles.
But I have heard in a few instances of the possibility of other people giving sort of “blessings.” When I was a child my mother, a good Catholic, used to give me a blessing before going to bed. She called it a motherly blessing. She simply made a cross on my forehead and sent me to bed.
Secondly, I was wondering about the blessing an ordained Catholic deacon can give. I know that they definitely can give real blessings and blessings to religious articles and water, etc., as my father is a deacon. But would this blessing be less than a blessing of an ordained priest, and if a deaon blesses a religious article, would the article then become a sacramental?
