Interesting information. I was just going by what I have been taught over the years ... that a sacramental should be treated with respect and that wearing a rosary was not following those guidelines.
The St. Christopher medal? Not a sacramental ... merely a medal.
Regarding St. Christopher medals - I had always been taught that sacramentals are objects or actions set apart to bring us closer to God. I believe St. Christopher medals meet that criteria. I could very well be mistaken, although I was curious so I did a little digging - this and this seem to agree with me. Thoughts?
