I have a few cross necklaces. A small gold one was my mother's and I wear it very occasionally to feel close to her.
Another was chosen by me and purchased for me by my children for Mother's Day (which is another thing I do now that was unthinkable as a JW). It's a Gregorian cross (equal crosspieces) with a different semi-precious gemstone for each piece and the center, with some diamond chips for fillers. I really love it!
Most recently, my best friend from high school, sent me a silver/marcasite cross, fairly large and ornate, with a card that told me she knew I had been getting through my cancer struggle so well in large part because of my faith. And while I DO have faith in a Higher Power, I am not a member of any organized religion at present. I feel fine wearing a cross because I have great respect for many of Jesus' teachings, and I've felt a close connection with Him partly because I was born on Dec. 25.
I have no crucifixes hanging in my home.
And, for the record, I feel I've gotten through my cancer struggle so well in large part because of my JWD family holding me near in thoughts and prayers, as well as the Reiki treatments, medical treatments, and the support of loving friends like her!
