I will be honest, the notion of Relic is an aspect of Catholicism that I find very difficult to understand.
What good can a piece of bone or a bloodstained cloth be, even if it came from Jesus Christ Himself? Can it lead me to live a more moral life, or give me a more thorough understanding or the Faith, or forgive my sins?
“What good can a piece of bone or a bloodstained cloth be, even if it came from Jesus Christ Himself”?
- Tell that to the woman afflicted with a hemorrhage for twelve years in Luke 8. She did not even meet Jesus before she merely touched a tassel on His cloak. Immediately the bleeding stopped. The same miracle is recounted in Mark 5 - the woman, according to Mark, said “If I but touch His clothes, I shall be cured”.
Indeed, Christ’s response to the woman was that her faith had saved her - it wasn’t merely a simple act of touching His cloak. She needed faith.
Relics of saints work in the same way. They are not to be treated as lucky charms. However, the can be valuable pointers for the faithful as they journey through life - they can aid prayer, or help a person to more closely imitate a particular saint, or unite themselves closely in difficult times with a saint who also suffered. The veneration of relics can be most meritorious.
God gave us the Bible, the Church, the Sacraments, and His Son. How can that not be enough already?
What the Church teaches is most certainly enough. No one is obliged to own relics, or to have a devotion to a particular saint. You could say the same about many Catholic practices - the Rosary, the Stations of the Cross, etc. - these are “optional” devotions which some people feel particularly drawn to. However, as I said, they are “pointers” or “signposts” to God - you could say they give some people a spiritual boost. But if you stay close to the Church’s teachings (which actually encourage veneration of sacred images and relics) then you may be sure that you are already on the right path!
However, it is worth reiterating, that one should be very wary when looking for relics, especially over the internet. Personal ownership of first-class relics is strongly discouraged, and hence the proper channel to go through is to apply to the Reliquarium in Rome - I would suggest this course of action for the O.P… As stated earlier, it is absolutely forbidden to sell relics (Can. 1190 #1).
