I read the article. There’s nothing beyond speculation that this reliquary and bones came from Jerusalem. In fact, speculation is all we can engage in at this far-removed date, there not being sufficient evidence to go on.
In any event. Even if it were the bone of John the Baptist, it’s nothing to worship. We worship God and His son Jesus Christ. Any other worship is idolatry. It shouldn’t even be revered. Held in respect perhaps as we do our ancestors, honored for what it is, but not revered, and certainly not worshiped.
