A person does not need physical objects to obtain or maintain their Christianity. But the God of today is the same as the God of the Israelites. He is the Pillar of Fire in the dessert. When the king of Babylon used the plates from God's temple for a feast God wrote his doom on a wall and took from him his empire. When the Ark of the Covenant was captured and placed before an idol the idol fell on it's face before the ark. Objects can be sacred. They are not vital for salvation. They should not be prayed to. When Jesus dies the curtain was torn asunder. There is no priesthood or barrier that separates us from the Holy of Holy. But God has not changed. An object touched by Jesus would surely be an article of faith. Until disproved it should in the least make men wonder, and remind them victory over death was won if not inside that specific shroud at least one like it.
Bravo.
