I can't speak for annsni, but I will try.
I think she means people who are obsessed with the shroud as a holy relic and they consider this "proof" of what they believe and their faith.
The Bible says that faith is the evidence of things NOT seen.
It's kind of like those who have hunted for Noah's Ark (which in my opinion is rotted away to nothingness) - what would have happened if they put all of that time and energy into growing in Christ and reaching the lost?
God doesn't want people to have faith in His Son based on a relic or icon.
This obsession that some have with the shroud (not anyone on the BB, but people in general) is like the obsession that some people in Rome who to this very day climb the steps of the Scala Santa on their hands and knees and kiss the painting at the top and believe that their sins are forgiven.
Religious relics and icons from all religions of all the world come to embody the believer's faith - and it's very, very sad.
Exactly. God provided proof to the early disciples so that they could then testify to us. Their testimony, in accordance with the old testament scriptures, and the facts we know of the cost of preaching a resurrected Jesus to the apostles is more than enough to convince us of the reality of the resurrection of Jesus Christ from the dead. Paul, when proving the resurrection of Jesus to the Corinthians referring to three things - the gospel he had preached to them which first taught the death, burial, and resurrection of Jesus, the old testament scriptures, and the more than 500 witnesses. Why would he omit the shroud if it was real? It seems like convincing evidence to me, if true.
God has left us precious few physical evidences of the things in scripture. The ark is who knows where. Nearly no reference to the Israelites in Egypt. Very few corroborations for scriptural events from outside sources. Why is this? I say it's because we aren't to believe the bible because of physical evidence, but rather because of faith. Consider the existence of Belshazzar. For years secular historians used lack of secular evidence of him to blast the bible. Well, turns out they found a cylinder his father wrote and he is named on it. We didn't need that evidence to believe the bible, for years believers has known Belshazzar existed because they had faith in God to accurately inspire His word. Now people doubt Darius the Median existed. I don't. Who was he? People have their theories. It really doesn't matter. The bible says he existed, and we are to believe it. Physical evidence is not needed for belief, only faith.
