When Constantine's mum went to Palestine and found relics and bits of the Cross by the bucketload, there was nothing to substantiate her 'claim'. Even the Church of the Holy Sepulchre is built on little more than speculation. There is no verifiable evidence that links the tomb with that of the Resurrection. After all, two centuries and more had passed where Jerusalem was little more than a ruin, and the Church based itself at Antioch and Ephasus, rather than the devastated city. Believers were more concerned with sharing their faith and preserving their lives, than guarding spurious sites.
