Believers are, for the most part, quite equitable about whether or not the Shroud of Turin is the burial shroud of Christ.
Atheists, on the other hand, tend to get worked up about it. They seem almost to fear it. I am guessing that this is because they’ve got so much ego invested in their non-belief that the thought that some artifact might rattle that a bit is scary to them.
The first time I ever heard of the Shroud was when I came across a book written by a member of the scientific team which investigated it in 1978. This group is often referred to as STURP Team. The acronym stands for Shroud of Turin Research Project.
The video below is a brief reflection by one of the team members on how the investigation and its findings affected him.
