I would tend to agree with your statement “Science is not about opinion, nor is religion.” With this clarification…the tools of science, in general, are independent of opinion however the data gleaned from those tools are often and necessarily inculcated by myriad opinions as to their applicability, meaning, and accuracy. Science often stumbles along in what we may consider to be “progress” often despite the scientists performing the science - in the form of accident or beneficial coincidence. Paradigm shifts happen despite stubborn opinions to the contrary. Religion…well, just witness the state of the world. Religion is born in opinion, it breaths opinion ( this is a necessity of free will), and it breeds opinion, and the best one can hope for is to be led by God in some manner to having a true opinion.
What is science or religion divorced from those practicing it? Being fallen, finite and fallible human beings our opinions, even in the light of solid data, follow us like ubiquitous shadows sowing seeds of doubt despite having a true opinion and are forces of solidarity in our holding onto false opinion.
I am claiming that like all God given tools for our survival and advancement while living in his creation Satan can use those tools to further his own agendas. Isn’t it written in scripture that even he can quote from it for his own nefarious means?
IF the shroud cannot be definitely proven to be the actual burial shroud of the savior, reinforcing at least in some manner the Christian claims about Jesus’s life then we may have been better off if such a thing had not existed at all to debate over. Those who claim its inauthenticity will not be swayed otherwise in the absence of definitive proof of the accuracy of the claims made by those who believe in its authenticity. Satan can use the shroud vicariously to promote this shadow realm of doubt by using the solid existence of the shroud as a example of how the church promotes falsehood to further its own agendas despite evidence of its inauthenticity or lack of evidence of its authenticity. The shroud in essence serves no purpose in bridging this gap between the believer and the nonbeliever in order to further Gods will of saving everyone. It does however seemingly serve Satan’s will in sowing discord.
