“How can Christians repair broken relationships caused by differences of opinion about COVID policies?”
I think it’s fair to say debates about vaccination, masking, distancing and lockdowns probably caused more dissension between believers than any single issue in my lifetime. In most cases interpretation of scripture had little or nothing to do with it; if the Bible was quoted at all, it was usually a verse or familiar Bible phrase tacked on as a gloss, like the “Vaccination is loving your neighbor” rhetoric.
