All knowing begins with what Michael Polanyi calls a “fiduciary framework.” (fiduciary = pertaining to fides, “involving trust”): an interpretive framework that one takes initially on faith until it proves itself by yielding a harvest of understanding…If Polanyi is right, Christian theology is no worse of than modern science. Everyone has to have faith in something to get the knowing process started…A good case could be made for making Scripture the Christians’ default fiduciary framework, the source and norm of theological knowledge and wisdom.
