Well, Jesus Christ is the cornerstone of our faith, thank goodness. I think that all of the variations of the faith have added valuable things to the building of it (some more than others). But there were many things added by many traditions that should not be there, and this practice will no doubt continue.
For my own personal faith, most of the building was done by and in the Evangelical church. And one of the key foundational stones loosened, crumbled a little, and then was violently dislodged. Much of the building came tumbling down. What survived was later knocked down by me as I struggled to figure out what was true about my faith and what wasn’t.
Haven’t spent rather a long time amidst the rubble, begging God to rebuild (or at least show mercy to me if it couldn’t be rebuilt), I finally found the Cornerstone buried under the mess. And I was able to make out the line of foundational stones. And now begins the hard labour of fitting together the stones that should be there, of destroying the stones that shouldn’t, and—most challenging—determining which is which.
Thank God for Biblical scholars.
Though I suppose it’s the presence of Biblical scholars that enables me to do all of this questioning. ;)
