What would Knox have thought?

What John Knox thought of Anglican liturgy was no secret. Anything added by human invention in worship was idolatry. Why was he so unyielding about worship? Because any and all idols suplant Jesus Christ. We may be too sophisticated for ones hewn from blocks of wood or stone, but ours may be all the more tenacious for their subtlety. We can get very creative when sacrificing straight-up Gospel on the altar of transcendence. 

St. Martins, oldest continuous church in Britain, dating from Roman and Anglo-Saxon times.
