And he said,
Draw not near here: put off your shoes from your feet, for the place on which you stand is holy ground.
All Commentaries on Exodus 3:5 Go To Exodus 3
Augustine of Hippo
AD 430
What are the shoes? Well, what are the shoes we wear? Leather from dead animals. The hides of dead animals are what we protect our feet with. So what are we being ordered to do? To give up dead works. This is symbolically what he instructs Moses to do in his honor, when the Lord says to him, “Take off your shoes. For the place you are standing in is holy ground.” There’s no holier ground than the church of God, is there? So as we stand in it let us take off our shoes, let us give up dead works.
