These are the things which defile a man: but to eat with unwashed hands defiles not a man.
All Commentaries on Matthew 15:20 Go To Matthew 15
Remigius of Rheims
AD 533
The Lord was used to speak in parables, so that Peter when he heard, “That which entereth into the mouth, defileth not a man,” thought it was spoken as aparable, and asked, as it follows; “Then answered Peter, and said unto him, Declare unto us this parable.” And because he asked this on behalf of the rest, they are all included in the rebuke, “But he said, Are ye also yet without understanding?”.
Having named the vices which are forbidden by the divine Law, the Lord beautifully adds, “These are they that defile a man,” that is, make him unclean and impure.
