What is Defilement?
Defilement is not on what you take in, it's about what you put out!
Defilement or All In
It concerns the worship God wants. The setting is controversial. The Pharisees come to Jesus with their perennial query: ‘Why do your disciples break the tradition of the elders? They don’t wash their hands before they eat!’ (15:1). In the way Jesus responds to them, two main things emerge, both highly significant not only for Jesus’ controversy with the Pharisees of his day, but also for Matthew’s controversy with the Pharisees of his.
The first point Jesus makes is this: God’s word, not human tradition, is the basis for authentic worship.
The second point Jesus made in this passage is that inner purity, not external ceremony, is what matters. The Pharisees, with their emphasis on ablutions, held the view that what entered into them could defile them (10–11).
The main point of controversy was this. The Pharisees had developed a whole ‘fence’ of traditions and additions to protect the law.
The dominant idea here is of the inconsistency which professes to aim to please God, but in fact opposes his will. Isaiah’s words (29:13) related originally to the people of his own day, but Jesus sees a correspondence (‘typology’) between their false religion and that of his own contemporaries which makes his words in effect a ‘prophecy’ about them too
Judaism had almost become a religion of ‘works’ designed to win the approval of God. And Jesus says, ‘Never!’
Judaism had not started out that way. It was a religion of sheer unmerited grace from God to Abraham. It flowed with love and trust and obedience.
And that is an attitude Jesus powerfully repudiates. ‘Works’ are a beggar’s refuge. For one thing, we could never keep every letter of the law day and night all our lives, and so we could never earn the coveted reward. Secondly, even if we could, the whole principle is sub-personal. One could do it all without a living relationship with God.
It does not consist merely in external things. Unclean foods could not defile people. They go into the stomach and pass out the other end. What defiles people is the stuff that comes from within: evil thoughts, murder, adultery, sexual immorality, theft, false testimony, slander (19). These are what defile people; but eating with unwashed hands does not defile people (20). The human heart is ‘deceitful above all things and beyond cure’. No palliatives will heal it.
Those two characteristics are what God is looking for in his worshippers. His word is not to be emasculated by human rules. And inner purity, not external rectitude, is what delights the heart of God.
