The opposition against Jesus escalates when the Pharisees and scribes criticize Jesus’ disciples for not washing their hands. Although the man-made traditions surrounding God’s Law may have had good intentions, Jesus rebukes these men who have let their traditions replace God’s Word. To the entire crowd, Jesus teaches that true uncleanness comes not from without but from within. Jesus patiently teaches His disciples the same reality concerning the true defilement of man. People are not sinners because they sin. People sin because they are sinners. Therefore, only the Gospel of Jesus Christ can bring salvation to us.

Rev. Brian Flamme, pastor at Immanuel Lutheran Church and School in Roswell, NM, joins host Rev. Timothy Appel to study Matthew 15:1-20.

“The Reign of Heaven Stands Near” is a series on Sharper Iron that studies the Gospel according to St. Matthew. The first evangelist proclaims that God has fulfilled His Old Testament promises by sending Jesus to bring the reign of the heavens among us. As the Son of David, Jesus is the gracious King we need, and as the Son of Abraham, Jesus is the blessing to all the families of the earth.

Sharper Iron, hosted by Rev. Timothy Appel, looks at the text of Holy Scripture both in its broad context and its narrow detail, all for the sake of proclaiming Christ crucified and risen for sinners. Two pastors engage with God’s Word to sharpen not only their own faith and knowledge, but the faith and knowledge of all who listen. Pastor Appel serves at Faith Lutheran Church in Godfrey, IL.

Matthew 15:1-20

Traditions and Commandments

[1] Then Pharisees and scribes came to Jesus from Jerusalem and said, [2] “Why do your disciples break the tradition of the elders? For they do not wash their hands when they eat.” [3] He answered them, “And why do you break the commandment of God for the sake of your tradition? [4] For God commanded, ‘Honor your father and your mother,’ and, ‘Whoever reviles father or mother must surely die.’ [5] But you say, ‘If anyone tells his father or his mother, “What you would have gained from me is given to God,” [6] he need not honor his father.’ So for the sake of your tradition you have made void the word of God. [7] You hypocrites! Well did Isaiah prophesy of you, when he said:

[8] “‘This people honors me with their lips,

but their heart is far from me;

[9] in vain do they worship me,

teaching as doctrines the commandments of men.’”

What Defiles a Person

[10] And he called the people to him and said to them, “Hear and understand: [11] it is not what goes into the mouth that defiles a person, but what comes out of the mouth; this defiles a person.” [12] Then the disciples came and said to him, “Do you know that the Pharisees were offended when they heard this saying?” [13] He answered, “Every plant that my heavenly Father has not planted will be rooted up. [14] Let them alone; they are blind guides. And if the blind lead the blind, both will fall into a pit.” [15] But Peter said to him, “Explain the parable to us.” [16] And he said, “Are you also still without understanding? [17] Do you not see that whatever goes into the mouth passes into the stomach and is expelled? [18] But what comes out of the mouth proceeds from the heart, and this defiles a person. [19] For out of the heart come evil thoughts, murder, adultery, sexual immorality, theft, false witness, slander. [20] These are what defile a person. But to eat with unwashed hands does not defile anyone.”
