Matthew 15

The text moves from a debate over the validity of religious authority to the definition of true purity, demonstrating that spiritual legitimacy rests in God’s Word rather than human innovation.

• The promise that faith leads to divine response: 'be it unto thee even as thou wilt' (v28).
• The promise of healing for those who persist in seeking Him (v28, v30).

• The command to honor parents: 'Honour thy father and mother' (v4).
• The directive to the crowd: 'Hear, and understand' (v10).
• The instruction to the disciples: 'Let them alone' regarding the Pharisees (v14).

• The warning against vain worship: 'In vain do they worship me' (v9).
• The warning of judgment on ungodly human inventions: 'Every plant, which my heavenly Father hath not planted, shall be rooted up' (v13).
• The warning of leading and following the spiritually blind: 'both shall fall into the ditch' (v14).

• The Pharisees (Φαρισαῖος [G5330]) were a religious group focused on strict adherence to the Law and the oral traditions of the elders.
• The 'corban' practice mentioned involved dedicating money to God to avoid supporting elderly parents, effectively using a religious loophole to bypass the commandment.

• Ceremonial hand washing (νίπτω [G3538]) was a specific tradition not commanded in the Mosaic Law but practiced to ensure ritual purity before eating.
• The social stigma between Jews and Gentiles in the regions of Tyre and Sidon made the woman's interaction with Jesus culturally transgressive.

• Matthew 15 functions as a pivot point, highlighting the corruption of the current religious establishment and setting the stage for the Gospel to extend beyond Jewish boundaries.

• Jesus cites the fifth commandment (Exodus 20:12) to correct the Pharisees.
• The quotation from Isaiah 29:13 is used to diagnose the spiritual state of the religious leaders.
• Matthew Henry observes that the Pharisees' teaching of 'tradition' was essentially an attempt to improve upon God's wisdom, which invariably leads to disobedience.
• There is an ongoing theological tension regarding the 'lost sheep of the house of Israel' (v24) vs. the 'Great Commission' later in the Gospel. Reformed theology often treats this as a display of the historical priority of the covenant people, whereas other views may emphasize the universal offer of grace even in Jesus' earthly ministry.

• Isaiah 29:13 is quoted to describe the hypocrisy of those who honor God with their lips but whose hearts are far from Him.
• Leviticus 20:9 is the basis for the punishment for reviling parents mentioned in v4.

• τότε (tóte) [G5119]: Often used in Matthew to signify 'then' as a temporal marker of consequence or progression.
• νίπτω (níptō) [G3538]: Specifically refers to washing parts of the body (hands/feet/face), distinguishing it from total ritual immersion.
• παράδοσις (parádosis) [G3862]: Meaning transmission or precept; here used negatively to describe human-origin traditions.
• ἀκυρόω (akyróō) [G208]: To invalidate or deprive of authority; used to describe how the Pharisees' traditions rendered the law ineffective.

• The shift from the Pharisees' concern with outward purity (hands) to Jesus' focus on internal purity (heart).
• The specific detail that Jesus 'answered her not a word' (v23) before ultimately honoring her faith, demonstrating a pedagogical trial of her persistence.

• Scholars debate the exact nature of the Pharisaic 'traditions' referred to here—whether they were intended as 'fences' around the Law or were viewed by the Pharisees themselves as equal to the Law.
• There is theological debate concerning the 'lost sheep' (v24); some argue this confirms a limited scope of the atonement during Jesus' earthly ministry, while others view it as a chronological priority for the covenant people without excluding the eventual mission to the Gentiles.
