The Warning Against Heresy

Jim ButlerMatthew 16:5–12

Matthew 16:5–12 records Christ's warning to His disciples to 'take heed and beware of the leaven of the Pharisees and the Sadducees' — a command the disciples immediately misread as a remark about physical bread. This exposition works through three movements: the warning Christ issues, the disciples' failure to comprehend it, and the clarification Christ graciously provides. The sermon argues that a small doctrinal error, like leaven, silently pervades and corrupts an entire religious system, and draws direct lines from Pharisaic works-righteousness and Sadducean rationalism to contemporary threats — Arminianism, Roman Catholic merit theology, and theological liberalism. The congregation is urged to prize the means of grace, resist the addition of human tradition to Scripture, and rest in justification by faith alone in Christ alone, recognising that it is revealed truth, not human will, that produces saving faith.
