The Prohibition Against Judgmentalism
Matthew 7:1–5 contains not a universal ban on discernment but a precise prohibition against the censorious, fault-finding spirit that delights in the shortcomings of others. Working through three movements — the prohibition itself, Christ's explanation of its consequence, and the plank-and-speck illustration — the sermon establishes that judgmentalism is a serious sin condemned by Christ on the Mount, one attended by self-righteousness, a lack of charity, and a practical denial of remaining corruption in oneself. The application calls believers to seek the Spirit's influence, apply biblical law evenhandedly, pursue humility, and let the cross be the death knell of self-righteousness.
The Warning Against Causing Offense
Matthew 18:5–9 confronts the damning danger of causing offense — the Greek scandalon — to Christ's 'little ones,' those who believe in him. The passage divides the threat into two categories: offenses arising from a godless world that inevitably opposes the people of God, and offenses that arise from within the covenant community through moral corruption and intellectual perversion. Jesus' language is extreme by design — a millstone pulled by a donkey hung around one's neck and cast into the depths of the sea is declared preferable to the eternal consequences awaiting those who ensnare a brother or sister in sin. The sermon calls believers to receive one another with genuine humility, to deal radically with whatever personal sin or liberty causes another to stumble, and to take seriously the eternal weight of their influence within the church.
The Third Commandment: Oath-Taking
Jesus' instruction in Matthew 5:33–37 is not a universal prohibition against oath-taking but a condemnation of the Pharisaic practice of swearing by created things — heaven, earth, Jerusalem, one's own head — as a device to lend apparent solemnity to speech while evading accountability to God. The sermon exposes this abuse by tracing the Old Testament's positive teaching on oaths, demonstrating from Christ's own submission to adjuration in Matthew 26 and from Paul's sworn affirmations that lawful oath-taking remains valid. The corrective Jesus offers is the kingdom ethic of simple truthfulness: the citizen of Christ's kingdom needs no oath to be believed, because his yes is yes and his no is no, and any compulsion to pad speech beyond this reveals the depraved bent traced ultimately to the father of lies. The Sermon on the Mount, rightly understood, drives the hearer to the cross, where Christ — who honored every commandment and swore to his own hurt — provides the righteousness no oath-keeper can supply for himself.
