‘Judge not’ and ‘cast not your pearls before swine’ sound like opposite instincts — one forbidding discernment, the other apparently requiring it.
Both sayings strip the disciple of any standing to condemn others as a class while still expecting real, costly discernment about what the gospel's holy things require in each actual encounter.
The chapter heading text (KJV)
“Judge not, that ye be not judged… Give not that which is holy unto the dogs, neither cast ye your pearls before swine… Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you… Therefore all things whatsoever ye would that men should do to you, do ye even so to them: for this is the law and the prophets.”
Matthew 7:1–12 KJV
Summary
Bonhoeffer treats ‘judge not’ as removing from the disciple any general permission to sit in condemnation over other people, precisely because the disciple's own righteousness was shown, back in chapter 8, to be an unearned gift rather than a personal achievement that could function as a standard for judging others. The image of the mote and the beam is read straightforwardly: the disciple's own faults are always, realistically, larger and more obstructing than whatever fault they are tempted to point out in someone else.
Read alongside this, the warning against casting pearls before swine sounds at first like a contradictory instinct — a call to discriminate sharply about who deserves the gospel's ‘holy things.’ Bonhoeffer resolves the tension by distinguishing a general condemning attitude, which is forbidden, from a real, situational discernment about when persistent proclamation has become a kind of violence against people who are only using it to mock what is holy. This discernment is not contempt for persons but respect for the gospel's own seriousness.
He reads the following instruction to ask, seek and knock as an assurance addressed directly to disciples wrestling with exactly this tension — unsure whether they have judged wrongly, given up too soon, or spoken where they should have stayed silent — promising that a Father who gives good gifts to imperfect human parents can be trusted with these anxious, real-time decisions about other people rather than requiring the disciple to work them out with certainty on their own.
The chapter arrives, finally, at the Golden Rule, which Bonhoeffer treats as the practical summary of the whole discussion: do to others what you would want done to you removes both the temptation to blanket condemnation and the temptation to a false, indiscriminate tolerance, replacing both with the simple, concrete test of imagining yourself on the receiving end of your own judgment or your own silence. This, he says, is the entire weight of the law and the prophets distilled into something any disciple can actually apply.
Key points
- ‘Judge not’ removes any general standing to condemn others, because the disciple's own righteousness was already shown to be an unearned gift, not a personal standard to judge by.
- The mote-and-beam image insists the disciple's own faults are realistically larger than whatever they are tempted to criticise in someone else.
- Bonhoeffer resolves the apparent tension with ‘pearls before swine’ by distinguishing forbidden blanket condemnation from real, situational discernment about the gospel's own seriousness.
- Ask, seek, knock is read as assurance for disciples anxious about getting these real-time judgment calls wrong — a trustworthy Father, not the disciple's own certainty, carries the outcome.
- The Golden Rule is the practical summary: imagining yourself on the receiving end of your own judgment replaces both blanket condemnation and false tolerance.

For reflection and discussion
- Where have you recently judged someone in a way that, honestly, ignored a larger fault of your own?
- Bonhoeffer distinguishes forbidden condemnation from necessary discernment. Can you think of a real situation where telling the two apart was genuinely difficult?
- Applying the Golden Rule concretely: is there a current judgment of yours that would look different if you imagined receiving it yourself?
