The thoughtfulness of love will suggest the appropriate means, but some emphasis may rightly be given to the phrase in Christ’s counsel: “between thee and him alone.” Let there be an opportunity for a frank and private conversation. To appeal to an estranged friend in front of witnesses induces to special pleading, making the witnesses the jury, asking for a verdict on either side. And the result is that both are still convinced that they have right on their side and that they have been wronged.
