Laying the Groundwork
As Jesus went about “preaching the gospel of the kingdom” (Matt. 4:23),1 in many respects his earthly ministry was preparatory and an early transitional period between old-covenant Judaism and the establishment of his universal church. It was not the time to set aside the Mosaic Law, nor was it the time to teach exclusively Christian doctrine. It was, however, necessary to prepare the way for God’s approaching kingdom.2
Chapter 5 of Matthew’s Gospel is part of a three-chapter discourse, wherein the Lord’s celebrated “Sermon on the Mount” is recorded. Jesus’s immediate listening audience was Jewish, inclusive of but not limited to his disciples. Matthew’s targeted reading audience was a Jewish-Christian community not far removed from Jesus’s original listening audience in time, geographical location, political environment, and sociocultural circumstances.3
In chapter 18 of Matthew’s Gospel, the Lord’s recorded words are directed to “the disciples,” who would later be commissioned to spread Christ’s message to all nations.
When My Brother Has Something Against Me
“Therefore if you bring your gift to the altar, and there remember that your brother has something against you, leave your gift there before the altar, and go your way. First be reconciled to your brother, and then come and offer your gift” (Matthew 5:23-24).
The directive here, set in the context of early-first-century Jewish worship, is subsequent to proscriptions against being angry, unforgiving, prideful, spiteful, malicious, and hateful (vv. 21-22)—the opposite of the blessed attitudes and behaviors highlighted at the beginning of the sermon. The “gift” [δῶρον] brought to the altar, generically representing any offering presented at the temple, is an offering of worship.4
One cannot worship God acceptably without faithful adherence, both inwardly and outwardly, to his revealed will. Instead of mindless ritualism, genuine worship, “in spirit and truth” (John 4:23-24), involves intent, purpose, and the right frame of mind. Worship that is acceptable and pleasing to God begins in the heart and should be prioritized as “first” [πρῶτον], of utmost importance (Matt. 5:24b). Otherwise, any so-called worshipful act is vain, empty, meaningless (Matt. 7:21-27; 15:5-9; 21:13).
The realization that “your brother has something against you” is a matter of interpersonal relations and brotherhood. Considering the requisite of self-examination and fidelity of spirit,5 even if you think the disharmony or negative feelings are not entirely your fault, the responsibility is on “you” to take the initiative and seek reconciliation. “Behold, how good and how pleasant it is for brethren to dwell together in unity!” (Psa. 133:1). “Let no one seek his own, but each one the other’s well-being” (1 Cor. 10:24).
When I Have Something Against My Brother
Jesus, having taught an object lesson about childlike innocence and humility, stressed the absolute importance of saving a single soul (Matt. 18:1-14). He then addressed a disciple’s duty toward a sinning brother.
“Moreover if your brother sins against you, go and tell him his fault between you and him alone. If he hears you, you have gained your brother. But if he will not hear, take with you one or two more, that ‘by the mouth of two or three witnesses every word may be established.’ And if he refuses to hear them, tell it to the church. But if he refuses even to hear the church, let him be to you like a heathen and a tax collector” (Matthew 18:15-17).
One of the challenges of this passage is whether or not the prepositional phrase “against you” [εἰς σὲ] is original to the text. While most Greek manuscripts include these words, some important textual witnesses do not. Text critics, translators, and exegetes must therefore determine if v. 15a should read broadly, “if your brother sins” (NASB, NET, NIV), or more specifically, “if your brother sins against you” (ASV, CSB, ESV, N/KJV, RSV).
o In favor of the shorter reading is the exclusion of the phrase from early Greek texts (incl. Sinaiticus, Vaticanus, Origen). Its presence in later copies is explained as textual gap-filling, perhaps an inference from v. 21.6
o In support of inclusion is the adjoining phrase, “between you and him alone” (v. 15b), followed by “let him be to you [singular] ...” (v. 17b), as well as Peter’s follow-up question, “how often shall my brother sin against me [εἰς ἐμὲ], and I forgive him?” (v. 21). The majority of witnesses, representing all text families, contain the words in question. Inadvertent omission from a few copies is understandable if copyists transcribed the audible reading of the text, where the words ἁμαρτήσῃ εἰς σὲ (“sins against you”) combine expressions with vowel sounds (ῃ, ει, ε) that are similar when read aloud in Greek: ἁμαρτήσῃ (pronounced ha-mar-tay-say) and εἰς σὲ (pronounced ays-seh).7
o Because of the “balance of possibilities,” the Nestle-Aland and UBS Greek texts include the words in [square brackets].8
At the end of the day, the immediate context, the overall context of scripture, and the “brother’s keeper” principle require application of both readings.9
The procedural guidelines that follow would surely apply if my brother sins against me. The verb “sins” [ἁμαρτήσῃ] is not descriptive of someone’s mere inconsideration or petty offense that might hurt my feelings, although heeding the Lord’s counsel would still be helpful in such cases. The Bible makes a clear distinction between persistent transgressions that jeopardize one’s soul, calling for disciplinary action in the church, and trivial matters or civil disputes that do not (1 Cor. 5:1–6:18).
To be like Christ and to follow his direction, we are called to be selfless, and if necessary, willing to suffer personal wrong (perceived or otherwise) rather than seeking retaliation or damaging the unity and reputation of his church (1 Cor. 6:7-8).10 Whether I am personally offended or not, the issue the Lord addresses is a trespass or wrongdoing that violates the holiness of God and his revealed will. His standard of judgment overrides my own (Rom. 2:1-8; 14:4).
But what if my brother sins (in general) without directly affecting me? Can I legitimately say, “Well, the sin is not against me personally, therefore these procedural guidelines do not apply”? Notwithstanding the textual variant involving wider applicability (noted above), Jesus goes on to make particular application within “the church” [ἡ ἐκκλησία] (Matt. 18:17).
Alluding to the congregated followers of Christ and community of the saved, the term ἐκκλησία occurs only three times in the Gospel accounts, all in Matthew, all in the teachings of Christ. Having promised to build his “church” (Matt. 16:18), Jesus then provided instruction for how sin is to be dealt with in his church (Matt. 18:15-17). Whether or not the recognized sin is of a personal nature, its adverse effects have broader implications if left unaddressed, and if ineffectually handled, it necessarily becomes a congregational matter.
“Sin is like quicksand: Your own efforts only make you sink deeper. Only an outside hand can pull you out” (author unknown). It was never the Lord’s intention for his followers to be segregated or isolated or independent in their Christian walk. The word “church” always applies to a collectivity of believers, never individually, and Jesus’s emphasis on “one another” proliferates in the writings of his inspired emissaries.11
Further Commentary
“Brethren, if a man is overtaken in any trespass, you who are spiritual restore such a one in a spirit of gentleness, considering yourself lest you also be tempted. Bear one another’s burdens, and so fulfill the law of Christ” (Gal. 6:1-2).
“Brethren, if anyone among you wanders from the truth, and someone turns him back, let him know that he who turns a sinner from the error of his way will save a soul from death and cover a multitude of sins” (Jas. 5:19-20).

9 The same textual issue occurs in Luke 17:3: “If your brother sins” (ASV, CSB, ERV, ESV, ISV, NASB, NET, N/RSV), or “If your brother sins against you” (NIV, N/KJV, WEB), although in the very next verse, the “against you” [εἰς σὲ] inclusion is undisputed among textual witnesses.
