The Greek word diallássō, represented by G1259, means to reconcile or to change thoroughly and conciliate. It appears only 1 time in 1 unique verse in the Bible, highlighting its specific and powerful application in the context of interpersonal relationships. Its core meaning involves a thorough mental change leading to conciliation.
The sole biblical use of G1259 is found in Matthew 5:24, where Jesus instructs that if someone brings a gift to the altar and remembers their brother has something against them, they should first be reconciled before presenting their offering. This command prioritizes relational restoration over religious ceremony, framing reconciliation as a necessary precursor to acceptable worship. The act of being reconciled G1259 is presented as an urgent, primary action.
Several related words in the surrounding text clarify the context of reconciliation:
- G863 aphíēmi (leave): This word commands the worshipper to leave their gift, meaning to send it forth or put it away. It highlights the physical act of pausing worship to pursue reconciliation Matthew 5:24.
- G2379 thysiastḗrion (altar): This term refers to the altar, a place of sacrifice. Its presence underscores that reconciliation is required even at the most sacred point of religious observance Matthew 5:24.
- G80 adelphós (brother): This word for brother can be taken literally or figuratively. The command to reconcile applies to relationships within the community of believers, not just immediate family Matthew 5:24.
The theological weight of G1259 is significant despite its single use, establishing a foundational principle for Christian conduct.
- Primacy of Reconciliation: The command to "first be reconciled" G4412 before offering a gift establishes that relational harmony is a prerequisite for authentic worship. God prioritizes restored relationships among people before accepting their offerings Matthew 5:24.
- Active Pursuit of Peace: The instruction to "leave" G863 the gift and "go thy way" G5217 frames reconciliation not as a passive hope but as an active, urgent duty that requires initiative.
- Foundation for Worship: The context of bringing a gift to the altar G2379 shows that human relationships and divine worship are deeply intertwined. An unreconciled state with a brother G80 hinders one's ability to properly approach God.
In summary, G1259 diallássō is a term focused on active reconciliation. Though it appears only once, its placement in Matthew 5:24 gives it immense weight. It teaches that mending broken relationships with a brother is not an optional activity but a foundational requirement that must be addressed even before completing an act of worship like offering a gift at the altar. The word encapsulates the principle that our horizontal relationships are inseparable from our vertical relationship with God.
