Peter's instruction to 'greet one another with a kiss of love' reflects a cultural practice of the early Christian community, where such a greeting was a sign of mutual affection and respect. This act symbolized the unity and familial bond among believers, transcending social and cultural barriers. The 'kiss of love' was not merely a formality but a genuine expression of Christian love and fellowship.
The closing blessing, 'Peace to all of you who are in Christ,' serves as a reminder of the peace that Jesus brings to His followers. This peace is not just the absence of conflict but a profound sense of well-being and wholeness that comes from being in a relationship with Christ. It underscores the importance of maintaining peace and unity within the church, as these are vital to the health and witness of the Christian community. By living in peace with one another, believers reflect the love and grace of Christ to the world.
