In this verse, Paul encourages the Corinthian church to greet one another with a holy kiss as a sign of love and unity among believers. This practice was a common cultural custom in the early church that symbolized affection and mutual respect. By emphasizing this gesture, Paul underscores the importance of genuine relationships and harmony within the body of Christ. The holy kiss serves as a reminder for Christians to express their love and support for one another, fostering a spirit of peace and goodwill in the community of faith.
