In the early Christian church, greeting one another with a holy kiss was a customary practice that signified love, unity, and fellowship among believers. It was a physical expression of the spiritual bond that Christians shared, transcending social, cultural, and economic barriers. This practice was rooted in the teachings of Christ, who emphasized love and unity among His followers. While the specific gesture of a kiss may not be common in all cultures today, the principle behind it remains relevant. Christians are encouraged to greet one another warmly and sincerely, reflecting the love and acceptance that Jesus exemplified.
The second part of the verse, where Paul mentions that all the churches of Christ send greetings, underscores the sense of community and interconnectedness among the early Christian congregations. Despite geographical distances, these communities were united in their faith and mission. This unity is a reminder for modern Christians to foster connections and support within the global church, celebrating the shared faith that binds them together. The verse encourages believers to maintain a spirit of love and unity, welcoming each other as members of one spiritual family.
