In the ancient world, letters were typically dictated to scribes, who would write them down. By stating that he writes the greeting in his own hand, Paul is emphasizing the personal nature of his communication. This small but significant gesture adds a layer of authenticity and personal connection to his message. It assures the recipients that the letter is genuinely from him, not just in content but in form. This personal touch would have been especially meaningful to the early Christian communities, who often faced challenges and needed reassurance of their leaders' support and guidance.
Paul's decision to write the greeting himself also highlights the importance he places on his relationship with the Corinthians. It is a way of expressing his love and commitment to them, reinforcing the bond between them. In a broader sense, this act can be seen as a reminder of the personal nature of Christian fellowship and leadership. It encourages believers to value personal connections and authenticity in their relationships, both within the church and beyond. By taking the time to write with his own hand, Paul demonstrates the care and attention that should characterize Christian interactions.
