What does the Bible say about greetings among Christians?

In the New Testament, especially in the letters of the Apostle Paul, we find recurring themes of greeting one another. For example, in 2 Timothy 4:19, Paul instructs Timothy to greet Prisca and Aquila, showcasing the bond that exists among believers. This practice of greeting is significant because it emphasizes our identity as brothers and sisters in Christ, united by the blood of Jesus. Furthermore, it showcases God's work within His people, as even in informal greetings, there is an acknowledgment of the relationships that God has forged within the community of faith.
