In Romans 16:16, Paul gives the exact same command to greet with a holy kiss — a direct parallel.

In 1 Corinthians 16:20, Paul again instructs greeting with a holy kiss — identical exhortation.

In 1 Thessalonians 5:26, Paul likewise commands greeting with a holy kiss — consistent apostolic instruction.

Acts 20:37 shows the holy kiss in a tearful farewell — a specific instance of the same early Christian greeting practice.

In 1 Peter 5:14, Peter instructs greeting with a kiss of love — parallels Paul's holy kiss command here.
