In the command to greet one another with a holy kiss, the kiss is of secondary importance. The command is actually to greet one another, and the kiss was simply the way in which that would ordinarily happen. The burden of the command is upon the greeting rather than the kiss. The command is to extend a holy greeting, and there are at least four things from this text that a holy greeting implies.
The pattern of Christ is suffering and then glory; humility before exaltation. As his people we can enter into that pattern. This means our call to humility is raised to a glorious sharing in his humilityóa humility we share toward one another.
