2 Cor. 13:11-14 (ESV)
Finally, brothers, rejoice. Aim for restoration, comfort one another, agree with one another, live in peace; and the God of love and peace will be with you.  Greet one another with a holy kiss.  All the saints greet you.
 The grace of the Lord Jesus Christ and the love of God and the fellowship of the Holy Spirit be with you all.
Greet one another with a holy kiss. I tend to like traditions. Traditions can be good. They can serve to teach. They can create a rhythm of life, making it peaceful and giving it order. Of course there can be bad traditions. Traditionally getting drunk on Friday night, might not be the best of traditions. Then there can be traditions that are neither good nor bad. Or perhaps the context and culture determines whether a tradition is good or bad. Traditions don’t need to be thrown out. But once in awhile they should be scrutinized. We are not bound to them. And for that I am thankful. Giving my elders a kiss, holy or otherwise, before communion is not something I care to do. In our society I think it would have some wrong connotations. Perhaps the handshake is better.
