What is a Holy Kiss?

Last week, someone anonymously placed a card (like those we used for question and answer Sunday) in the collection plate asking what a “holy kiss” is? They also listed several scripture references where the term appears. This is an excellent question, and I’m glad that it was asked, but I’ll save it for the next question and answer Sunday. If it was your question and you don’t want to wait until then just let me know and I’ll go ahead and give you an answer.
