A handfasting wedding is a traditional practice that can define an unofficiated wedding, a betrothal, or a temporary wedding, depending on the usage of the term. The phrase refers to the making fast of a pledge by the shaking or joining of hands. Handfasting is a symbolic unity ritual in which a couple stands face to face as their hands are tied together, hence the phrase "tying the knot". The couples hands are bound, and they can recite words that express their commitment to one another. Handfasting rituals are associated with Pagan ceremonies, but they are now often seen in secular, spiritual, and even some Christian ceremonies. The handfasting ceremony dates back over 2000 years and is an ancient Celtic tradition that was originally used to symbolize a betrothal, during which a druid priest would declare that the couple would be bound together. In later times, it was used in a marriage ceremony, in lieu of the presence of a priest. Today, handfasting ceremonies are a wonderful way to personalize a wedding ceremony and are particularly common among couples from overseas getting married in Ireland and Scotland.
