The back and forth movement can be interpreted to mean that the lives of the two are being entwined into one.Double wedding bands are used, since according to Old Testament references, the placing of rings was an official act indicating that an agreement had been sealed between two parties.
It is noteworthy that the right hands are used in the putting on of the rings, since according to all Biblical knowledge we have, it is the right hand of God that blesses; it was to the right hand of the Father that Christ ascended; it is to the right that those who will inherit eternal life will go.
The rings are then exchanged three times on the fingers of the bride and groom by the Best Man a further expression and witness that the lives of the two are being brought together.
The exchange signifies that in married life, the weakness of one partner will be compensated by the strength of the other.
Apart, the newly betrothed are incomplete, but together they are made perfect.
The second is the Service of Marriage or Crowning, during which prayers are offered for the couple, the crowns of marriage are placed on their heads, the common cup is shared, and the ceremonial walk takes place around the table.
In the Greek Orthodox Tradition, the father accompanies the bride to the entrance of the church, where the groom awaits with her bouquet.
The Koumparos or Koumpara then interchanges the crowns three times as a witness to the sealing of the union.
The wedding crowns, or Stefana, symbolize the glory and honor that is being bestowed on them by God during the sacrament.
The Stefana are joined by a ribbon which symbolizes the unity of the couple and the presence of Christ who blesses and joins the couple.
