How beautiful. How old are these traditions? I love that those two young people wanted to honor the traditions.
From what I understand...
The ceremony being in 2 parts is from Jewish/old testament times.
The first part, the betrothal, including the exchange of rings is from ancient times. In the service, the prayer at the rings includes this " By a ring power was given to Joseph in Egypt; by a ring was Daniel glorified in the land of Babylon; by a ring was the uprightness of Tamar revealed; by a ring our heavenly Father showed His bounty upon His son; for He said: Bring the fatted calf and kill it, and let us eat and make merry."
The Jews in ancient times did have a second part of the service, that was the actual wedding, but I do not think they had crowns, hand ties, wedding cup, or wedding rug. I am not sure on that though. All the various kinds of Orthodox Christian have the crowning, candles, and a wedding cup. And those parts have been around since super early (before 300). The hand tie and wedding rug is only done by some Orthodox jurisdictions, not all, so might be a bit later (but still early, before middle ages at a guess).
And... a number of Orthodox now wear modern dress and start the ceremony with the standard American entrance.
But... the kids wanted to do it all traditional. And the bodice that the Bride is wearing is from 1760 or something. Crazy cool.
Traditionally, the parents of the bride provide a matching set of icons to the bride and groom. One of Christ and one of His mother. The icons are brought to the ceremony, and then to the reception, and then used in the house of the new couple to start their icon corner.
And the rug (in those traditions that do the rug), is made by the parents of the groom, and is to be their prayer rug.
