Just got a chance to go to TCS and I noticed that I have become the Jewish wedding maven. That is a very nice compliment.
I did a quick search of synagogues in WV and there are none that say Orthodox. One in Charleston, Congregation B'nai Jacob, proclaims that it is traditional, but an Orthodox synagogue would say that it Orthodox. So, I do not think that you need to worry about the men and women sitting separately.
Before getting to the synagogue, there are some things to do to prepare.
First of all, if you are giving the bride and groom money, the number 18 has some significance in Judaism. So, for luck, money should be in multiples of 18 because that is associated with life.
There may be kippot (yarmalkes) awaiting for the men over 13 when you enter. Wearing one is correct for all men. They sometimes have the bride and groom's name printed on the inside and can be taken with you.
This is also the time to look for a handout about what to expect during the ceremony so you have the background that explains things. Either it will be near the kippot or there will be someone handing them out to you.
The parents do escort the bride up to the huppah, the canopy, where the groom is waiting. Then, it is a relatively short ceremony. It is nothing like a Catholic mass with the wedding ceremony. A Jewish wedding is a separate event from all other religious events.
For attire, business suits are always fine for men. A men should wear a kippah (from the table at the door) unless it totally goes against his religious beliefs. In most cases it should not because it is just a hat to wear in the synagogue.
For the women, it is not appropriate unless you are Jewish (IMO) to wear a kippah on your head. What you need to wear is proper clothing. Make sure that your shoulders are covered. If you want to wear a spaghetti strap, low cut dress to the party, then bring a shawl for the ceremony.
When the bridegroom stamps on the glass (it may be a lightbulb these days) and it brakes, say, "Mazeltov!"
The reception will most probably be Kosher. That means that meat and dairy do not mix. You are most likely to have a chicken or a fish main meal because desserts and the milk you put in you coffee are not meat and cannot be served in the same meal as dairy/chicken.
The first thing that will be done before the meal can be eating is the blessing over the Challah, the bread. The blessing is:
Transliteration: Barukh ata Adonai Eloheinu melekh ha‑olam, ha‑motzi lehem min ha‑aretz.
Translation: "Blessed are you, LORD, our God, King of the universe, who brings forth bread from the earth."
Respond with, "Ah Main" accent on the last syllable.
Also, the toasts at the reception afterwards should be answered La Chaim - to life.
Have fun at the reception! Dance the Hora when the bride and groom are lifted up! Celebrate with them on their wedding day!
A little conversational piece...We get a Ketubah right before the ceremony. It is an ancient contract that has a way to give a woman what is rightly hers from the protection of her husband, like a dowry. If it has a "get" clause, then the husband must accept and give his wife a divorce as per Jewish law. BTW, our Ketubah does not have one but we have been married for a number of years so I guess we don't need one.
WOW! That was a long reply! PM me if you want more info!
