Passover

A lamb.

The question about the reclining used to be about the Korban Pesach, but since that isn't around, it was changed to the current version

joy and happiness after escaping slavery.

Rabbis determined that if flour is baked within 18 minutes of water being added, it doesn't have time to begin the natural leavening process.

The two Shabbos (Sabbath) candles represent Zachor (Exodus ch. 20, remember the shabbos) and Shamor (Deuteronomy ch. 5, keep the shabbos). All of the Yamim Tovim (festivals), Pessach (Passover) included, are also termed "shabbos" and share in many of the shabbos laws and observances, including lighting two candles shortly before the holy day begins.

No. A Seder is a Jewish religious meal recalling the Passover.

the seder plate is an important part of it

Is the decision truthful?Is it fair to all concerned?Will it build goodwill and better friendships?Will it be beneficial to all concerned?

You might be able to find kosher for Passover wafer cones, however, they will have to be certified as such by a reputable hechsher.

Blood was painted on the door posts of the homes of the Israelites the very first Passover in Egypt. This was so that the angel of death new which homes to pass over. This was a one time event.

According to Jewish law, one is required to eat matzah at the Passover seder,
on the first night of Passover, and also on the second night if outside of Israel.

For the remainder of the holiday, the Jew isn't required to eat bread at all. But
if he does feel like it, then it should be the unleavened kind.

You can be yourself without being made to feel ashamed of it!

There was a 7-branched menorah which was lit in the Temple in Jerusalem (Exodus ch.25). After the Greeks desecrated the Temple only a small container of pure olive oil was found and this oil miraculously lasted 8 days until more could be obtained. The festival of Hanukkah commemorates this miracle and also the victory of the Maccabee rebels in their revolt against the Greeks. A special menorah (hanukkiah) with places for 8 candles (+ 1 "service" candle) is lit on each night of Hanukkah. Many people use olive oil instead of candles. After sunset (or later) one candle is lit on the first night, two on the second, etc. On Friday nights, Hanukkah candles are lit before Sabbath candles, and larger candles are used so that they will burn until after dusk for the required time.

Baklava, which is made with phyllo dough, is chametz.

There are a number of companies that make kosher l'Pesach imitation soy sauce. As soy beans are considered kitniyot, imitation soy sauce emulates the taste of the real thing but does not contain any soy.

The Feast of Unleavened Bread

The Occasion of our Freedom

The Jews eat the Passover Seder meal on the night of Passover (Pesach). It makes little difference whether Passover begins on Shabbat or on a weekday. Note that there are festive meals on every Shabbat, but they are not called "seder" and the foods are different.

In the seder meal the parsly, or other type of bitter herb, represents the bitter taste of slavery and affliction. In some homes parsley is used because it looks similar to a flail.

Gratitude to God. Pesach (Passover) is important to us since in it we relive the Exodus from Egypt and our birth as a nation, both of which were preparations for receiving the Torah from God.
The highlight of Passover is the Seder meal. This meal is of great importance in Judaism. It is a 3325-year old continuous tradition that began on the night of the Exodus from Egypt (see Exodus chapter 12), and is fully detailed in our ancient Oral Traditions (Talmud, chapter Arvei Pesachim).
The Seder meal is one of those occasions, like Yom Kippur and Hanukkah, that Jews all over the world, Orthodox and non-Orthodox alike, observe in common. During the Seder, we keep the essential mitzva and customs of handing Jewish traditions down to the next generation, with the traditional Seder foods and the ceremony of reading the Passover Haggadah which retells the events of the Exodus.
During the Seder meal, other traditional foods are eaten in addition to the matzah: bitter herbs, parsley, wine and haroset (see below). Salt water, a roasted egg, and a bit of roasted meat are also on the table.
During all the days of Passover, matzah (unleavened bread) is eaten; while leavened foods such as bread, cake, cookies, cereal and pasta are forbidden. Certain prayers are added in the synagogue services, and the Torah is read each day.
Here is the symbolism of the items on the Seder plate:
The bitter herbs (maror) symbolize the harsh slavery which the Israelites suffered in Egypt. Either horseradish or romaine lettuce is traditionally used for maror.
Charoset - A sweet mixture representing the mortar used by the Jewish slaves to build the storehouses of Egypt. In Ashkenazi Jewish homes, charoset is traditionally made from chopped nuts, grated apples, cinnamon, and sweet red wine.
Karpas - A vegetable other than bitter herbs, traditionally parsley, which is dipped into salt water at the beginning of the Seder. The dipping of a simple vegetable into salt water (which represents tears) recalls the pain felt by the Jewish slaves in Egypt.
Beitzah - A hard-boiled egg, symbolizing the korban chagigah (festival sacrifice) that was offered in the Temple in Jerusalem and roasted and eaten as part of the meal on Seder night. Although both the Pesach sacrifice and the chagigah were meat offerings, the chagigah is commemorated by an egg, a symbol of mourning.
Z'roa - A roasted lamb or goat shank-bone, chicken wing, or chicken neck; symbolizing the korban Pesach (Pesach sacrifice), which was a lamb that was offered in the Temple in Jerusalem, then roasted and eaten as part of the meal on Seder night.

The first plague was all the water of the egyptians water to blood so the king would let gods people go, but they refused. The second was frogs everywhere, including in their beds. Third was gnats and/or lice but still they refused. Every time he (the king of Egypt) refused god added a then further plague. the fourth was flies roaming, the 5th was livestock became diseased and so the king agreed, only then to change his mind. so then came the 6th, which was boils. the 7th plague was continuous thunder and hail which flattened all of their crops. locusts was the 8th plague and darkness was the 9th and the final was the death of the first born of every Egyptian family. the king the agreed to let the leave, so to celebrate, gods people had the first passover meal and left. but the king planned to steal them back just as they was approaching the river nile the saw them. moses prayed to god and he parted the water and brought it back so the king couldn't get them - by Jayme 12yrs old :)

One of the "appatizer" courses of the traditional Seder meal is a green vegetable (frequently parseley, but I suppose lettuce would do) dipped in salt water. Tradition holds that the salt water represents the tears of the Hebrew slaves. This fits into one of the main purposes of the Seder ritual, to recall and to some extent relive the experience of liberation from slavery.

Matza goes great with many things. My personal favorites are Matza with cream cheese, cream cheese and jellie, and Matza with cheese cooked onto it. Be aware, however, that on Passover some don't put spreads on their matza - called gebrukts, because there might be some flour that didn't get mixed with water, and the spread will make it become chametz.

For the Catholics Christian. it is very important because a better knowledge of the Jewish people's faith and religious life as professed and lived even now can help our better understanding of certain aspects of Christian liturgy.

For both Jews and Christians Sacred Scripture is an essential part of their respective liturgies: in the proclamation of the Word of God, the response to this word, prayer of praise and intercession for the living and the dead, invocation of God's mercy. In its characteristic structure the Liturgy of the Word originates in Jewish prayer.

The Liturgy of the Hours and other liturgical texts and formulation, as well as those of our most venerable prayers, including the Lord's Prayer, have parallels in Jewish prayer. The Eucharistic Prayers also draw their inspiration from the Jewish tradition. The relationship between Jewish liturgy and Christian liturgy, but also their differences in content, are particularly evident in the great feasts of the liturgical year, such as Passover. Christians and Jews both celebrate the Passover.

For Jews, it is the Passover of history, tending toward the future; for Christians, it is the Passover fulfilled in the death and Resurrection of Christ, though always in expectation of its definitive consummation.
