Feast in the context of "Monreale Cathedral"

Religion is a range of social-cultural systems, including designated behaviors and practices, ethics, morals, beliefs, worldviews, texts, sanctified places, prophecies, or organizations, that generally relate humanity to supernatural, transcendental, and spiritual elements—although there is no scholarly consensus over what precisely constitutes a religion. It is an essentially contested concept. Different religions may or may not contain various elements ranging from the divine, sacredness, faith, and a supernatural being or beings.

The origin of religious belief is an open question, with possible explanations including awareness of individual death, a sense of community, and dreams. Religions have sacred histories, narratives, and mythologies, preserved in oral traditions, sacred texts, symbols, and holy places, that may attempt to explain the origin of life, the universe, and other phenomena. Religious practice may include rituals, sermons, commemoration or veneration (of deities or saints), sacrifices, festivals, feasts, trances, initiations, matrimonial and funerary services, meditation, prayer, music, art, dance, or public service.

The Passover Seder is a ritual feast at the beginning of the Jewish holiday of Passover. It is conducted throughout the world at the start of the 15th day of Nisan in the Hebrew calendar (at sunset, when a Hebrew day begins). The day falls in late March or in April of the Gregorian calendar. Passover lasts for seven days in Israel, and customarily usually eight days in the Jewish diaspora. A seder is held on the first night, the 15th of Nisan; where eight days are observed, a seder is often also held on the second night.

The Seder is a ritual involving a retelling of the story of the liberation of the Israelites from slavery in ancient Egypt, taken from the Book of Exodus (Shemot) in the Torah. The Seder itself is based on the Biblical verse commanding Jews to retell the story of the Exodus from Egypt: "You shall tell your child on that day, saying, 'It is because of what the LORD did for me when I came out of Egypt.'" (Exodus 13:8) At the seder, Jews read the text of the Haggadah, an ancient Tannaitic work narrating the Israelite exodus from Egypt, with special blessings and rituals, Talmudic commentaries, and Passover songs.
