Religion is deliberately open-ended (a choice of the game designers). Most Sims believe in a Creator or Overseer. In my SimWorld/ universe, there are many religions, worldviews, and belief systems.
Jacoban and Peteran
There are two inter-related religions similar to Catholicism and Protestantism – Jacoban and Peteran. There are many branches of Peteran, including Angelican.
A Jacoban priest was introduced in The Sims: Medieval, but does not actually make an appearance in the regular Sims world. In my SimWorld, religion does play a part in some Sims lives. The Jacobans believe fear is a mighty tool, and place a high emphasis on conversion, confession, repentance, and following the law. They also lead an ostentatious lifestyle, believing that following the law and tradition makes one healthy and wealthy. Jacobans worship the Creator and their relationship with him is based on fear, order, and laws. Jacobans have priests. See more.
- The Loyoleans are a branch of the Jacoban faith, and are responsible for the Simspani missions across the SimNation. They founded Starlight Shores, and set up the wishing well in Lucky Palms. They specifically set up fountains in each town they placed a mission. They are a play on the Spanish missions of California.
- A Devoutarian is a branch of the Jacoban faith, and is my SimWorld version of the Orthodox church.
A Peteran is also introduced in The Sims: Medieval, but similarly, doesn’t make an appearance in the regular Sims world. In my SimWorld, Peteran is a religion just like Jacoban. They believe in living simply, loving the followers, and place a high emphasis on evangelism, prayer, community, peace, and relationship with God. Peterans worship the Almighty Father, whom they affectionately call Padre. Their relationship with him is based on love and acceptance. Peterans have ministers. See more.
- An Angelican is a type of Peteran, though closely related to the Jacobans. Angelicanism is closest to Anglican and Episcopalian. They broke away from the Jacoban church because they didn’t like the mandated state religion and wanted a separation of church and state in the Sim Union.
Both the Creator and Padre are one in the same God, different aspects and interpretations of God. In both the Jacoban and Peteran faiths, they believe the first two created people in the world were Simdon and Eve (like Adam and Eve in the Simlish language).
Another religion is the worshippers of the Maker, also known as Al-Sim. They worship at a temple known as the House of Al-Sim. Children of Al-Sim have strict rules for living. Women and children must have no outer adornments, dress in extreme modesty, adhere to curfew, and be submissive. Their religion teaches separation from mainstream culture, high respect for elders, dominant male authority, and arranged marriages.
- Papyrus is considered an angelic messenger in Al-Sim.
Simdui Spirituality or Simduism (as it is known to most of the world) is another religion, practiced most prominently in Simbai, some of the Osimceana islands, and some of the Simirribbean Islands. Those who follow Simdui Spirituality worship a pantheon of gods and goddesses. Simdu Spirituality teaches the principles of balance, harmony, meditation, self-restraint, family, peace, forbearance, compassion, and charity. Those who follow Simdui allow the principles to guide their code of ethics, concepts of prosperity, work, freedom, and liberation, how to channel their emotions and sexuality, and their beliefs about actions, intentions, and consequences. Some followers choose to live as monastics in a life of prayer, meditation, solitude, reflection, chastity, and poverty. The first queen of Simbai, Yu La, is also revered in Simduism, thought to represent the Queen of Heaven.
Anima is the religious practices, philosophies, and beliefs of the Nativians. Those who practice Anima believe that there is no distinction between the spiritual and physical world and everything has a ‘spirit’ or an ‘animan.’ There is a mother goddess or an world caretaker called Nokoina, and she is believed to be the caretaker of natural world and a goddess of life, love, and animals. Anima teaches high respect of nature, simple lifestyle, balance, harmony, and finding inner sanctuary and peace. They do not have an organized church, but often gather in communities for celebrations and rituals. The highest spiritual healer and leader of a community or village is called an Olos, meaning ‘one who makes whole,’ and can only be a female.
Sutuai is the Simpanese version of Anima. It includes honoring ancestors, honoring the spirits of animals, respecting nature, seeking peace and balance, practicing kindness, discerning wisdom, and revering the Sacred Power.
Cult of Veni
Some SimNatives still worship the goddess, Venivea, more commonly known as Veni (a.k.a. Venus), the goddess of love, from their old days on Venusia. This is extremely rare and there are only a few known cults today. See more.
As an aside, the Grim Reaper is the closest version of the devil or personification of death in the SimWorld. He only comes when a Sim is dying, of course. Some Sims believe he is an ancient god of the underworld (like in Veni, they believe the Grim Reaper is the god, Morsim) and some believe he is an alien from another planet. Others know him as the king of the Kr’v.
