Many of the OTL religions are present in this timeline. That said, polytheistic religions are much more common, and maintain a prominent role in societies and governments in the world.
The state religion of the Egyptian Empire, and the most common in the nation. Most Egyptian families possess patron deities that generally is generational. In other words, one family generally has a history of worshiping one god primarily over another. For example, Seti XIV, the current Pharaoh of the Empire, has the god Set as the patron deity of his family.
The state religion of the Roman Republic. In this timeline, there no Resurrection story, as the historial figure of Jesus was not crucified, due to a series of different events.
After driving out the money lenders, he attracts the ire of the high ranking temple officials, who hold much sway in the court of the King of Jerusalem (who at this point was a vassal of the Egyptian Empire). While the King himself did not take much heed to it, the bureaucrats demanded his execution. The King, not interested in dealing with this issue, was prepared to perform the execution, only to have his decision overruled by the Egyptian representative of the Pharaoh.
Fearing the possibility of revolt by the followers of Jesus, the Egyptian administration decided to compromise. They made an offer to the Temple priests to arrest Jesus, and bring to Egypt, and keep him imprisoned for the rest of his life. The priests agreed, and the Egyptians had Jesus transported to a prison in Egypt.
While it is taught that he made hundreds of converts while in prison, Egyptian records say that his converts did not go beyond other prisoners.
The major symbol of Christianity is a chain, instead of a cross, as Christ spent his remaining years in chains.
In a similar strain to Christianity, there are not that many prominent differences with Jewish practices in this timeline. However, a notable difference is the depiction of the Book of Exodus. Since the Israeli region remained under the control of the Egyptians, and many Jews identify as Egyptian nationally, the story of the Exodus does not so much celebrate victory over the Egyptians, so much as emancipation. The Ten Plagues of Egypt have withered away from the story of the Exodus, and instead, the story depicts the Pharaoh as being a kind, even handed leader.
Due to the Egyptian Empire's long standing policy of religious tolerance, Jewish monuments such as the Temple of Solomon are intact. The Ark of the Covenant is not present, however, as it was taken by Arab invaders, and scrapped.
