Jesus in the Talmud
In the first few centuries CE, there were many sects of Judaism (such as Pharisees, Essenes, and Sadducees) each claiming to be the correct faith. Some scholars treat Christianity, during that era, referred to as Early Christianity, as simply one of many sects of Judaism. Some sects wrote polemics advocating their position, and occasionally disparaging rival sects. Some scholars view the depictions of Jesus in the Talmud as a manifestation of those inter-sect rivalries – thus the depictions can be read as polemics by the rabbinic authors of the Talmud which indirectly criticized the rival sect (Christianity), which was growing and becoming more dominant.
Islamic schools and branches
In addition to these two main branches, many other opinions also formed regarding succession to Muhammad. The first centuries of Islam gave rise to three major sects: Sunnis, Shi'as and Kharijites. Each sect developed distinct jurisprudence schools ("madhhab") reflecting different methodologies of jurisprudence ("fiqh"). The major Sunni madhhabs are Hanafi, Maliki, Shafi'i, and Hanbali. The major Shi'a branches are Twelver (Imami), Ismaili (Sevener) and Zaidi (Fiver). Isma'ilism later split into Nizari Ismaili and Musta’li Ismaili, and then Mustaali was divided into Hafizi and Taiyabi Ismailis. It also gave rise to the Qarmatian movement and the Druze faith. Twelver Shiism developed Ja'fari jurisprudence whose branches are Akhbarism and Usulism, and other movements such as Alawites, Shaykism and Alevism. Similarly, Kharijites were initially divided into five major branches: Sufris, Azariqa, Najdat, Adjarites and Ibadis. Among these numerous branches, only Hanafi, Maliki, Shafi'i, Hanbali, Imamiyyah-Ja'fari-Usuli, Nizārī Ismā'īlī, Alevi, Zaydi, Ibadi, Zahiri, Alawite, Druze and Taiyabi communities have survived. In addition, new schools of thought and movements like Quranist Muslims, Ahmadi Muslims and African American Muslims later emerged independently.
