Shiite Islam shares many features with Christianity, such as a twelve-based structure, the last of whom is associated with Jesus, and self-flagellation rituals commemorating martyrdom.

Judged as of 2021-11. The claim is that Shiite Islam shares many features with Christianity, with the examples given: a twelve-based structure (Twelve Imams, as with the Twelve Apostles) whose last member (the Mahdi) is associated with Jesus, and self-flagellation rituals commemorating martyrdom (Ashura/Husayn, as with Christian flagellants and the Passion). True: scholarly sources confirm the features cited (Twelver Shiism's twelve Imams; the Mahdi's eschatological return together with Jesus; Ashura self-flagellation commemorating Husayn's martyrdom) and recognise parallels with Christianity. Mostly true: the features exist, but one example is overstated (e.g. the link between the Mahdi and Jesus is in eschatology, not identity). Mixed: about half of the cited parallels hold. Mostly false: the features are superficial or mischaracterised, with only one holding. False: none of the cited features exist.

   “According to the dominant Twelver Shi’a denomination, twelve imams—descendants of the Prophet—were the rightful rulers of the Muslim umma in its entirety.”

   “The Twelfth Imam was saved in order to eventually return as the Mahdi or the Guided One and, together with Jesus, “shall fill the earth with knowledge of God and justice.””

3. E3 Flagellation - Wikipedia Wikipedia · 5 November 2002

   “One school of Islam, Shi'ism, does or has practiced self-flagellation (tatbir) as a voluntary religious ritual where the faithful punish themselves (although sometimes symbolically), not for mortification of the flesh in the Christian manner, but in memory of the suffering and death of Hussein (Husayn ibn Ali), and for not helping the martyr in his final hours.”

4. E4 Mourning of Muharram - Wikipedia Wikipedia · 22 October 2007

   “Extreme forms of self-flagellation are also sometimes practiced, often involving self-inflicted bloodshed.”

E1 confirms that Twelver Shiism centres on twelve imams. E2 states that the Twelfth Imam will return as the Mahdi and, together with Jesus, fill the earth with justice. That supports the link to Jesus, though it is a shared role at the end of time, not identity. E3 and E4 confirm Shia self-flagellation in memory of Husayn's martyrdom. However, E3 says this differs from the Christian practice of mortification of the flesh, and none of the evidence explicitly calls these features parallels with Christianity. So the features exist, but the comparison is partly overstated.
