Although the two doctrines of the trinity and the incarnation of God in Jesus Christ are the most fundamental doctrines of Christian theology, the Qur'an and Ahlul-Bayt's narratives have introduced them as blasphemy, and argued for their invalidity through different statements. Accordingly, the purpose and scope of the topic of this research has been determined to cover following issues: the explanation of the two doctrines of the trinity and incarnation in Christianity, their critique based on the Quran, the Shi'a narratives and some of the works of the Muslim scholars, and, finally, the analysis and critique of two doubts: " the difference between the trinity criticized by the Qur'an and the trinity believed by Christians” and "the similarity between incarnation in Christian theology and manifestation in Islamic sources". The research results indicate that the trinity and incarnation conflict with some definite principles of monotheism, and have many flaws including contradiction, the combinability of the essence of God, the defect of the attributes of perfection in the three essences, change and passivity in the essence of God.
