Judaism, Christianity and Islam share belief in one creator God and divine judgment of human conduct. The Bahá'í Faith also teaches one creator God and spiritual accountability, but these religions differ in how they understand judgment and humanity's ultimate destination.
Monotheism means belief in one God. In these traditions, belief in a creator connects human life with moral responsibility: adherents understand their actions as accountable to God. However, shared concepts do not imply identical teachings about salvation or the afterlife.
| Religion | One creator God | Judgment and ultimate destination |
|---|---|---|
| Judaism | God is the sole creator; the Shema, a central declaration of faith, affirms God's oneness. | Divine judgment is significant, particularly during Rosh Hashanah and Yom Kippur. Jewish traditions emphasize responsibility in this life, with diverse understandings of Olam Ha-Ba, the world to come. |
| Christianity | Most Christians understand one God through the Trinity, Father, Son and Holy Spirit. | Judgment is linked to resurrection and eternal life. Heaven and hell are widely taught; Roman Catholic teaching also includes purgatory, purification for those destined for heaven. |
| Islam | Tawhid, the oneness of Allah, excludes any partner or equal to Allah. | Yawm al-din, the Day of Judgment, involves accountability before Allah and is connected with paradise and hell. |
| Bahá'í Faith | One God creates humanity and guides it through successive manifestations of God. | Paradise and hell describe spiritual states of closeness to or distance from God, rather than physical places. |
The misconception that all monotheistic religions teach the same judgment and afterlife must be corrected. Orthodox Judaism generally expects a personal human Messiah, while many Reform interpretations emphasize a Messianic age of peace and justice; neither should be treated as identical to Christian or Islamic teachings.
For IB Part 1, connect this comparison to “Where are we going?” In a Paper 1 Explain response, develop the belief-to-practice link, such as divine accountability encouraging repentance, and relate it to the stimulus.
