One of the central parallels is the idea of original sin. In Christianity, humanity’s fall began with a desire for forbidden knowledge, resulting in separation from God. Similarly, the Elric brothers commit the taboo of human transmutation, attempting to bring their mother back to life. Their punishment is immediate and devastating, reflecting the Christian concept that sin leads to suffering and spiritual loss. Edward loses his leg and then sacrifices his arm to save Alphonse’s soul, who in turn loses his entire body. This act echoes the biblical theme of consequence tied to disobedience.

The Homunculi, named after the seven deadly sins, serve as living embodiments of Christian moral failings. Lust, Gluttony, and Pride are not just characters, but reflections of humanity’s inner struggles. Their ultimate downfall reinforces the idea that succumbing to sin leads to destruction, a message consistent with Christian teachings.

Additionally, the pursuit of truth in Fullmetal Alchemist mirrors the Christian journey toward spiritual truth. Father, the primary antagonist, seeks godhood through manipulation and control, contrasting with characters like Hohenheim and Edward, who come to value humility and human connection.

Through its layered narrative, Fullmetal Alchemist offers a powerful exploration of Christian moral and spiritual themes, wrapped in a story of loss, love, and redemption.
