Lamb of God portrays same-sex relationships almost exclusively through the lens of child sexual abuse and exploitation. The narrative depicts young boys as victims and older men as perpetrators, resulting in a deeply problematic and negative portrayal that associates same-sex interactions with trauma and degradation.

The film uses Christian symbolism, particularly the 'Lamb of God' motif, to explore themes of innocence, corruption, and abuse within a religiously-tinged environment. The narrative critiques the hypocrisy and darker aspects associated with certain religious interpretations or institutions, portraying them as complicit in or enabling harm.
