Short answer: No. Jainism does not support or promote a birth-based caste system for spiritual life or moral worth.

Key points:

• The path to liberation (moksha) in Jainism is about one’s karma and personal conduct, not birth or social status. All jivas (souls) are considered equal in their potential for right faith, right knowledge, and right conduct.
• Caste or varna distinctions are social phenomena, not religious prerequisites in Jain practice. Jain monks and lay followers come from diverse backgrounds, and distribution of duties or prestige in Jain communities is not framed as a religious hierarchy.
• Jain scriptures emphasize non-violence, truth, non-attachment, and equality before the Dharma. Any notion that a person’s birth determines their spiritual worth goes against this fundamental teaching.
• There are differences between Digambaras and Śvetāmbaras on many ritual and doctrinal points, but neither tradition uses caste as a basis for spiritual eligibility or merit.

If you’d like, I can provide a simple quote from Jain texts that reflects this emphasis on equality and karma over birth.
