The main theological differences between Śvetāmbars and Digāmbars are based on scripture authority, monastic practice, and some doctrinal beliefs. Both follow Jain Dharma and share core principles like ahiṃsā, karma, moksha, and the Tīrthaṅkaras.

1. Clothing of monks and nuns

• Śvetāmbars: Monks and nuns wear white clothing.
• Digāmbars: True monks practice nakedness as a sign of complete renunciation.

2. Ability of women to attain liberation

• Śvetāmbars: Believe women can attain moksha in female body.
• Digāmbars: Traditionally believe women must first be reborn as men to attain moksha.

3. Liberation of Lord Mahāvīra

• Śvetāmbars: Teach that Mahāvīra was born as a prince and later attained omniscience, but their textual tradition describes some details differently from Digāmbar tradition.
• Digāmbars: Hold that a Tīrthaṅkara such as Mahāvīra does not eat, speak, or act in ordinary bodily ways after renunciation in the same manner described in some Śvetāmbar texts.

4. Can a Tīrthaṅkara marry and have children?

• Śvetāmbars: Generally accept that Tīrthaṅkaras like Mahāvīra married and had a daughter.
• Digāmbars: Generally reject this and say Tīrthaṅkaras renounce very early and do not marry.

5. Scriptures accepted

• Śvetāmbars: Accept the Āgamas as authoritative scriptures.
• Digāmbars: Believe the original Āgamas were lost, and rely on other canonical texts like Ṣaṭkhaṇḍāgama, Kaṣāyapāhuḍa, and later works.

6. Status of omniscience

• Śvetāmbars: Usually hold that kevalajñāna can arise while the Tīrthaṅkara still performs activities in the world.
• Digāmbars: Emphasize a more strict separation of the liberated soul from bodily activities.

7. Image worship and temple tradition

• Both traditions do pūjā and temple worship, but:

- Śvetāmbars use more ornamented idols and rituals in many subtraditions. - Digāmbars prefer simpler, unclothed images of the Jina.

8. Sub-sects and ritual differences

• Śvetāmbars include subgroups like:

- Mūrtipūjak - Sthānakavāsī - Terāpanth

• Digāmbar tradition also has multiple monastic and ritual lineages.

In short

The deepest theological differences are mainly:

• nudity vs white clothing
• women’s capacity for liberation
• scriptural authority
• biographical interpretation of Tīrthaṅkaras

Yet both traditions remain firmly Jain and share the same spiritual goal: liberation of the soul through right faith, right knowledge, and right conduct.

If you want, I can also give this in a simple comparison table.
