Opera Omnia Project

The Aquinas Institute is publishing the complete works of St. Thomas Aquinas. The goal is to have each work available in Latin and English in three formats: online, eBook and print.

The Latin-English bilingual edition will be 60 volumes, grouped in the following sets:

• Commentary on the Sentences (1-10)
• Summa Contra Gentiles (11-12)
• Summa Theologiae (13-22)
• Disputed Questions (23-29)
• Old Testament Commentaries (30-32)
• Gospel Commentaries (33-36)
• Pauline Commentaries (37-41)
• Catena Aurea (42-45)
• Commentaries on Aristotle (46-53)
• Other Commentaries (54)
• Opuscula (55-58)
• Historical Documents (59-60)

The five-year timeline for finishing the Latin-English edition follows. This timeline depends on raising the funds to get it done!
