Opera Omnia Project

Opera Omnia being printed

The writings of Saint Thomas Aquinas, recommended to our study for over 700 years by the Church’s Magisterium, are surprisingly difficult to acquire in high-quality editions that are not prohibitively priced. Moreover, certain works of the saint have never been published in English translation or in parallel Latin/English editions convenient for study. The Aquinas Institute is publishing the complete works of St. Thomas Aquinas in a Latin-English Bilingual Edition. The goal is to have each work available in Latin and English in three formats: online, eBook and print.

Help us Print the Opera Omnia

In order to keep the cost of the printed edition as low as possible, The Aquinas Institute needs the support of donors. All donations are tax-deductible, and donors may participate at various levels of giving. For donations of $5,000 or more, a personal dedication will be placed on the acknowledgements page of every work in the Opera Omnia series.
