Terms of Use
Last updated: October 18, 2026
These Terms of Use govern your use of latinmasspropers.com (the “Site”), operated by JY Concepts, based in New York, USA. By using the Site, you agree to these terms. If you don’t agree, please don’t use the Site.
What the Site offers
Latin Mass Propers is a free resource that shows the propers of the Masses of the 1962 Roman Missal in Latin, with the Epistle and Gospel in the Douay-Rheims English translation, and the calendar of when each Mass is said. We may change, add or remove features at any time.
The texts
The Latin texts and the 1962 calendar come from the Divinum Officium project (MIT licence), computed with Missale Meum (MIT licence). The English readings are the Douay-Rheims (Challoner) translation, in the public domain in the United States, from Project Gutenberg. The Site is not an official liturgical book and is not approved by any diocese, religious institute or society; for the Mass you attend, follow your priest and the books used in your church. We work to keep texts and dates accurate, but mistakes can happen; please report them.
