Matthew offers a range of courses, including introductory and intermediate Latin, classical and koine (New Testament) Greek, entirely online.
The Introductory New Testament Greek course is the ideal preparation for the Latin Mass Society’s residential course above, at which Mr Spencer will be the Greek tutor.
Seminarians and clergy can claim half the cost of Latin courses with Mr Spencer back from the Latin Mass Society.
For his current offerings, see this pdf.
This is also highly recommended, though not associated with the Latin Mass Society. See her website here
