Just a quick note about The Sapientis Institute. I cannot say I know a great deal about this particular Institute, but their offerings looked of interest.
They offer online-based learning specifically focused in the area of Aristotelian-Thomistic philosophy. While that is interesting enough in its own right, what I wished to draw our readers attention to is the fact that this institute also offers online courses in Ecclesiastical Latin. (See Beginning Latin 1A and Beginning Latin 1B. Apparently, further Latin courses are planned.)
The cost per course is $250.00 USD per household, with three month payment plans offered.
Clergy, religious and seminarians will be particularly interested to know that some of this Institute's courses are offered free to them. Sadly, this does not include the Latin courses, though a limited number of free spots are made available.
