St. Alphonsus Liguori is the founder of the Congregation of the Most Holy Redeemer, better known as the Redemptorists.
The Sons of the Most Holy Redeemer are exclusively Latin/Mass in the Extraordinary Form (MEF).
There is also a cloistered female counterpart, known as the Order of the Most Holy Redeemer, or the Redemptoristines.
My organization built an unofficial website for the Redemptoristines in Australia:
This particular monastery had been in danger of suppression, but the Holy See asked another Redemptoristine to go to Australia and be novice mistress to the five or six who were seeking admission.
Please pray for vocations to both branches!
