The Congregation of the Most Holy Redeemer (Latin: Congregatio Sanctissimi Redemptoris – C.Ss.R) is a Roman Catholic missionary congregation founded by Saint Alphonsus Liguori at Scala, near Amalfi, Italy, for the purpose of labouring among the neglected country people in the neighbourhood of Naples.
Members of the Congregation, Catholic priests, and consecrated religious brothers, are known as Redemptorists, who are often associated with the image of Our Mother of Perpetual Help and globally minister in more than 82 countries around the world.
