The Congregation of the Sons of the Most Holy Redeemer, commonly known as the Transalpine Redemptorists or The Sons, are a religious institute of the Catholic Church canonically erected in the Roman Catholic Diocese of Aberdeen and based on Papa Stronsay in the Orkney Islands, Scotland, as well as in the city of Christchurch, New Zealand. They were formed in 1988 as a traditionalist offshoot of the Redemptorists, following a monastic rule based on that of Alphonsus Liguori, and was later formally erected as a religious institute in 2012.
