Who We Are

The Congregation of Marian Fathers of the Immaculate Conception of the Most Blessed Virgin Mary is a fraternal community of consecrated life in the Roman Catholic Church. In America, the members of the Congregation are perhaps best known for their work promoting the message of Divine Mercy from the National Shrine of The Divine Mercy in Stockbridge, Massachusetts. They are also known for their devotion to Mary Immaculate, dedication to praying for the poor souls in Purgatory, and active service to the Church.

Founded in Poland in 1670 by St. Stanislaus Papczynski, today the Marian Congregation has well over 500 priests and brothers who labor in 20 countries, including: the USA, Argentina, Australia, Belarus, Brazil, Cameroon, Czech Republic, Germany, Italy, Kazakhstan, Latvia, Lithuania, Philippines, Poland, Portugal, Rwanda, Ukraine, and the United Kingdom.

The Marian Congregation is unique in that it has not only a founder, St. Stanislaus, but also what the Marians call a "Renovator": Lithuanian-born Blessed George Matulaitis, who saved and refounded the Order in 1910, unleashing a zealous army for Christ and the Church in the modern world.

The Marian Fathers are the publishers of St. Faustina’s diary, Divine Mercy in My Soul, in many languages. Our printing presses produce some 50 million pieces of literature and images a year all sent out to a world yearning for meaning, mercy, and healing. We administer the National Shrine of The Divine Mercy, which receives tens of thousands of visitors a year who seek spiritual renewal through the sacraments.

Inspired by the Great Mercy Pope, St. John Paul II, enroll in our spiritual benefit society, the Association of Marian Helpers, and help us in our task to make it known that, in the words of Jesus to St. Faustina, “Mankind will not have peace until it turns with trust to My Mercy” (Diary, 300).
