Father Roman Hoppe was a Polish priest and author of the twentieth century. His small booklet on The Two Divine Promises details a Polish devotion which originated with revelations in 1954 and is now spread worldwide. He made use of the sacraments as well as prayer in order to explain its unique method for growth in holiness. Father Hoppe originally published the work in 1954 through San Miguel Publishing Company, Michigan. The Two Divine Promises was retypeset by TAN in 1987.
