John A. (John Augustine) Ryan

John Augustine Ryan (1869–1945) was an American Catholic priest who was a noted moral theologian and advocate of social justice. Ryan lived during a decisive moment in the development of Catholic social teaching within the United States. The largest influx of immigrants in America's history, the emancipation of American slaves, and the Industrial Revolution had produced a new social climate in the early twentieth century, and the Catholic Church faced increasing pressure to take a stance on questions of social reform.
