The Collected Radical Addresses to the Unity Congregation (1888-1891) were originally given to Hugh O. Pentecost's Unity Congregation, which he started in 1887 after breaking with mainstream Christian denominations. The text of the addresses were subsequently published in Pentecost's journal, Twentieth Century, and are collected here for the first time. They concern social justice issues which are as pertinent today as they were in Pentecost's time: poverty, income inequality, the death penalty, education, and more. These addresses stand as important artifacts expressing the philosophies behind many of the radical reform movements of the late 19th-century, while still holding meaning for our current time. An introductory essay and extensive footnotes from editor Robert P. Helms add important context for these addresses.¿¿

Hugh Owen Pentecost (1848-1907) was an American minister, lawyer, and publisher. He espoused the single-tax theories of economist and social reformer Henry George, and was associated with socialist and anarchist political philosophies. While little known today, Pentecost was a well-known and controversial figure during his lifetime.
