PARIS — The Rev. Peter Richardson will be the speaker at 10 a.m. Sunday, May 21, at the First Universalist Church on Pine Street.

Richardson’s topic will be “Universalism on the Frontier.” Universalism was a product of frontier days in northern New England. Maine’s first organized Universalist congregation was convened in Norway and Paris. One of those founders, General Levi Hubbard of Paris, names Oxford County after his home town, Oxford, Massachusetts.

With degrees from Tufts and St. Lawrence universities, both founded by the Universalists, Richardson was ordained to the ministry of religion in 1965 by the First Universalist Church of Kent, Ohio. He also served congregations in Texas, Massachusetts and Kennebunk, Maine.

He is the author of six books of history, psychological type and spirituality, religious philosophy, poetry and of a forthcoming work, “Universalists and Unitarians of Maine,” due to be released midsummer. He has traveled to pilgrimages to more than 20 countries, using his photography in his writings and ministry and conducting workshops in four countries and 13 U.S. states.

All are welcome. The church is handicapped accessible.

Members of the West Paris Universalist Church will attend the service.
