"When thought dwells in God, — and it should not, to our consciousness, dwell elsewhere, — one must benefit those who hold a place in one’s memory, whether it be friend or foe, and each share the benefit of that radiation."
-Mary Baker Eddy

Mary Baker Eddy prayed daily for world peace. And there’s a story behind this flag, which she received in 1907. She gifted it for safekeeping to her church.

This “peace flag” is currently displayed on the second floor wall of The Christian Science Publishing House in Boston. Representative of the hopefulness and enthusiasm that characterized many of the pre-World War I peace movements in America, the earliest peace flags date back to 1891.

In 1898 Eddy wrote: “I earnestly request that all true Christian Scientists in our land, or in foreign lands - whether taught by me personally or through my books -- will unite in prayer for peace: For the end of hostility and war among or between all nations, and religious sects,— for divine Love to make us one human family, to have one Father-Mother God, one Christ, whereof the Scriptures bear witness; and to demonstrate the divine Life, Truth, and Love– healing the sick, blessing our enemies, and all mankind.” (A10200)

NEW: Mary Baker Eddy includes an allegory of a fictional courtroom scene in her chapter “Christian Science Practice” in Science and Health. The trial includes over 20 characters in a 13-page section of the chapter, illustrating what Eddy termed “a mental court case.”

When was the trial allegory first written? Did it change over time as Eddy made other clarifying edits to Science and Health? Enjoy our recent “Ask a Researcher” article, which answers these questions and more.
