had found the truth of evolution." Later in life, Carnegie's firm opposition to religion softened. For many years he was a member of Madison Avenue Presbyterian Church, pastored from 1905 to 1926 by Social Gospel exponent Henry Sloane Coffin, while his wife and daughter belonged to the Brick Presbyterian Church. He also prepared (but did not deliver) an address in which he professed a belief in "an Infinite and Eternal Energy from which all things proceed". Records exist of a short period of correspondence around 1912–1913 between Carnegie and 'Abdu'l-Bahá, the eldest son of Bahá'u'lláh, founder of the Baháʼí Faith. In these letters, one of which was published in The New York Times in full text, Carnegie is extolled as a "lover of the world of humanity and one of the founders of Universal Peace". World peace Influenced by his "favorite living hero in public life" John Bright, Carnegie started his efforts in pursuit of world peace at a young age, and supported causes that opposed military intervention. His motto, "All is well since all grows better", served not only as a good rationalization of his successful business career, but also his view of international relations. Despite his efforts towards international peace, Carnegie faced many dilemmas on his quest. These dilemmas are often regarded as conflicts between his view on international relations and his other loyalties. Throughout the 1880s and 1890s, for example, Carnegie allowed his steel works to fill large orders of armor plate for the building of an enlarged and modernized United States Navy, but he opposed American overseas expansion. Despite that, Carnegie served as a major donor for the newly-established International Court of Arbitration's Peace Palace – brainchild of Russian Tsar Nicolas II. His largest and in the long run most influential peace organization was the Carnegie Endowment for International Peace, formed in 1910 with a $10 million endowment. In 1913, at the dedication of the Peace Palace in The Hague, Carnegie predicted that the end of the war was as certain to come, and come soon, as day follows night. In 1914, on the eve of the First World War, Carnegie founded the Church Peace Union (CPU), a group of leaders in religion, academia, and politics. Through the CPU, Carnegie hoped to mobilize the world's churches, religious organizations, and other spiritual and moral resources to join in promoting moral leadership to put an end to war
