After traveling through Europe in 1947—including to Scotland, Amsterdam, and Switzerland—Reinhold Niebuhr wrote some reflections, including on state churches, the Truman Doctrine, Christian political parties, and more.
Recognizing the place for a genuine religious hope born of faith and for an enthusiasm for realization of social and ethical gains in any historical situation, Christianity will nevertheless, when true to itself, set its face against utopianism or popular brands of optimism.
At the end of Reinhold Niebuhr’s travels across Western Europe in 1947, he spent a week at the Ecumenical Institute, a facility near Geneva. He was hopeful of how this project would bless the church life of the world, and he offered observations about discussions there about communism, church-state relations, Christian political parties, and more.
During an address to the US Congress on March 12, 1947, President Harry Truman called for military and economic aid to Turkey and Greece to counter communist threats. This began the Truman Doctrine, and Christian realists responded a month later.
