Dr. Robert S. Bilheimer (September 28, 1917 – December 17, 2006) was an American Presbyterian theologian.
[1][2] In his 1947 book What Must the Church Do?, he used the phrase "New Reformation" to refer to the ecumenical movement that resulted from the 1910 World Missionary Conference, and this usage became commonplace thereafter.
[4] He later gave credit for most of the founding of the organization to the laity and young people.
[5] From 1955 to 1958, he co-chaired a WCC international commission to prepare a document addressing the threat of nuclear warfare during the Cold War.
[6] As a WCC delegate, he prepared the Cottesloe Consultation, which took place in December 1960 and saw the WCC meet with representatives from the eight main Christian denominations in South Africa in order to address the issue of apartheid.
