Handbook of Evolutionary Thinking in the Sciences. Dordrecht: Springer. pp. 881, 884. ISBN9789401790147. Creationism is not a single homogenous doctrine ... Evolution, as a process, is a tool God uses to continually create the world. Here we have arrived at another sub-category of creationism called 'evolutionist creationism'
^Haarsma 2010, p. 168, "Some Christians, often called 'Young Earth creationists,' reject evolution in order to maintain a semi-literal interpretation of certain biblical passages. Other Christians, called 'progressive creationists,' accept the scientific evidence for some evolution over a long history of the earth, but also insist that God must have performed some miracles during that history to create new life-forms. Intelligent design, as it is promoted in North America is a form of progressive creation. Still other Christians, called theistic evolutionists' or 'evolutionary creationists,' assert that the scientific theory of evolution and the religious beliefs of Christianity can both be true."
^Numbers 1998, p. 50 "Since at least the early 1840s Darwin had occasionally referred to 'creationists' in his unpublished writings, but the epithet acquired little public currency." – sketch written in 1842 – "if this had happened on an island, whence could the new forms have come,—here the geologist calls in creationists."
