It is not failed and no it is not the strongest engine for atheism. The strongest engine for atheism is not believing in God.
Episcopal Church, General Convention (2006)
Resolved, That the 75th General Convention affirm that God is Creator, in accordance with the witness of Scripture and the ancient Creeds of the Church; and be it further,
Resolved, That the theory of evolution provides a fruitful and unifying scientific explanation for the emergence of life on earth, that many theological interpretations of origins can readily embrace an evolutionary outlook, and that an acceptance of evolution is entirely compatible with an authentic and living Christian faith; and be it further
Resolved, That Episcopalians strongly encourage state legislatures and state and local boards of education to establish standards for science education based on the best available scientific knowledge as accepted by a consensus of the scientific community; and be it further
Resolved, That Episcopal dioceses and congregations seek the assistance of scientists and science educators in understanding what constitutes reliable scientific knowledge.
Central Conference of American Rabbis
Whereas the principles and concepts of biological evolution are basic to understanding science; and
Whereas students who are not taught these principles, or who hear "creationism" presented as a scientific alternative, will not be receiving an education based on modern scientific knowledge; and
Whereas these students' ignorance about evolution will seriously undermine their understanding of the world and the natural laws governing it, and their introduction to other explanations described as "scientific" will give them false ideas about scientific methods and criteria,
Be it resolved that we call upon publishers of science textbooks to reject those texts that clearly distort the integrity of science and to treat other explanations of human origins for just what they are — beyond the realm of science;
Be it further resolved that we call upon science teachers and local school authorities in all states to demand quality textbooks that are based on modern, scientific knowledge and that exclude "scientific" creationism;
Be it further resolved that we call upon parents and other citizens concerned about the quality of science education in the public schools to urge their Boards of Education, publishers, and science teachers to implement these needed reforms.
General Assembly of the Presbyterian Church (USA)
The 214th General Assembly of the Presbyterian Church (USA):
1. Reaffirms that God is Creator, in accordance with the witness of Scripture and The Reformed Confessions.
2. Reaffirms that there is no contradiction between an evolutionary theory of human origins and the doctrine of God as Creator.
3. Encourages State Boards of Education across the nation to establish standards for science education in public schools based on the most reliable content of scientific knowledge as determined by the scientific community.
4. Calls upon Presbyterian scientists and science educators to assist congregations, presbyteries, communities, and the public to understand what constitutes reliable scientific knowledge.
Since the publication of Charles Darwin's On the Origin of Species in 1859, the attitude of the Catholic Church on the theory of evolution has slowly been refined. Early contributions to the development of evolutionary theory were made by Catholic scientists such as Jean-Baptiste Lamarck and the Augustinian monk Gregor Mendel.
For nearly a century, the papacy offered no authoritative pronouncement on Darwin's theories. In the 1950 encyclical Humani generis, Pope Pius XII confirmed that there is no intrinsic conflict between Christianity and the theory of evolution, provided that Christians believe that the individual soul is a direct creation by God and not the product of purely material forces. Today, the Church supports theistic evolution(ism), also known as evolutionary creation, although Catholics are free not to believe in any part of evolutionary theory.
According to Eugenie Scott, Director of the US National Center for Science Education: "Theistic evolutionism" is the official position of the Catholic church. In 1996, Pope John Paul II reiterated the Catholic TE position, according to which God created, evolution occurred, human beings may indeed have been descended from more primitive forms, and the Hand of God was required for the production of the human soul". Statements from the Church in recent decades hold that faith and scientific findings regarding human evolution are not in conflict, though humans are regarded as a special creation, and that the existence of God is required to explain both monogenism and the spiritual component of human origins. Moreover, the Church teaches that the process of evolution is a planned and purpose-driven natural process, guided by God.
