(most famously the Scopes Trial), during this period Great Britain experienced a concerted effort at reconciliation, championed by intellectually conservative scientists, supported by liberal theologians but opposed by younger scientists and secularists and conservative Christians. These attempts at reconciliation fell apart in the 1930s due to increased social tensions, moves towards neo-orthodox theology and the acceptance of the modern evolutionary synthesis. In the 20th century, several ecumenical organizations promoting a harmony between science and Christianity were founded, most notably the American Scientific Affiliation, The Biologos Foundation, Christians in Science, The Society of Ordained Scientists, and The Veritas Forum. Branches of Christianity Catholicism While refined and clarified over the centuries, the Catholic position on the relationship between science and religion is one of harmony, and has maintained the teaching of natural law as set forth by Thomas Aquinas. For example, regarding scientific study such as that of evolution, the church's unofficial position is an example of theistic evolution, stating 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.

Galileo once stated "The intention of the Holy Spirit is to teach us how to go to heaven, not how the heavens go." In 1981, John Paul II, then pope of the Catholic Church, spoke of the relationship this way: "The Bible itself speaks to us of the origin of the universe and its make-up, not in order to provide us with a scientific treatise, but in order to state the correct relationships of Man with God and with the universe. Sacred Scripture wishes simply to declare that the world was created by God, and in order to teach this truth it expresses itself in the terms of the cosmology in use at the time of the writer". The influence of the Church on Western letters and learning has been formidable. The ancient texts of the Bible have deeply influenced Western art, literature and culture. For centuries following the collapse of the Western Roman Empire, small monastic communities were practically the only outposts of literacy in Western Europe. In time, the Cathedral schools developed into Europe's earliest universities and the church has established thousands of primary, secondary and
