Pope Francis鈥� recent statement at the Pontifical Academy of Science that evolution and the Big Bang model are not contrary to Catholic beliefs created quite a stir. Afterall, for many people the notion that the Church is anti- science is a given. And they have many examples to support their opinion. Galileo was put under house arrest for claiming that the Sun and not the Earth was the center of our planetary system. Giordano Bruno, who was burned at the stake for his free-thinking ideas, is considered today to be a martyr to science.
However, the position of the Catholic Church on current scientific issues is much more in line with the scientific consensus. Many US Protestant denominations believe in a world created by God in its present form less than 10,000 years ago. This is a view shared by 40% of Americans according to a 2014 Gallup survey. In contrast, the Catholic Church has had a much more open attitude toward evolution.
For the first 100 years or so after the 1859 publication of Charles Darwin's聽On the Origin of Species聽the Church did not take an official position (although local clergy tended to be hostile). This allowed for a relatively open discussion of the topic among catholic scholars. It led Pope Pius XII, in the 1950 Encyclical聽Human generis, to accept evolution as a聽possibility聽(as opposed to a聽probability) which warranted further studies. Subsequently Pope John Paul II declared in 1996 in a pronouncement to the Pontifical Academy of Science that Evolution is "more than a hypothesis." It is interesting to note in this light, that before Darwin, the French Jesuit, Jean Baptiste Lamarck (1744-1829), was the first to postulate that species could develop new traits as needed for their survival and that these traits could be passed on to their offspring. And when it comes to the Big Bang it was first proposed by the Belgian priest Georges Lemaitre who himself was president of the Pontifical Academy of Science.
The Pontifical Academy of Sciences was established in 1936 by Pope Pius XI to advise the Pope on scientific matters. Its membership consists of 80 members and includes numerous Nobel Prize winners including Canadian John Polanyi and Israeli Aaron Ciechanover. The current president is Werner Arber, 1978 Nobel laureate, for his work on recombinant DNA technology. Werner Arber is the first Protestant to hold that position. The Academy does not shy away from controversial issues. In 2009 a group of its members, led by Werner Arber, released a statement praising GMOs as a useful tool to help the world's poor. The statement takes issues with objections made by critics and states that their misguided opposition prevents, or slows, the development of crops for the public good, especially in Third World countries.
The Pope, who has a scientific background with a master in chemistry, has come strongly in favor of sustainable development. In a recent address he has argued for the "respect of the beauty of nature." In his speech he stressed the need to "Safeguard Creation because if we destroy Creation, Creation will destroy us."
The openness of the Church does not extend to what it considers to be moral or ethical issues. It is widely accepted that the use of condoms is the most reliable way, outside the unrealistic abstinence method promoted by the Church, to prevent the spread of AIDS. Still when Pope John II visited Tanzania, a country where AIDS is rampant, he declared that condoms were a sin in any circumstances.聽聽It should be interesting to see if the Catholic Church under Pope Francis will evolve on this issue as well.
