The Church and Science: A Historical Relationship

The relationship between the Catholic Church and science has been a topic of interest for centuries. While pop culture sometimes paints this relationship as a feud, a closer look at history shows a much richer, more nuanced story. The Catholic Church has been a supporter, sponsor, and sometimes even the initiator of scientific inquiry. In this article, we will explore this complex relationship, drawing from official teachings and historical examples.

The Foundation: Faith and Reason

Before delving into the historical relationship, it’s important to establish the Church’s view on faith and reason. According to the Catechism of the Catholic Church (CCC), “Though faith is above reason, there can never be any real discrepancy between faith and reason” (CCC 159). This makes it clear that the Church doesn’t see faith and reason as enemies. In fact, St. John Paul II wrote that faith and reason are like “two wings on which the human spirit rises to the contemplation of truth.”

The Bible also speaks to this, stating, “The heavens declare the glory of God; the skies proclaim the work of his hands” (Psalm 19:1). This suggests that understanding the natural world can be a way to understand God.

The Medieval Foundations of Science

Contrary to popular belief, the medieval period was not a “dark age” for science. Institutions like the University of Paris were established with the support of the Church, and they served as cradles for scientific study. Great Catholic thinkers like Albertus Magnus and Thomas Aquinas integrated the works of Aristotle and other ancient scholars into a Christian framework, laying the groundwork for modern science.

The Galileo Affair: A Misunderstanding

The case of Galileo Galilei is often cited as an example of the Church’s opposition to science. While it’s true that Galileo was tried and convicted of heresy, the conflict was not as black and white as it is often portrayed. Galileo’s ideas were not the problem; rather, it was the way he went about promoting them, sometimes contradicting Scripture in a manner that was considered inappropriate at the time.

The Church has since acknowledged its mistake. Pope John Paul II formally removed the ban against Galileo’s works in 1822, and in 1992, he acknowledged that the Church had erred in the way it handled the Galileo case.

Clergy Contributions to Science

Many are unaware that priests and other religious figures have made significant contributions to science. For example, Gregor Mendel, an Augustinian monk, is known as the father of genetics. Similarly, Georges Lemaître, a Belgian priest, was one of the founders of the theory of the Big Bang. These individuals saw no contradiction between their faith and their scientific pursuits.

Contemporary Church Teaching on Science

Today, the Church continues to support scientific efforts, particularly when they are aimed at alleviating human suffering or understanding the universe. Pope Francis, in his encyclical Laudato Si, speaks of the value of science in solving environmental problems, stating: “Science and religion, with their distinctive approaches to understanding reality, can enter into an intense dialogue fruitful for both.”

What’s the Catch? Ethical Boundaries

While the Church supports scientific inquiry, it also insists on ethical boundaries. The CCC states, “One must take into account the data of reason and faith, and the teaching authority of the Church to which they belong” (CCC 2294). Topics like embryonic stem cell research and certain practices in genetic engineering are areas where the Church calls for ethical discernment.


The historical relationship between the Catholic Church and science is one of collaboration, support, and at times, tension. However, the Church’s fundamental belief in the harmony between faith and reason allows for a respectful and fruitful interaction between these two fields. This relationship is rooted in the belief that by understanding the world around us, we can come closer to understanding God. It is not a relationship of contradiction but one of coexistence, guided by the pursuit of truth and the ethical dimensions of human life.
