Comments about the relationship between Science and Faith in the  
Magisterium of the Church*  
Reyber Parra Contreras **  
ABSTRACT  
The text analyzes the relationship between Science and Faith in the Magisterium of the  
Catholic Church. The analysis is based on the position of the Vatican Councils I and II about  
the importance of Faith and Reason for man, in his search for truth; simultaneously, the  
orientations of popes Leo XIII and John Paul II were taken into account, in their Encyclicals  
Aeterni Patris and Fides et Ratio, respectively; some speeches by Popes Paul VI, Benedict  
XVI and Francis before the Pontifical Academy of Sciences were also analyzed. The Church  
has sought - from the First Vatican Council to the present - to bring, harmonize and  
complement the relationship between Faith and Reason; its interest is not limited to  
promoting scientific research; it also aspires that knowledge be ordered to the welfare of the  
human being, and the horizon of faith is recognized in the search for truth.  
KEY WORDS: Church; Science; Faith; Philosophy.

Comentarios acerca de la relación entre Ciencia y Fe en el Magisterio  
de la Iglesia  
RESUMEN  
En el texto se analiza la relación entre Ciencia y Fe en el Magisterio de la Iglesia Católica.  
El análisis se fundamenta en la posición de los Concilios Vaticano I y II sobre la importancia  
de la Fe y la Razón para el hombre, en su búsqueda de la verdad; simultáneamente, se  
tomaron en cuenta las orientaciones de los papas León XIII y Juan Pablo II, en sus  
Encíclicas Aeterni Patris y Fides et Ratio, respectivamente; también fueron analizados  
algunos discursos de los papas Pablo VI, Benedicto XVI y Francisco ante la Pontificia  
Academia de las Ciencias. La Iglesia ha procurado -desde el Concilio Vaticano I hasta la  
actualidad-, acercar, armonizar y complementar la relación entre Fe y Razón; su interés no  
se agota en el fomento de la investigación científica; también aspira que el conocimiento se  
ordene al bienestar del ser humano, y se reconozca el horizonte de la fe en la búsqueda de  
la verdad.  
PALABRAS CLAVE: Iglesia; Ciencia; Fe; Filosofía.  
In the course of Modernity, the Church had to resist and at the same time give  
response to the secularization of the West, a conflict that in fact resulted in an order based  
on the primacy of the individual and the reason, contrary to Christian identity. of that world  
in which, progressively, was ignoring the principle of authority of the Church. Various events  
with a certain degree of interrelation, favored the introduction of secularism, among them:  
the Protestant reform, the revolutionary anticlericalism of the 18th century and the “rationalist  
exacerbation or secularization of logos (Rivas García, 2013). This last aspect raised a  
distance between Christian Philosophy (Aristotelian scholasticism) and modern science  
(
marked by the experimental method).  
As a consequence of its positive evaluation of human reason -in its artistic and  
scientific expressions-, the Church tried in the 19th century to reduce the gap that had been  
interposed between the fields of metaphysical and phenomenal knowledge. The First  
Vatican Council, through the Dogmatic Constitution Dei Filius (April 24, 1870), laid the  
doctrinal and pastoral foundations in order to seek the convergence between Faith and

Reason, an aspiration that has been relevant in the Magisterium since then and up to the  
present.  
The council fathers recognized a double order of knowledge that, although different,  
have in common the search for the truth. This latter, as a metaphysical notion, cannot be  
fully encompassed by Science, whose object is the sensible world. Consequently, it requires  
the help of the Faith for its full development. Both are understood as gifts that God grants to  
man, and therefore they cannot disagree with each other, or contradict each other; both are  
important and their healthy orientation consists in helping each other in the task of knowing,  
thus man, when proceeding from the primary Being that is Truth, longs for their knowledge.  
Although the Council gives Faith primacy over Reason (in tune with the teachings of Saint  
Thomas Aquinas), it declares that the arts and scientific disciplines come from God, and  
recognizes the importance of the principles and methods that govern them.  
In accordance with the guidelines of the Vatican Council I, Pope Leo XIII in his  
Encyclical Aeterni Patris (August 4, 1879), distinguishes and claims the qualities and rights  
of both forms of knowledge, maintaining that Faith is for human Reason, the star that  
indicates the place of the port of truth. At the same time, the pope considers fair to recognize  
the proper scope of both, without confusing them; this does not prevent that, following the  
example of Saint Thomas Aquinas, both are "friendly associated", with the purpose of  
producing the benefit of knowledge. On the side of Faith, for its understanding and study,  
Leo XIII proposes to guide theological research through the principles of the Aristotelian  
scholasticism of Saint Thomas Aquinas; regarding Science, the Pope reiterates that the light  
of reason comes from God and, therefore, neither the Church nor Christian Philosophy can  
be contrary to the development of scientific research.  
Late in the 20th century, the Second Vatican Council, through the Pastoral  
Constitution Gaudium et Spes (December 7, 1965), reaffirmed the teachings transmitted by  
the first Vatican Council regarding the importance of Science to bring man closer to the truth,  
although by itself the capacity to find the full truth is not recognized. It is inconvenient - the  
Council warns - that man trusts excessively in Reason, to the point of believing himself self-  
sufficient and independent of God.  
Pope Paul VI, based on the reflections of the Council, alluded to the transcendental  
content that underlies in the field of study of Science, and insisted that it cannot by itself fully

explain it, so it must be open to the philosophical explanation: “How many stars in the sky!  
Certain. But how and why? How wonderful in the anatomy and physiology of the human  
body! Undoubtedly. But what is the human body for? For what man? Here science remains  
mute, and must be, at the risk of leaving its own domain” (Paul VI, April 23, 1966).  
More recently, Pope John Paul II (September 14, 1998) promulgated the Encyclical  
Fides et Ratio, where in poetic form he pointed out that “faith and reason are like the two  
wings with which the human spirit rises towards the contemplation of the truth". There should  
be no competition between the two, since both can help each other in the search for truth,  
without each losing its own space for realization: the transcendent, on the one hand; and the  
phenomenal, on the other. Faith can illuminate Reason, with which it is possible to reach the  
deep meaning of each thing. Therefore, Pope John Paul II advocates the development of a  
Philosophy of metaphysical scope, which is not limited to the phenomenal.  
This last approach is taken up by Pope Benedict XVI (October 28, 2010), who  
proposes an interdisciplinary relationship between Science and philosophical reflection, in  
order to help scientists discover the epistemological foundation of their methodology. In  
addition, this conjunction would also contribute to address the limitation of Science, in that it  
cannot by itself "explain everything and satisfy the spiritual needs of man" (Benedict XVI,  
November 6, 2006). However, although Science is incapable of replacing Faith, also in terms  
of Reason it comes from God (First Being), who assigns an order to its creation (the great  
book of nature, according to Paul VI), which makes it possible its intelligibility and, therefore,  
its study through the scientific method. In fact, Science is a "patient and passionate search  
for the truth about the cosmos, nature and the constitution of the human being" (Benedict  
XVI, October 28, 2010).  
In both Pope Benedict XVI and his successor Pope Francisco, Science must be  
guided by an ethic that joins it with the principles of fraternity and peace: “The scientific  
community is called to serve the human family and its integral development (Francisco,  
November 12, 2018). This ethical position is anthropocentric: “Science does not exist except  
by and for man; it has to leave the circle of his research and lead to man, and through him  
to society and to the whole history(Paul VI, April 23, 1966). However, when Faith enlightens  
Science, then it is able to rise and contribute knowledge in charity ("charity of knowledge",  
Paul VI would affirm). A distinctive feature of the charitable ideal of Science, it is expressed

by Pope Francisco in the following terms: “How nice it would be if as we discover new distant  
planets, we rediscover the needs of the brother or sister in orbit around me" (Francisco,  
October 7, 2020).  
Therefore, the Church has procured- from the First Vatican Council to the present - to  
bring closer, harmonize and complement the relationship between Faith and Reason, so  
man can "adequately know himself, the world and God" (John Paul II, September 14, 1998).  
In this sense, the Church's interest is not limited to promoting scientific research; It also  
aspires that knowledge be ordered to the welfare of the human being, and the horizon of  
faith is recognized in the search for truth.  
The Church's proposal for a dialogue between Faith and Reason has been developing  
despite the differences between the two ways of reaching knowledge; this purpose has  
influenced the zeal favorably with which the Church itself has lavished attentions on these  
two roads that man travels in his search for truth. The political and economic leaders in the  
world who have the responsibility of leading the attention of the great current challenges of  
humanity -among which the preservation of life on our planet and the fraternal coexistence  
among peoples stand out-, can find in this dialogical attitude of the Church a testimony about  
the possibility of approaching positions despite differences, without the parts deny of their  
principles or renounce to their convictions.
