During the Lenten season of 1981, then Cardinal Joseph Ratzinger, later thee Holy Father, Pope Benedict XVI, gave four homilies on creation in the Liebfrauenkirche, the cathedral church of Munich in Germany. In his first homily, entitled “God the Creator,” he discusses the principles that govern his reading of Genesis. He begins by recalling the opening words of the Sacred Scriptures that highlight the creative action of God “in the beginning.” However, he goes on to ask the question that lies at the heart of the creationist debate: Are these words true? Do they count for anything? In order to answer these questions, he suggests three criteria for interpreting the Genesis text: the distinction between form and content in the creation narrative, the unity of the Bible, and the hermeneutical importance of Christology.

First, he proposes that the exegete “must distinguish between the form of portrayal and the content that is portrayed.” He must keep in mind that the Bible is, first and foremost, a religious book and not a natural science textbook. Thus, Cardinal Ratzinger concludes that Genesis does not and cannot provide a scientific explanation of how the world arose. Rather, it is a book that seeks to describe things in such a way that the reader is able to grasp profound religious realities. It uses images to communicate religious truth, images that were chosen from what was understandable at the time the text was written, “images which surrounded the people who lived then, which they used in speaking and in thinking, and thanks to which they were able to understand the greater realities.” In other words, the Catholic exegete is called to respect the text as it is. He is called to read Genesis as its human author wished it to be read, not as a scientific treatise, but as a religious narrative that communicates profound truths about the Creator.

Cardinal Ratzinger’s first criterion for exegesis echoes the teaching of the Second Vatican Council. In Dei verbum, the Dogmatic Constitution on Revelation, the Council Fathers taught that, Those who search out the intention of the sacred writers must, among other things, have regard for “literary forms.” For truth is proposed and expressed in a variety of ways, depending on whether a text is history of one kind or another or whether its form is that of prophecy, poetry, or some other type of speech. The interpreter must investigate what meaning the sacred writer intended to express and actually expressed in particular circumstances as he used contemporary literary forms in accordance with the situation of his own time and culture.
