Scripture, Sacred Art and Catholic Symbolism
Revelation and Inspiration
Catholics believe God has communicated with humanity — this communication is called revelation. Revelation takes two main forms. Natural revelation is the knowledge of God that can be reached through reason and the observation of creation — the world itself points to its Creator. Special revelation is God’s direct communication through historical events, the prophets and supremely through Jesus Christ, the Word made flesh.
The Bible is the product of divine inspiration. Catholic teaching holds that God is the principal author of Scripture, working through human authors. This means the Bible is truly the Word of God, and yet also truly a human document — written in particular languages, by particular people, in particular historical and cultural contexts. The Second Vatican Council’s document Dei Verbum teaches that to understand what God intends to communicate, the reader must pay attention to what the human authors were actually saying and the literary forms they used.
Catholic teaching holds that Scripture is both fully divine (God is its ultimate author) and fully human (written by people in specific times and cultures). To interpret Scripture correctly, the reader must understand the literary form being used — whether the text is history, poetry, law, parable, prophecy or another genre.
Literary Forms in Genesis
The opening chapters of Genesis have been a source of rich debate. Catholics do not require a literal reading of Genesis 1–2 as a scientific account of origins. The Catechism of the Catholic Church and the teaching of Dei Verbum encourage attention to literary form. Genesis 1 has the structure of a liturgical poem — a rhythmic seven-day framework with refrains. Genesis 2 is a different account, more narrative in style, focusing on the garden and the human relationship with God.
Catholic scholars recognise that the Genesis creation accounts are primarily theological texts, not scientific reports. They communicate truths about who God is (Creator, good, personal), who humanity is (made in the image of God, called to relationship and responsibility), and what went wrong (the Fall, Original Sin). These truths remain authoritative for Catholics regardless of how the physical universe came into being.
Genesis 1:26–27 is the crucial text: “Let us make mankind in our image, in our likeness” — establishing the imago Dei (image of God). Catholic theology has reflected on this for centuries. St Augustine, St Thomas Aquinas and many others saw the imago Dei as humanity’s rational, moral and relational nature — the capacity to know God, to choose good and to love.
Not all Christians interpret Genesis the same way. Literalists (sometimes called young-earth creationists) hold that Genesis 1 is a straightforward historical account: the world was created in six twenty-four-hour days, a view sometimes associated with certain evangelical Protestant communities. They argue Scripture must be taken at face value on all matters, including the age and origins of the earth.
Day-age theorists propose that the six “days” of Genesis 1 correspond to long epochs of time. This allows a broad compatibility with the scientific account of deep time while retaining a sequential creation narrative. Other Christians, including many Catholics, embrace theistic evolution: God created the universe and set natural processes in motion through which all life, including humanity, developed. God’s special creative action is seen in the gift of a rational and moral soul, not in bypassing natural processes. Pope John Paul II in a 1996 address to the Pontifical Academy of Sciences affirmed that evolution is “more than a hypothesis” and is compatible with Catholic faith, provided that the spiritual soul is seen as directly created by God.
Sacred Art: Michelangelo’s Creation of Adam
One of the most famous images in the history of art, Michelangelo’s Creation of Adam (c.1508–1512) forms part of the ceiling of the Sistine Chapel in the Vatican. The fresco shows God giving life to the first human. It is usually read alongside two texts: Genesis 1:26–27, where humanity is made in God’s image, and Genesis 2:7, where God breathes life into Adam. God reaches across the void towards Adam, whose arm is extended in a mirror image — two hands almost touching. The gap between the fingertips has been interpreted as the space between the divine and the human, bridged by God’s initiative.
Theologically, the painting communicates core Catholic doctrines: God is personal (depicted in human-like form to make the divine act comprehensible), creation is an act of love and gift, and human beings are made in the imago Dei — called into relationship with their Creator. The work is not merely beautiful; it is catechetical — it teaches doctrine visually at a time when most worshippers could not read. The Sistine Chapel was built as the Pope’s own great chapel, and it is now where the conclave elects a new Pope: every surface reinforces Catholic faith in a visual theology.
Michelangelo’s Creation of Adam depicts Genesis 1:26–27 visually — God reaching across the void to give life to Adam. It communicates the imago Dei (humanity made in God’s image), the personal nature of God and the Catholic belief that human life is a divine gift. It is housed in the Sistine Chapel, Vatican City.
The Tree of Life Mosaic at San Clemente, Rome
The apse mosaic of the Basilica of San Clemente in Rome (twelfth century) presents a complex symbolic programme drawing together themes of creation, salvation and the Church. At the centre of the mosaic is the Cross of Christ, but the cross is also depicted as a Tree of Life — a reference that connects it to the tree in the Garden of Eden (Genesis 2–3) and to the tree of life described in the book of Revelation (22:2). This connection suggests that Christ’s Cross restores what was lost at the Fall: access to God and to eternal life.
From the cross-tree spread vines, tendrils and leaves, filling the apse with abundant imagery of growth and life. Within the imagery appear the symbols of the four Evangelists — the winged man (Matthew), the lion (Mark), the ox (Luke) and the eagle (John) — proclaiming that the Gospels carry the life of the Tree to the world. The dove — symbol of the Holy Spirit — appears above or near the cross. The mosaic thus presents a compressed vision of Catholic belief: the Trinity, the Incarnation, the Cross as salvation, the Scriptures and the Church all intertwined in one visual whole.
Catholic theology frequently describes Jesus as the New Adam. The idea comes from St Paul’s letter to the Romans (5:12–21) and 1 Corinthians (15:21–22): just as through one man (Adam) sin and death entered the world, so through one man (Christ) come grace and life. The San Clemente mosaic embodies this by placing the cross (the instrument of Christ’s death and resurrection) in the position of the Tree of Life — visually declaring that Christ as New Adam restores humanity’s access to God.
The Alpha and Omega symbols often appear near the cross in Byzantine and Romanesque art, reinforcing the theological claim that Christ is himself the beginning and end of all things — the one in whom creation finds its meaning and destiny. The Chi-Rho also frequently appears in early Christian art to identify the figure on the cross or in the apse as the Christ, Lord of all.
