How did theology evolve?
It has evolved significantly since ancient Greek philosophers, who laid the groundwork for modern theological inquiry. This article will explore the development of theology throughout history, its current state, and the various Christian theologies that exist.
Ancient Greece (500 BCE – 300 CE)
The earliest recorded philosophical discussions on theology date back to ancient Greece. Philosophers such as Thales of Miletus (c. 624 – c. 546 BCE), Anaximander (c. 610 – c. 546 BCE), and Xenophanes (c. 570 – c. 478 BCE) explored the concept of a single, all-powerful deity. These thinkers sought to understand the nature of the divine and its relationship with humanity. In particular, Xenophanes is notable for his critique of polytheism, arguing that multiple gods were unnecessary and that one supreme god was more plausible. His ideas had a lasting impact even on Western philosophy and theology today.
It is clear as we read the Bible that some of the first theologians we had, were Paul of Tarsus (5-65 CE), John the Evangelist, James, Simon Peter, Ignatius of Antioch (between 98 and 117) and Clement of Rome, Polycarp etc. Other early Christian apologists, like Justin Martyr (c. 100-165 CE) and Origen (c. 185-254 CE), developed the early Christian theology. Justin Martyr’s Apology provides an example of early Christian apologetics, where he argued that Christianity was a rational and moral faith. Irenaeus of Lyons (died c. 202), Irenaeus’ Against Heresies is another important work, which critiqued gnostic and other heretical movements within the early Church.
Even Melito of Sardis (180 CE), was a bishop in the city of Sardis (modern-day Sart in Turkey) who was regarded as one of the greatest Christian thinkers, writers, and apologists of his time, wrote to the stoic Roman emperor Marcus Aurelius Antoninus about the Christian faith. We also can name people like Clement of Alexandria and Tertullian (c. 160 – c. 220), these are just a few for this period, the list goes on.
Classical Period (300 BCE – 500 CE)
During the Hellenistic period, philosophers such as Plato (427 – 347 BCE) and Aristotle (384 – 322 BCE) continued to develop theological concepts. Plato’s theory of forms posited that abstract entities, such as justice and beauty, existed independently of the physical world and were accessible through reason.
Aristotle’s concept of the Unmoved Mover posited a prime mover or first cause that initiated the movement of the universe. This idea was later influential in Christian theology. Some Christians in this time were men like Ambrose (337– 397), Gregory of Nyssa (c. 330 – c. 395), Jerome (347–420) and Augustine (354–430). Clearly, the development of Christianity was shaped by the influence of Greek philosophy, particularly Aristotelianism. Much of the theological debates during this period centered on issues like the nature of God, the Trinity, and the relationship between faith and reason.
Early Christianity (500 CE – 1500 CE)
The rise of Christianity in the Roman Empire led to significant theological developments. Early Christian theologians, such as Justin Martyr (100 – 165 CE), Irenaeus of Lyons (130 – 202 CE), and Origen of Alexandria (185 – 254 CE), sought to establish a coherent understanding of God and humanity’s relationship with Him. Boethius (c. 477–525) and Gregory the Great (540–604), Peter Lombard (c. 1096–1159), Peter Waldo (c. 1140–1205), Francis of Assisi (c. 1181–1226) are just a few more we will mention here, however, there were more, and it stretches over a huge time period.
Medieval Period (500 CE – 1500 CE)
During the Middle Ages, theology became increasingly formalized through the development of scholasticism. Scholastics such as Thomas Aquinas (1225 – 1274 CE) synthesized Aristotelian philosophy with Christian doctrine, creating a comprehensive and systematic understanding of God. Aquinas’ Summa Theologica is a seminal work in this period, which addressed topics ranging from the nature of God to the sacraments. His synthesis of faith and reason remains influential in modern theology.
William of Ockham (1285-1347) was an English Franciscan friar, scholastic philosopher, apologist, and theologian, whose contributions to medieval thought were pivotal in shaping the intellectual landscape of 14th-century Europe. His significance extends beyond philosophy, as he is also widely recognized for his advocacy of Occam’s razor, a methodological principle that bears his name, which has become an enduring symbol of parsimony and simplicity in the search for truth.
John Wycliffe (c. 1323-1384), a notable English scholastic philosopher and Christian reformer, held a distinguished faculty position as a theology professor at the University of Oxford during his tenure. His theological propositions have been regarded as instrumental in laying the groundwork for Protestantism, predicated on his radical critique of clerical materialism. Furthermore, Wycliffe espoused a distinctive austere poverty for all clergy, which was met with significant controversy among orthodox contemporaries of his time. Many who followed him into later centuries adopted certain of his theological tenets, including the virtues of faith, predestination, and iconoclasm, as well as the notion of caesaropapism. Nonetheless, there were also those who challenged his views on the veneration of saints, the sacraments, requiem masses, transubstantiation, monasticism, and the legitimacy or role of the Papacy.
Jan Hus (c. 1369-1415) was a Czech theologian and philosopher who played a pivotal role in shaping the theological underpinnings of Hussitism, a key precursor to Protestantism, and the Bohemian Reformation. Serving as a master, dean, and rector at the Charles University in Prague between 1409 and 1410, Hus employed his academic credentials to challenge various aspects of Catholic ecclesiology, including simony, eucharistic doctrine, and other theological topics that had long been contested by Bohemian Catholics. As one of the earliest proponents of a Church reform movement, Hus is often regarded as the inaugural church reformer, despite some scholars attributing this distinction to John Wycliffe’s later efforts. The intellectual legacy of Hus had a profound impact on the development of Protestant theology, particularly in the person of Martin Luther, who was heavily influenced by Hus’s teachings. Ultimately, Hus’s conviction regarding ecclesiastical abuses led to his condemnation as a heretic and his tragic execution at the stake.
Reformation and Enlightenment (1500 CE – 1800 CE)
The Protestant Reformation (1517 CE) introduced significant changes to Christian theology, emphasizing individual interpretation of Scripture and the authority of the Bible. The Enlightenment emphasized reason, science, and individual experience, leading to a more liberal approach to theology.
The Protestant Reformation led by Martin Luther and John Calvin introduced significant theological changes. The Reformation emphasized the authority of Scripture, justification by faith alone, and the priesthood of all believers. Martin Luther (1483–1546) was the seminal figure of the Protestant Reformation, and his theological beliefs formed the basis of Lutheranism. Luther taught that salvation and, consequently, eternal life are not earned by good deeds; rather, they are received only as the free gift of God’s grace through the believer’s faith in Jesus Christ. Later works of Luther expressed anti-Judaistic views
Desiderius Erasmus (c. 1466 – 1536), commonly referred to as Erasmus was a Dutch Christian humanist theologian whose oeuvre encompasses a vast array of translations, literary works, essays, prayers, and letters. As a paradigmatic figure of the Northern Renaissance, his thought has had a profound impact on Western culture and Dutch identity, with his theological endeavours positing a synthesis of pacifism and pastoral tolerance as essential components of a nuanced understanding of religious and civic obligations.
Huldrych Zwingli (1484-1531), a prominent Swiss theologian, played a pivotal role in the Reformation movement in Switzerland, whose theological endeavours were significantly influenced by the works of Desiderius Erasmus. Notably, Zwingli’s ecclesiastical practice was characterized by his emphasis on expository preaching, which employed biblical exegesis as a methodological framework for articulating his interpretive approaches to the entire New Testament. Furthermore, his theological stance clashed with that of the Anabaptists, leading to a period of persecution that underscored the complexities and tensions within the Reformation.
Heinrich Bullinger (1504-1575) held a prominent position as a Swiss Reformer and theologian following Huldrych Zwingli’s leadership. His literary endeavours were marked by notable contributions to Reformed theology, including his co-authorship of the Helvetic Confessions with John Calvin. Furthermore, Bullinger engaged in ecumenical dialogue regarding the sacrament of the Lord’s Supper, collaborating with Calvin to develop a Reformed doctrine of this aspect of Christian worship. In addition, Bullinger demonstrated scholarly rigor by engaging with a range of theological texts, including Peter Lombard’s Sentences, Luther’s magisterial works such as The Babylonian Captivity of the Church and The Freedom of a Christian. Conversely, it was only upon recognizing that salvation is predicated on God’s grace rather than human merits that Bullinger underwent a transformative conversion to Protestantism.
John Calvin (1509-1564) was a French theologian, pastor, and reformer who played a pivotal role in shaping the Reformed tradition of Christian theology. His magisterial treatises on theology and church governance contributed significantly to the development of Calvinism, which systematically articulated its distinctive doctrines, including predestination and divine sovereignty. Notably, Calvin’s theological framework was deeply rooted in Augustine’s teachings and other Christian traditions, as he synthesized and elaborated upon existing ideas to form a comprehensive system of Christian theology.
The 17th-century intellectual landscape was shaped by several notable figures, including John Milton (1608-1674), who garnered significant recognition during his lifetime for his vocal defences of freedom of speech and freedom of the press. Milton’s impassioned arguments on these issues rendered him a target of suspicion among some quarters, with some viewing him as dangerously radical and heretical.
The prominent English Puritan theologian John Owen (1616-1683) occupied a distinguished position as church leader, holding office as senior pastor at Independent churches in England, and served as vice-chancellor of the University of Oxford, thereby solidifying his reputation as a leading figure in Reformed theology. Owen’s theological output, including his influential works on sin and human depravity, reflects his commitment to Calvinist interpretations of Scripture, which underscored the notion that humanity is radically fallen and incapable of saving itself through its own efforts.
John Gill (1697-1771) was a prominent English Baptist pastor, biblical scholar, and theologian who adhered to a robust Calvinistic soteriology. As a defender of Reformed theology, Gill provided extensive exegesis on the doctrine of salvation in his seminal work, “The Cause of God and Truth”, where he explicitly articulated the Five Points of Calvinism.
The Enlightenment, which followed, brought a renewed emphasis on reason and individualism. Thinkers such as Immanuel Kant (1724 – 1804 CE), now Kant is widely regarded as the “father of modern ethics” due to his seminal contributions, which integrated rationalism and empiricism to form a distinctive philosophical framework. In response to the intellectual challenge posed by scepticism, Kant produced the critically influential Critique of Pure Reason (1781), a work that not only established him as a major philosophical thinker but also laid the groundwork for subsequent philosophical debates in theology and beyond.
Kant’s moral philosophy posited that reason is the fundamental source of morality and that this understanding was grounded in his concept of the “categorical imperative,” which he believed to be an objective moral law. Furthermore, Kant’s aesthetic theory posited that beauty arises from a faculty of disinterested judgment, which he considered to be an essential aspect of human experience. Kant’s religious views were closely tied to his moral and epistemological theories, with his critique of metaphysics and the natural world serving as a foundation for his more general philosophical project. Throughout his work, Kant endeavoured to reconcile faith and reason, arguing that both were necessary components of a comprehensive understanding of human existence.
Friedrich Schleiermacher (1768-1834 CE) undertook a comprehensive examination of the nature of God through a nuanced fusion of philosophical and theological inquiry. As a pioneering figure in liberal Christianity, Schleiermacher is regarded as one of the most influential thinkers of his era, exerting a profound impact on Protestant theology. Schleiermacher’s seminal work, which sought to reconceptualize Christian theology within the context of modernity, earned him a reputation as one of the most important Protestant theologians in the period between John Calvin and Karl Barth. This distinction underscores Schleiermacher’s unique synthesis of traditional theological themes with liberal intellectual currents.
In contrast to Schleiermacher’s influential paradigm, which posited a pantheistic understanding of God that blurred the lines between divine and human existence, Karl Barth (1886-1968 CE) undertook a deliberate effort to challenge and subvert the intellectual trajectory inaugurated by Schleiermacher. Through his distinctive theology of the Word and the Decree of God, Barth sought to reclaim a more robust understanding of Christian doctrine, one that emphasised the transcendence and sovereignty of the divine.
Modern Period (1800 CE – present)
The modern period saw significant developments in theology, including liberal theology, existentialism and liberation theology. A new theological view of Dispensationalism was formed in the mid-1800s by John Darby (Plymouth Brethren) (1800-1882), D.L. Moody (1837–1899), Charles Ryrie (1925-2016) and Cyrus Scoffield (1843-1921) to name a few. This theological view interprets Scripture in a literalistic way and believes that God offers two salvation plans for humanity. Their theological framework is set up in such a way that they divide history into dispensations, in each age God interacts with people in a different way. The term “dispensationalism” was coined by Philip Mauro in his book The Gospel of Kingdom (1928). The Scofield Bible define a dispensation as “a period of time during which man is tested in respect of obedience to some specific revelation of the will of God”.
The Liberal movement emerged in the 19th century, exemplified by thinkers such as Rudolf Bultmann (1884 – 1976 CE), who sought to integrate faith with scientific and cultural advancements. With existentialism, theologians like Karl Barth (1886 – 1968 CE) and Reinhold Niebuhr (1892 – 1971 CE) emphasized the individual’s experience of God in an existential context. The movement of Liberation theology, exemplified by figures such as Gustavo Gutiérrez (1928 – 2019 CE), sought to address social justice issues and the poor from a theological perspective.
Contemporary Theology
Today, theology encompasses a broad range of perspectives and approaches. Some notable trends include:
- Postmodern Theology: This movement emphasizes the fragmented nature of modern experience and critiques traditional notions of God.
- Ecumenical Theology: Scholars like Thomas Merton (1915 – 1968 CE) have explored interfaith dialogue and cooperation between Christian denominations.
- Systematic Theology: Contemporary theologians such as N.T. Wright (1948 – present), John Polkinghorne (1937 – present), and Kathryn Tanner (1954 – present) continue to develop comprehensive systems of theology. It continues to develop comprehensive systems of theology, incorporating various philosophical and theological perspectives.
Different Christian Theologies
Within Christianity, various theologies have emerged over time. Some notable examples include:
Pentecostalism: Pentecostal theology focuses on the gifts of the Holy Spirit, such as speaking in tongues and healing. Notable figures include Charles Parham (1873 – 1929 CE), William Seymour (1870 – 1922 CE), and Oral Roberts (1918 – 2009 CE).
Catholicism: Catholic theology emphasizes the authority of Scripture, Tradition, and the Magisterium (the teaching authority of the Church). Key figures include Thomas Aquinas, John Paul II, and Benedict XVI.
Eastern Orthodoxy: Eastern Orthodox theology stresses the importance of sacraments, liturgy, and the role of tradition in understanding God’s nature. Notable figures include St. Augustine of Hippo, St. Gregory Palamas, and Patriarch Bartholomew I.
Protestantism: Protestant theology encompasses a wide range of perspectives, from Lutheran to Reformed, Baptist, and Pentecostal. Key figures include Martin Luther, John Calvin, John Wesley, and Charles Finney.
Evangelicalism: Evangelical theology emphasizes personal conversion, biblical authority, and evangelism. Notable figures include Billy Graham (1918 – 2018 CE), Francis Schaeffer (1939 – 1995 CE), and Timothy Keller (1950 – present).
Liberal Theology: Liberal theologians often emphasize the importance of reason, individual experience, and social justice. Key figures include Rudolf Bultmann, Reinhold Niebuhr, and Gustavo Gutiérrez.
