Top Ten Most Influential Christian Theologians

Christian theologians are scholars that have studied the area of Christianity in depth. They are often the academics who defend the faith and explain the most difficult aspects of the faith. They are, arguably, some of the smartest people to have ever lived. Some have had an incredible influence in the Faith and theories have gained considerable amount of traction. Today we'll be looking at the ten most influential theologians. Note this list is not about the best, but instead who made the most significant changes to the thinking of the time and whose theories are still held as a staple in the Faith. For the purposes of this list, I will not be listing figures from the Bible such as Paul the Apostle, Simon Peter, or even Jesus himself. Hope you enjoy and feel free to comment or remix.
The Top Ten
1 Martin Luther Martin Luther was a German professor of theology, composer, priest, monk and a seminal figure in the Protestant Reformation.

Martin Luther (1483-1546) was by far the most influential theologian. Luther was the leader of the Reformation and spoke heavily against the Catholic Church. His arguments against the Papacy, transubstantiation, and indulgences in the form of the "95 Theses" were a watershed moment in the religious world.

Luther also had very influential views regarding atonement and Sola Scriptura. He was one of the first theologians to openly develop Substitutionary Atonement (scholars disagree on whether Luther supported Penal Substitutionary Atonement). He was also one of the first theologians to endorse the Justification theory, a middle ground between Calvinism and Catholicism.

Martin Luther's influence in the Faith cannot be understated.

2 Thomas Aquinas

Thomas Aquinas (1225-1274) is immensely important in the Faith. He wrote the "Summa Theologica," which remains to this day one of the best books explaining theology. He touches on almost everything in the book.

Aquinas was also one of the first Christian apologists. Aquinas's Five Ways is taught in almost every denomination. He was a proponent of the satisfaction view of atonement. Despite being Catholic, Aquinas is one of the most highly respected and influential theologians in most churches.

3 Augustine of Hippo

Augustine (354-430) was one of the very first theologians. He wrote a lot on the soul-body union and more philosophical ideas. He was the first theologian to develop a systematic view of amillennialism.

Augustine also developed the City of God theory, which is a beautiful piece of writing to comfort Christians. He is most popular for his theories on original sin. This theory would be one of the staples of Catholicism and lead the way to infant baptism.

4 John Calvin

John Calvin (1509-1564) is obviously the key advocate of Calvinism. Calvinism has entrenched itself in many Church doctrines and is staunchly held to. Calvin takes a very radical view of predestination and even believes in double predestination, which is the foundation of Calvinism.

Calvin is also a Papal denier and transubstantiation denier like Luther, but splits with Luther on Sacraments, believing only Baptism and Communion are God-ordained. Calvin was also an advocate of Substitutionary Atonement, limited atonement, and was an early supporter of Penal Substitutionary Atonement.

5 Athanasius of Alexandria

Athanasius (296/298-373) was a very influential Church Father and theologian. He is most known for his passionate stand against Arianism and as a key promoter of Trinitarianism. He was one of the biggest proponents of the homoousios and the Logos.

Athanasius was also the first person to list all 27 books of the New Testament we see today as Biblical canon.

6 Origen

Origen (185-253) was one of the earliest theologians. He was the very first person to propose the Ransom Theory of Atonement in its full form. One of his biggest teachings was the preexistence of souls.

Origen was also an early Christological scholar. He significantly developed the ideas of the Trinity and the Logos. However, for some reason, he believed that the Son was less than the Father and the Spirit was less than the Son.

7 Jonathan Edwards

Jonathan Edwards (1703-1758) was definitely more well known as a fiery preacher from the Revivalist era. He was one of the first "Fire and Brimstone" preachers. He is most known for his sermon "Sinners in the Hands of an Angry God."

He was an ardent supporter of Penal Substitutionary Atonement. He was much more influential in the world of preaching, but he did have great theological influence.

Hugely influential, particularly in the First Great Awakening. Sinners in the Hands of an Angry God remains one of the greatest sermons of all time.

8 Ignatius of Antioch

Not much is known about Ignatius, but it has been said that he was a follower of John the Apostle. He was one of the first people to promote the change from Sabbath to the Lord's Day.

He was also an early advocate of the Deity of Christ. He was the first person to endorse a single bishop at the head of the Church, and he used the word Catholic when describing the Church (though all Catholic means is universal and was used way before this time).

9 C.S. Lewis Clive Staples Lewis (29 November 1898 – 22 November 1963) was a British novelist, poet, academic, medievalist, literary critic, essayist, lay theologian, broadcaster, lecturer, and Christian apologist... read more

C.S. Lewis (1898-1963) is definitely more well known as an author and Christian apologist. His theology slips into his writing, though. He is an advocate for Ransom Theory Atonement and Christus Victor.

He is also famous for Lewis's Trilemma, which is used in apologetics but is also very theological in essence. Thank you for reading this list!

10 John Wesley

John Wesley (1703-1791) was another revival preacher and was one of the biggest advocates of Arminianism, which set him at odds with Calvinists. He and his brother, Charles, were advocates of Penal Substitutionary Atonement.

John Wesley was also one of the first people to invite women to preach.

The Contenders
11 Soren Kierkegaard
12 Reinhold Niebuhr
13 Desmond Tutu
14 Charles Spurgeon

Spurgeon deserves a higher ranking. He was a great Biblical teacher and will always inspire me with his simple yet beautiful messages. He also led the largest Protestant church of his time.

Spurgeon was one of the best preachers ever, but theology wasn't his biggest priority.

15 Dietrich Bonhoeffer
16 Pope John Paul II Pope John Paul II served as Pope and sovereign of the Vatican City State from 1978 to 2005. He is called Saint John Paul the Great by some Catholics.
17 Billy Graham William Franklin Graham Jr. was an American evangelist, a prominent evangelical Christian figure, and an ordained Southern Baptist minister who became well-known internationally in the late 1940s.
18 Teresa of Ávila
19 Huldrych Zwingli
20 Albert Schweitzer
21 Pope Pius IX
22 Pope Francis Pope Francis is the 266th and current Pope of the Roman Catholic Church, a title he holds ex officio as Bishop of Rome, and Sovereign of the Vatican City.
23 Hildegard of Bingen
24 Philipp Melanchthon
25 Friedrich Spee
