Jacobus Arminius (; 10 October 1560 – 19 October 1609), the Latinized name of Jakob Hermanszoon, was a Dutch Reformed minister and theologian during the Protestant Reformation period whose views became the basis of Arminianism and the Dutch Remonstrant movement. He served from 1603 as professor in theology at the University of Leiden and wrote many books and treatises on theology.

Following his death, his challenge to the Reformed standard, the Belgic Confession, provoked ample discussion at the Synod of Dort, which crafted the five points of Calvinism in response to Arminius's teaching.

Early life

Arminius, was born in 1559 or 1560 in Oudewater, Utrecht. He became an orphan while still young. His father Herman, a manufacturer of weapons, died, leaving his wife a widow with small children. He never knew his father, and his mother was killed during the Spanish massacre at Oudewater in 1575.

The child was adopted by Theodorus Aemilius, a priest inclined towards Protestantism. Around 1572 (the year Oudewater was conquered by the rebels), Arminius and Aemilius settled in Utrecht. The young Jacobus studied there, probably at the Hieronymusschool. After the death of Aemilius (1574 or 1575), Arminius became acquainted with the mathematician Rudolph Snellius, also from Oudewater. The latter brought Arminius to Marburg and enabled him to study at the Leiden University, where he taught. In 1576, Arminius was registered as a liberal arts student at the newly opened Leiden University.

Theological studies and ministry

Arminius remained a student at Leiden from 1576 to 1582. Although he enrolled as a student in Liberal Arts, this allowed him to pursue an education in theology, as well. His teachers in theology included Calvinist Lambertus Danaeus, Hebrew scholar Johannes Drusius, Guillaume Feuguereius (or Feugueires, d. 1613), and Johann Kolmann. Kolmann is now known for teaching that the overemphasis of God's sovereignty in high Calvinism made God "a tyrant and an executioner". Although the university in Leiden was solidly Reformed, it had influences from Lutheran, Zwinglian, and Anabaptist views in addition to Calvinism. One Leiden pastor (Caspar Coolhaes) held, contra Calvin, that civil authorities did have jurisdiction in some church affairs, that it was wrong to punish and execute heretics, and that Lutherans, Calvinists, and Anabaptists could unite around core tenets. The astronomer and mathematician Willebrord Snellius used Ramist philosophy in an effort to encourage his students to pursue truth without over reliance on Aristotle. Under the influence of these men, Arminius studied with success and may have had seeds planted that would begin to develop into a theology that would later question the dominant Reformed theology of John Calvin. The success he showed in his studies motivated the merchants guild of Amsterdam to fund the next three years of his studies.

In 1582, Arminius began studying under Theodore Beza at Geneva. He found himself under pressure for using Ramist philosophical methods, familiar to him from his time at Leiden. Arminius was publicly forbidden to teach Ramean philosophy. After this difficult state of affairs, he moved to Basel to continue his studies.

He continued to distinguish himself there as an excellent student. In 1583 Arminius was contemplating a return to Geneva when the theological faculty at Basel spontaneously offered him a doctorate. He declined the honor on account of his youth (he was about 24) and returned to the school in Geneva to finish his schooling in Geneva under Beza.

Commendations from Beza and Grynaeus

Upon the conclusion of Arminius' studies and a request for him to pastor in Amsterdam, Beza replied to leaders in Amsterdam with this letter:

"...Let it be known to you that from the time Arminius returned to us from Basel, his life and learning both have so approved themselves to us, that we hope for the best from him in every respect, if he steadily persists in the same course, which, by the blessing of God, we doubt not he will; for, among other endowments, God has given him an intellect well-suited both to the apprehension and to the discrimination of things. If this henceforward be regulated by piety, which he appears assiduously to cultivate, it cannot but happen that this power of intellect, when consolidated by mature age and experience, will be productive of the richest fruits. Such is our opinion of Arminius — a young man, unquestionably, so far as we are able to judge, most worthy of your kindness and liberality" (Letter of 3 June 1585 from Beza to Amsterdam).
