The Synod of Dort (Dutch: Synode van Dordrecht) was an international Reformed church council convened in Dordrecht, the Dutch Republic, from 23 November 1618 to 19 May 1619 (NS). Called primarily to resolve a doctrinal dispute within the Dutch Reformed Church over the teachings of Jacobus Arminius and his followers (the Remonstrants), the Synod produced the Canons of Dort, a confessional statement articulating five points of Calvinist soteriology that became foundational to Reformed orthodoxy. The Synod's rulings, their ecclesiastical authority, and their theological adequacy remain subjects of ongoing debate among Protestant theologians and historians.

The Synod arose from controversy within the Dutch Reformed Church following the death of Arminius in 1609. His followers issued the Remonstrance of 1610, a five-article document challenging Calvinist doctrines of unconditional election, limited atonement, and irresistible grace. The Counter-Remonstrants, who held to stricter Calvinist formulations, appealed to civil and ecclesiastical authorities for a national synod to adjudicate the dispute. Political dimensions were substantial: the conflict aligned with factional struggles between the Arminian-sympathizing Advocate of Holland, Johan van Oldenbarnevelt, and the Stadtholder Maurice of Nassau, who supported the Counter-Remonstrants. For fuller treatment of the events leading to and following the Synod, see synod-of-dort-history.

The Synod's primary doctrinal output, the Canons of Dort, addressed each of the five Remonstrant articles in turn. The resulting positions are frequently summarized by the acronym TULIP, though that formulation is a later, English-language construct not used by the Synod itself:

• Total depravity - human nature is wholly corrupted by original sin, leaving no capacity to seek God apart from divine grace.
• Unconditional election - God's election of individuals to salvation is not conditioned on foreseen faith or merit.
• Limited (or definite) atonement - Christ's atoning work was intended specifically for the elect.
• Irresistible (or efficacious) grace - the Holy Spirit's regenerating work cannot ultimately be resisted by those whom God elects.
• Perseverance of the saints - those truly elected will persevere in faith to the end.

The Synod included delegates not only from the Dutch provinces but also from England, Scotland, the Palatinate, Hesse, Switzerland, Nassau, East Frisia, and Bremen, lending its decisions an international Reformed character. The Remonstrants were summoned as defendants rather than participants and were ultimately condemned and removed from their offices.

The Synod of Dort remains a living reference point in Reformed, Arminian, and broader Protestant theological discussion. Key areas of ongoing debate include the precise scope of “limited atonement” and whether the Canons require the narrowest reading of that doctrine; the relationship between the Canons and earlier Reformed confessions such as the Belgic Confession and the Heidelberg Catechism; and the degree to which political circumstances shaped what were presented as purely doctrinal conclusions. Historians also continue to examine the Synod's role in the execution of Oldenbarnevelt and the broader suppression of Arminianism in the Dutch Republic as intertwined with confessional questions.

• Classical Calvinist / Dortian Orthodox - The Canons of Dort faithfully articulate the soteriological teaching of Scripture and the Reformation heritage. The Synod's decisions are binding confessional standards for Reformed churches. See synod-of-dort-dortian-orthodox-viewpoint.

• Arminian / Remonstrant - The Synod was a politically compromised proceeding that condemned a legitimate evangelical position without fair hearing. The five Dortian points misrepresent or contradict Scripture's teaching on human freedom and divine love. See synod-of-dort-arminian-viewpoint.

• Amyraldian / Four-Point Calvinist - The Synod's treatment of the atonement's extent does not require the strict particularist reading later imposed on it; a hypothetical universal atonement can be reconciled with Dortian election. See synod-of-dort-amyraldian-viewpoint.

• Revisionist Historical - The Synod's theological conclusions cannot be properly assessed apart from the political and factional context of the Dutch Republic; the two dimensions are inseparable in explaining both the outcome and its aftermath. See synod-of-dort-revisionist-historical-viewpoint.

• Ecumenical / Post-Confessional Protestant - The Dort-Arminianism divide, while historically significant, need not be treated as definitively church-dividing; both traditions share enough soteriological common ground that confessional boundaries drawn at Dort are overstated. See synod-of-dort-ecumenical-viewpoint.

• Political manipulation of the Synod - Critics have argued that Maurice of Nassau engineered the Synod's composition and outcome to destroy his political rivals, and that the subsequent execution of Oldenbarnevelt was inseparable from the doctrinal condemnations. See synod-of-dort-political-manipulation-controversy.

• Treatment of the Remonstrants - The Synod's refusal to seat the Remonstrants as participants rather than defendants, and the mass ejection of Arminian ministers from their pulpits following the Synod's close, generated lasting controversy about procedural fairness.
