The Synod of Dordt 1618/1619 was one of the most important church councils in the history of the Reformed tradition. International delegates from all over Europe served as important participants and played a significant role in the evaluation of Remonstrant doctrine and in the formation of the Canons of Dordt. The Synod made important pronouncements on other issues such as Sunday observance, catechism instruction and theological education. Given the continuing worldwide historical significance of the Synod’s Canons and church order, the absence of a critical scholarly edition of the majority of documents of the Synod is remarkable. The Johannes a Lasco Bibliothek in Emden, a leading research center for the history and theology of Reformed Protestantism, has taken the initiative to edit the Acts and documents of the Synod of Dordt. The edition is organized as a RefoRC project, with the participation of other institutions and scholars in Europe and North-America. Vol. II/1 edits the Convening of the Synod.
