Heinrich Bullinger in the context of "Continental Reformed church"

Continental Reformed Christianity or Continental Reformed Protestantism is a part of Reformed Christianity within Protestantism that traces its origin to continental Europe. Prominent subgroups are the Dutch Reformed, Swiss Reformed, French Huguenot, Hungarian Reformed, and German Reformed Churches.

The term is used to distinguish these Churches from Presbyterian, Congregational, Reformed Anglican or other Calvinist Churches, which can trace their origin to the British Isles or elsewhere in the world. Notably, their theology is largely derived from the Swiss Reformation, as Switzerland (specifically Geneva and Zürich) was a base for the most influential Reformed theologians of the era. It was inaugurated by Huldrych Zwingli, who formulated the first expression of the Reformed faith. Swiss Reformation was more fully articulated by Martin Bucer, Heinrich Bullinger and especially John Calvin, who became recognized as the leading figure in the Reformed tradition. In the sixteenth century, the movement spread to most of continental Europe, sometimes with the protection of monarchs or members of the nobility, as in the Netherlands, Switzerland, Hungary, some German states, and France.

John Calvin (/ˈkælvɪn/; Middle French: Jehan Cauvin; French: Jean Calvin [ʒɑ̃ kalvɛ̃]; 10 July 1509 – 27 May 1564) was a French theologian, pastor and reformer in Geneva during the Protestant Reformation. He was a principal figure in the development of the system of Christian theology later called Calvinism, including its doctrines of predestination and of God's absolute sovereignty in the salvation of the human soul from death and eternal damnation. Calvinist doctrines were influenced by and elaborated upon Augustinian and other Christian traditions. Various Reformed Church movements, including Continental Reformed, Congregationalism, Presbyterianism, Waldensians, Baptist Reformed, Calvinist Methodism, and Reformed Anglican Churches, which look to Calvin as the chief expositor of their beliefs, have spread throughout the world.

Calvin was a tireless polemicist and apologetic writer who generated much controversy. He also exchanged cordial and supportive letters with many reformers, including Philipp Melanchthon and Heinrich Bullinger. In addition to his seminal Institutes of the Christian Religion, Calvin wrote commentaries on most books of the Bible, confessional documents, and various other theological treatises.

In Reformed theology, the Lord's Supper or Eucharist is a sacrament that spiritually nourishes Christians and strengthens their union with Christ. The outward or physical action of the sacrament is eating bread and drinking wine. Reformed confessions, which are official statements of the beliefs of Reformed churches, teach that Christ's body and blood are really present in the sacrament and that believers receive, in the words of the Belgic Confession, "the proper and natural body and the proper blood of Christ." The primary difference between the Reformed doctrine and that of Catholic and Lutheran Christians is that for the Reformed, this presence is believed to be communicated in a spiritual manner by faith rather than by oral consumption. The Reformed doctrine of real presence is called "pneumatic presence" (from pneuma, a Greek word for "spirit"; alternatively called "spiritual real presence" or "mystical real presence").

Early Reformed theologians such as John Calvin and Heinrich Bullinger taught that Christ's person, including his body and blood, are presented to Christians who partake of it in faith. This view of the real spiritual presence was formally formulated by both Calvin and Bullinger in the Consensus Tigurinus. The historic Reformed confessions of faith, including the Second Helvetic Confession (Continental Reformed), Westminster Confession (Presbyterian), Thirty-Nine Articles (Anglican), and Savoy Declaration (Congregationalist), hold to the doctrine of real spiritual presence.

The Helvetic Confessions are two documents expressing the common belief of Reformed churches, especially in Switzerland, whose primary author was the Swiss Reformed theologian Heinrich Bullinger. The First Helvetic Confession (1536) contributed to the confessional unity of the Protestant cantons of Switzerland against the Roman Catholic cantons, whereas the Second Helvetic Confession (1566) contributed to the confessional unity of Reformed churches across Europe, particularly due to the patronage it received from Frederick III, Elector Palatine, who had it translated into German.

The Consensus Tigurinus or Consensus of Zurich was a Protestant document written in 1549 by John Calvin and Heinrich Bullinger.

The document was intended to bring unity to the Protestant churches on their doctrines of the sacraments, particularly the Lord's Supper. Calvin’s views stood between the Lutheran view of Real Presence and the Zwinglian view of symbolism. He wrote the first draft of the document in November 1548, with notes by Bullinger.
