Syncretism in Christianity
Nascent Christianity appears to have incorporated many Jewish and pagan cultural elements, through a process of "Christianization" or "baptizing" them to conform with Christian belief and principles, at least partially, whilst discarding theologically or morally incompatible elements.
Note for example the strong connection between the thought of St. Augustine and Neoplatonic thought; and St. Thomas Aquinas' many citations of "The Philosopher" (Aristotle). Many scholars agree with this syncretism in principle, though they may tend to label any specific example as "controversial". Medieval scholasticism engaged in prolonged and bitter debate over the place of pre-Christian classicism within the official Church teachings.
Open Theists (a subset of Protestant Evangelicals) assert that Christianity by the 3rd and 4th centuries had incorporated Greek Philosophy into its understanding of God.
Syncretism did not play a role when Christianity split into eastern and western rites during the Great Schism. It became involved however with the rifts of the Protestant Reformation, with Desiderius Erasmus's readings of Plutarch.
In 1615 David Pareus of Heidelberg urged Christians to a "pious syncretism"[citation needed] in opposing the Antichrist, but few 17th-century Protestants discussed the compromises that might affect a reconciliation with the Catholic Church: Johann Hülsemann, Johann Georg Dorsche and Abraham Calovius (1612-1685) opposed the Lutheran Georg Calisen "Calixtus" (1586-1656) of the University of Helmstedt for his "syncretism".
(See: Syncretistic Strife.)
The modern celebrations of Christmas (as celebrated in the northern European tradition, originating from pagan Yule holidays), Easter (as celebrated in the eastern European tradition, with the incorporation of spring fertility rites) and Halloween exemplify details of Christian/pagan syncretism.
Earlier, the elevation of Christmas as an important holiday largely grew out of a need to replace the Saturnalia, a popular December festival of the Roman Empire.
Roman Catholicism in Central and South America has integrated a number of elements derived from indigenous and slave cultures in those areas (see the Caribbean and modern sections); while many African Initiated Churches demonstrate an integration of Christian and traditional African beliefs.
In Asia the revolutionary movements of Taiping (19th-century China) and God's Army (Karen in the 1990s) have blended Christianity and traditional beliefs.
Catholic apologists nonetheless often argue against "cafeteria Catholicism", or the act of "picking and choosing" what one wants to believe or practice.
One can contrast Christian syncretism with contextualization or inculturation, the practice of making Christianity relevant to a culture.
The Syncretistic Strife of the 17th century
The phrase "Syncretistic Strife" may refer to the theological quarrel provoked by the efforts of Georg Calixt and his supporters to secure a basis on which the Lutherans could make overtures to the Roman Catholic and the Reformed Churches. It lasted from 1640 to 1686.
Calixt, a professor at Helmstedt, had through his travels in England, the Netherlands, Italy, and France, through his acquaintance with the different Churches and their representatives, and through his extensive study, developed a more friendly attitude towards the different religious bodies than the majority of his contemporary Lutheran theologians.
While the latter firmly adhered to the "pure doctrine", Calixt tended not to regard doctrine as the one thing necessary for a Christian, while in doctrine itself he did not regard everything as equally certain and important. Consequently, he advocated unity between those who agreed on the fundamental minimum, with liberty as to all less fundamental points.
In regard to Catholicism, he would have (as Melanchthon once would have) conceded to the pope a primacy human in origin, and he also admitted that one might call the Mass a sacrifice.
On the side of Calixt stood the theological faculties of Helmstedt, Rinteln, and Königsberg; opposed to him stood those of Leipzig, Jena, Strasburg, Giessen, Marburg, and Greifswald.
Abraham Calov in especial opposed Calixt. The Elector of Saxony, for political reasons, opponsed the Reformed Church, because the other two secular electors (Palatine and Brandenburg) were "reformed", and were getting more and more the advantage of him. In 1649 he sent to the three dukes of Brunswick, who maintained Helmstedt as their common university, a communication in which he voiced all the objections of his Lutheran professors, and complained that Calixt wished to extract the elements of truth from all religions, fuse all into an entirely new religion, and so provoke a violent schism.
In 1650 Calov became a professor at Wittenberg, and he signalized his entrance into office with a vehement attack on the Syncretists in Helmstedt. An outburst of polemical writings followed. In 1650 the dukes of Brunswick answered the Elector of Saxony that the discord should not be allowed to increase, and proposed a meeting of the political councillors. Saxony, however, did not favour this suggestion.
An attempt to convene a meeting of theologians was not more successful. The theologians of Wittenberg and Leipzig now elaborated a new formula, condemning ninety-eight heresies of the Helmstedt theologians. This formula (consensus) was to be signed by everyone who wished to remain in the Lutheran Church. Outside Wittenberg and Leipzig, however, it was not accepted, and Calixt's death in 1656 ushered in five years of almost undisturbed peace.
The strife broke out afresh in Hesse-Cassel, where Landgrave William VI sought to effect a union between his Lutheran and Reformed subjects, or at least to lessen their mutual hatred. In 1661 he had a colloquy held in Cassel between the Lutheran theologians of the University of Rinteln and the Reformed theologians of the University of Marburg. Enraged at this revival of the syncretism of Calixt, the Wittenberg theologians in vehement terms called on the Rinteln professors to make their submission, whereupon the latter answered with a detailed defence. Another long series of polemical treatises followed. In Brandenburg-Prussia the Great Elector (Frederick William I) forbade (1663) preachers to speak of the disputes between the Evangelical bodies. A long colloquy in Berlin (September 1662 to May 1663) led only to fresh discord. In 1664 the elector repeated his command that preachers of both parties should abstain from mutual abuse, and should attribute to the other party no doctrine which was not actually held by such party. Whoever refused to sign the form declaring his intention to observe this regulation, was deprived of his position (e. g. Paul Gerhardt, writer of religious songs). This arrangement was later modified, in that the forms were withdrawn, and action took place only against those who disturbed the peace. The attempts of the Wittenberg theologians to declare Calixt and his school un-Lutheran and heretical were now met by Calixt's son, Friedrich Ulrich Calixt, The latter defended the theology of his father, but also tried to show that his doctrine did not so very much differ from that of his opponents. Wittenberg found its new champion in Ægidius Strauch, who attacked Calixt with all the resources of learning, polemics, sophistry, wit, cynicism, and abuse. The Helmstedt side was defended by the celebrated scholar and statesman, Hermann Conring. The Saxon princes now recognized the danger that the attempt to carry through the "Consensus" as a formula of belief might lead to a fresh schism in the Lutheran Church, and might thus render its position difficult in the face of the Catholics. The proposals of Calov and his party to continue the refutation and to compel the Brunswick theologians to bind themselves under obligation to the old Lutheran confession therefore remained unimplemented. On the contrary, the Saxon theologians were forbidden to continue the strife in writing. Negotiations for peace then resulted, with Duke Ernst the Pious of Saxe-Gotha especially active towards this end, and the project of establishing a permanent college of theologians to decide theological disputes was entertained. However, the negotiations with the courts of Brunswick, Mecklenburg, Denmark, and Sweden remained as fruitless as those with the theological faculties, except that peace was maintained until 1675. Calov then renewed hostilities. He now attacked not only Calixt, but also and particularly the moderate John Musæus of Jena. Calov succeeded in having the whole University of Jena (and after a long resistance Musæus himself) compelled to renounce syncretism. But this was his last victory. The elector renewed his prohibition against polemical writings. Calov seemed to give way, since in 1683 he asked whether, in the view of the danger which France then constituted for Germany, a Calixtinic Syncretism with "Papists" and the Reformed were still condemnable, and whether in deference to the Elector of Brandenburg and the dukes of Brunswick, the strife should not be buried by an amnesty, or whether, on the contrary, the war against syncretism should be continued. He later returned to his attack on the syncretists, but died in 1686, and with his death the strife ended.
The Syncretist Strife had the result of lessening religious hatred and of promoting mutual forbearance. Catholicism thus benefited, as Protestants came to better understand and appreciate it. In Protestant theology it prepared the way for the sentimental theology of Pietism as the successor of fossilized orthodoxy.
