absolute truth. The original intention to pacify conflicts between the denominations in the 19th century turned into its opposite: Confession bore the ground for new conflicts, as for example in the Cologne conflict about mixed marriages in 1837 (article in German). The Roman Catholic Church refused to consider itself as merely a confession. However ahistorical the terminology (cf. the latest semantical research of L. Hölscher), historians talk about the Early Modern period as a “confessional age” (first evidence: Ernst Troeltsch, 1906) and with good reasons use the terms of confessionalization and confessionalism. In the second half of the 19th century the term confessionalism occurred in dictionaries. It referred to internal Protestant conflicts (orthodoxy v. “living” Protestantism), to conflicts between different confessional groups, to everyday resentments and to any exaggerated emphasis of religious identity against competing identities. The Catholic Staatslexikon in 1959 defines Confessionalism as the “endeavour of the confessions to defend their religious doctrine” and their identity, in opposition to indifferentism, but it also meant the “overemphasis of confessional differences, esp. transferring them into the realm of state and society”. In later editions of dictionaries there is no lemma any more since the phenomenon lost its wider impact. Confessionalism exerted a severe impact on European social and political history between 1530 and 1648 and again between 1830 and the 1960s. Nowadays confessionalism is of minor relevance in European state churches. It rose to importance in the early 19th century and vanished in the 1960s. This is why some scholars talk about this time-period as a "second confessional age", comparing the dimensions of confessionalism with the "first confessional age" (16th to 17th centuries, for example Lutheran orthodoxy, Reformed scholasticism, Tridentine-era Catholicism, and the Thirty-nine Articles in Anglicanism). In intra-Christian dialogue, confessionalism was a significant consideration during the colloquies of Regensburg, Marburg, Montbéliard, and Kassel. However, various European free churches today consider their confessions to be important, for example, the Evangelical Lutheran Free Church and the Independent Evangelical-Lutheran Church both require clergy and congregations to declare a quia subscription to the Book of Concord, as such the denominations are classified as being Confessional Lutheran. Those that are or were part of the Confessing Movement who eventually deemed dealing with theological liberalism and theological progressivism within Mainline Protestant denominations as not being tenable anymore would later join or start Confessional Churches and Denominations that continue with the traditions of their respective denominations and
