Theologian, b. at Wesel, 17 June, 1788; d. at Bonn, 11 May, 1877. He was appointed professor of theology at Bonn in 1826 and in 1832 he founded with his colleague, J.W.J. Braun (d. 1863), the "Zeitschrift für Philosophie und Katholische Theologie" (1832-52), the chief purpose of which was to defend the teachings of Hermes. He also published under the title "Christkatholische Dogmatik" (Münster, 1834-36) the theological writings which Hermes (d. 1831) had left in manuscripts. This publication was followed by sharp controversy, and eventually by the condemnation of the works of Hermes, which Pope Gregory XVI placed upon the Index, 26 September, 1835. In 1843, Achterfeldt incurred suspension from his professorial chair rather than sign the declaration of faith required by the Coadjutor Archbishop von Geissel of Cologne . Though Hermesianism lost ground and finally disappeared during the revolution of 1848, Achterfeldt clung to his views. In 1862, however, he was reinstated as professor, and in 1873, having made his submission to ecclesiastical authority, he was freed from suspension.

Catholic Encyclopedia

Designed to present its readers with the full body of Catholic teaching, the Encyclopedia contains not only precise statements of what the Church has defined, but also an impartial record of different views of acknowledged authority on all disputed questions, national, political or factional. In the determination of the truth the most recent and acknowledged scientific methods are employed, and the results of the latest research in theology, philosophy, history, apologetics, archaeology, and other sciences are given careful consideration.

No one who is interested in human history, past and present, can ignore the Catholic Church, either as an institution which has been the central figure in the civilized world for nearly two thousand years, decisively affecting its destinies, religious, literary, scientific, social and political, or as an existing power whose influence and activity extend to every part of the globe. In the past century the Church has grown both extensively and intensively among English-speaking peoples. Their living interests demand that they should have the means of informing themselves about this vast institution, which, whether they are Catholics or not, affects their fortunes and their destiny.
