History of Dogma, Volume 2

A historical account written in the late 19th century. This work delves into the evolution of Christian doctrine from the early church to the formation of the Catholic Church, examining its interaction with Gnosticism and the philosophical ideas of the time. It aims to trace the development of core beliefs within Christianity, focusing on the establishment of what became recognized as orthodox Christian teachings. The opening of the book presents a historical overview, highlighting the conflict between the emerging structure of the Catholic Church and competing theological movements, particularly Gnosticism. Harnack discusses how the early Church faced challenges in defining its doctrinal standards and the authority of scriptural texts. He notes the significance of various church fathers, including Irenaeus and Tertullian, in articulating an apostolic tradition that would provide a foundation for Catholicism. Harnack emphasizes the goals of maintaining fidelity to early Christian roots while navigating the complexities introduced by differing interpretations of faith and authority within the diverse communities of early Christians.
