Arianism was a theological movement of the fourth century that sought to redefine the relationship between God and Jesus Christ. At the center of Arianism were two key beliefs: first, that Jesus was not equal to God (contra to Nicene orthodoxy), but rather created by God; and second, that he was “like” or “similar” to God in some way (Stark, 1989). This belief system had huge implications for Christian theology at the time, particularly with respect to church councils such as those held at Nicaea and Constantinople. As such, it is important to examine both its lasting impact on Christianity and its role in shaping fourth century theology more broadly.
Describe the importance of Arianism in the formation of fourth century theology
One of the most significant impacts of Arianism on fourth-century theology can be seen in the Councils of Nicaea and Constantinople. The First Council of Nicaea (325 CE) was convened specifically to address Arianism; indeed, it is often referred to as an “anti-Arian council” due largely to its affirmation of the doctrine known as homoousios—that is, that Jesus Christ is equally divine with his Father (Brighton et al., 2008). This creed formed a cornerstone of what would become orthodox Christian doctrine; without it, much of subsequent Christian theological discourse could not have taken place. Similarly, while less directly focused on refuting Arian teaching than Nicaea I had been over half a century earlier, The Second Ecumenical Council at Constantinople (381 CE) nonetheless produced several creeds which spoke out against various aspects of Arian thought (Heinlein & Schlosser 2018). Thus both councils served as crucial turning points for Catholic orthodoxy generally—and anti-Aryan sentiment specifically—making them instrumental in furthering fourth century Christian thought more broadly.
In addition to these two central councils however, there are other ways in which we can trace evidence for Arianism’s influence on fourth century Christianity. To begin with scholars have identified several letters written by prominent church fathers during this period which discuss issues related either directly or indirectly related aspectsof Arius’ teachings(Friesen 2010). In particular St Athanasius’s Defense Against Arians stands out as oneof most definitive treatises from this era – having shaped countless generations of Christian theologians thereafter (Moule 1999). It should also be noted that although some aspects of Arius’s original ideologies have been rejected within most denominations today many churches still incorporate certain elements into their liturgies& worship practices–a testament to its continuing presence within Christianity even today .
