Arianism was against:
Arianism opposes the concept of the equality of Persons within the Trinity, asserting that Jesus Christ is not of the same essence as God the Father. This belief was formally challenged and deemed heretical during the Council of Nicaea. As a result, Arianism contrasts sharply with traditional Christian views on the unity and equality of God within the Holy Trinity.
Arianism is a significant theological belief that arose in the early Christian church, primarily attributed to Arius, a Christian priest of Alexandria in the third and fourth centuries. The main tenet of Arianism is the belief that Jesus Christ, while divine, is not co-eternal or of the same essence as God the Father. This belief directly contradicts traditional Christian views regarding the equality of Persons within the Holy Trinity, specifically in regards to God the Father, God the Son (Jesus Christ), and the Holy Spirit.
Therefore, Arianism was particularly against the concept of the equality of Persons in the Trinity, which asserts that all three persons are fully and equally God. This belief led to significant theological battles in early Christianity, resulting in the Council of Nicaea in 325 AD, where Arianism was deemed heretical and the Nicene Creed was established to reaffirm the belief in the unity of God and the co-equal nature of the Father and the Son.
