What was arainism?

Answer 1

Arianism was a Christian theological doctrine that emerged in the early centuries of Christianity, primarily associated with the teachings of Arius, a priest from Alexandria. It emphasized that Jesus Christ, while divine, was created by God the Father and thus distinct from Him, challenging the traditional view of the Trinity. This belief led to significant controversy and was ultimately deemed heretical by the Council of Nicaea in 325 AD, which affirmed the co-equal and co-eternal nature of the Son with the Father. Arianism significantly influenced early Christian debates about Christ's nature and the formulation of orthodox Christian doctrine.
