For them, early Christianity eventually changed after the edicts of Emperor Constantine I and his sentence pronounced on Arius, which was later followed by the declaration by Emperor Theodosius I in the Edict of Thessalonica, cunctos populos of February 380 that Christianity as defined in the Nicene Creed was the official religion of the Roman Empire. A year later, the Second Ecumenical Council confirmed this in a revised Creed. Nontrinitarians dispute the veracity of the Nicene Creed based on its adoption nearly 300 years after the life of Jesus as a result of conflict within pre-Nicene early Christianity during a dramatic shift in Christianity's status.
