Arianism was the fourth century evolution of adoptionism, in which Arius made a concession to the mainstream by accepting a quasi-divinity in Jesus Christ. But this was an acquired divinity, an earned divinity, and a divinity that was less than that of the Father. The controversy led to the first worldwide (ecumenical) council of bishops, the Council of Nicaea, in the year 325 AD, and it ultimately led to the crafting of the Nicene Creed, as the Church’s definitive statement of orthodox faith.
