Arianism

n. Christian heresy taught by Arius denying the divinity of Christ and declaring that Christ was a created being

This article is about theological views similar to those of Arius. Aryan is an unrelated linguistic and ethnic concept. The term Arians may also refer to Polish brethren. Arianism is most commonly used to refer to the theological positions made famous by the theologian Arius (c. AD 250-336), who lived and taught in Alexandria, Egypt, in the early 4th century. The most controversial of the teachings of Arius dealt with the relationship between God the Father and the person of Jesus and conflicted with trinitarian christological positions which came to dominate the Roman Church (and hence the modern Roman Catholic and Eastern Orthodox Churches and most other denominations).

Arianism was the focus of the first Church council, the Council of Nicea . Its founder was Arius, who had developed an explanation for the Christian godhead. He did not believe in the Trinity , but instead held that God the Father was the only god and that Jesus and the Holy Spirit were created. Jesus was seen as the Prince of Angels who had come to earth and made himself into a human. (For the purposes of this course, we will ignore the issue of the Holy Spirit.) This explanation allowed Arius to maintain two important Christian ideas, namely, the oneness of God (monotheism) and the idea that Jesus was a historical figure who actually did the things he appeared to do--such as die (how can a god die?). The problem with it was that Arius' explanation also made Jesus into a created being, a "creature," rather than part of God.
