Arian (adj.)
1530s, pertaining to the doctrines of Arius, priest in Alexandria early 4c., who posed the question of Christ's nature in terms which appeared to debase the Savior's relation to God (denial of consubstantiation). Besides taking an abstract view of Christ's nature, he reaffirmed man's capacity for perfection. The dissention was widespread and split the Church for about a century during a crucial time.
