Even though the term "unitarian" did not first appear until the 17th century in reference to the Polish Brethren, the basic tenets of Unitarianism go back to the time of Arius in the 4th century, an Alexandrian priest that taught the doctrine that only the Father was God, and that the Son had been created by the Father. Arians rejected the term "homoousios""" (consubstantial) as a term describing the Father and Son, viewing such term as compromising the uniqueness and primacy of God, and accused it of dividing the indivisible unit of the divine essence. Unitarians trace their history back to the Apostolic Age, arguing, as do Trinitarians and Binitarians, that their Christology most closely reflects that of the early Christian community and Church Fathers.
