Arius taught that Christ was less than divine, that he was a creature made by God. Arius taught that only
God the Father was eternal and too pure and infinite to appear on the earth. Therefore, God produced
Christ the Son out of nothing as the first and greatest creation. The Son is then the one who created the
universe. Because the Son relationship of the Son to the Father is not one of nature, it is, therefore,
adoptive. God adopted Christ as the Son. Though Christ was a creation, because of his great position and
authority, he was to be worshipped and even looked upon as God. Some Arians even held that the Holy
Spirit was the first and greatest creation of the Son.
The First Council of Nicaea (A.D. 325)
This Council, the first Ecumenical Council of the Catholic
Church, was held in order to bring out the true teaching of the Church as opposed by the heresy of Arius.
It formally presented the teaching of the Church declaring the divinity of God the Son to be one substance
and one nature with that of God the Father.
“We believe in one Lord, Jesus Christ, the only Son of God, eternally begotten of the Father, God from
God, light from light, true God from true God, begotten, not made, of one Being with the Father
This heresy about the person of Christ was initiated by Nestorius, bishop of Constantinople, who denied
Mary the title of Theotokos (Greek: "God-bearer" or, less literally, "Mother of God"). Nestorius claimed
that she only bore Christ's human nature in her womb, and proposed the alternative title Christotokos
