The Council opened on October 11, 1962 and closed on December 8, 1965. This was the sixties, when our country and our culture were radically and drastically altered. Many who were involved in the translation of the Latin into English pushed for an interpretation of the liturgical language that would be relevant, familiar, and easily understood by everyone. In translating the Creed, the Latin word “consubstantialem” involved considerable debate. The direct translation “consubstantial” was unfamiliar; a word that few understood so the phrase “one in Being with the Father” was used instead. And for over 40 years we, as Catholics, have been repeating the phrase, generally without considering what it meant.Twenty-one Ecumenical Councils earlier, at the First Council of Nicaea (325 AD) the Bishops were in the midst of a debate concerning the very essence of Jesus, the Son of God. There were those who believed that Jesus was not divine, not God, but rather a very special creation of God, a super-human creature who resembled God but was not God. This view was promoted by a priest named Arius and is known as the Arian heresy. The Council of Nicaea was called to combat this heresy and the primary product of the Council was what we call today the Nicene Creed.
When we recite the Nicene Creed at Mass we say “begotten, not made” specifically because we believe that Jesus is not a creation of God but is “true God from true God.” The Bishops who debated and responded to the Arian heresy used the Greek word “homoousion” — which means of the same essence; in Latin the word was “consubstantialem” — to express the Divinity of Christ.
The council stated unequivocally that Jesus was neither like the Father nor nearly the same as the Father but was consubstantial (of the same substance) with the Father. The phrase “one in Being with the Father” fails to carry the same meaning as consubstantial. God is the creator of everything that was, that is, and that will ever be. Because of this we could say that all He has created is one in being with Him.
Clearly Jesus is not God’s creation so we must look at how to more fully express the relationship of the Father and the Son. The Council of Nicaea made this very clear, so we now say “…begotten, not made, consubstantial with the Father…”
