Yeah I find a lot of the changes to be arbritrary and an unneccessary complication. They have also changed “one in being with the Father” to “consubstantial with the Father” which means one in being with the Father.
I had another thought on the word “consubstantial”.
It’s true that no one is likely to know the meaning of the word the first time they hear it. One needs to be educated in orthodox Christology to understand the word. The words “one in being” on the other hand are understood by anyone who knows English.
The thing is, “one in being” could be interpreted in any number of ways, orthodox or heretical. In order for the Catholic to know what the phrase means, he or she needs to be similarly educated in orthodox Christology, probably including an introduction to the word “consubstantial”.
The thing is, when someone hears the word “consubstantial” and doesn’t understand it, they know they don’t understand it and, if they care, they can go and find out what it means, which is a very definite Christian doctrine since the word itself was coined to describe the relationship between the Father and the Son.
If, on the other hand, they hear “one in being” and don’t understand it, they may be more prone to subject the words to their own private interpretation, which may be lead to error. Thus there is a equal need for education with both phrases, but greater danger of error with “one in being.”
