The goal is to arrive at meaning, not to be sure that the translation reflects the grammar and usage of the original.
“The goal is to arrive at meaning” sounds more like interpretation than translation to me. That’s what got us “I am not worthy to receive you” instead of the words of the centurion. While the meaning is important, there is meaning
even in a very direct translation, and sometimes catechesis is the proper avenue for providing meaning. A translation that interprets too much (to provide meaning) can sometimes restrict the meaning too much and omit the possibility of other meanings to be derived from the text.
“Credo” means “I believe,” but in the context of the Nicene Creed perhaps the true meaning expressed in English is “we believe.”
Well,
perhaps. But according to the Catechism, “I believe” is “the Church, our mother, responding to God by faith.” (CCC 167) And the magisterial document governing the new translation,
Liturgiam Authenticam, addresses this change specifically:
65. … The Creed is to be translated according to the precise wording that the tradition of the Latin Church has bestowed upon it,
including the use of the first person singular, by which is clearly made manifest that “the confession of faith is handed down in the Creed, as it were, as
coming from the person of the whole Church, united by means of the Faith.” (Aquinas, Summa Theologiae, IIaIIae, I, 9)
The statement “I am not worthy to receive you” may convey more meaning than “I am not worthy that you should come under my roof.”
Perhaps you’d like to read
my explanation of these words?
“Consubstantial” seems like an anglicized Latin adjective, whereas “one in being with” is straightforward, plain English, but if the translators see the need, then so be it.
Should we also omit words like “pastor” from our English liturgy, since those are
straight out of the Latin? The word consubstantial is essentially an anglicized Latin word, but that’s not in itself a reason to disqualify it. Some dictionaries
do have that word in them, by the way.
