Did Isaiah really predict the Virgin birth?" looks at Isaiah 7:14 in relation to the NABRE translation.
Here is a little snippet from the conclusion:
Still, there was some “pastoral concern,” when the Catholic bishops authorized the New American Bible, Revised Edition, said retired Auxiliary Bishop Richard Sklba of Milwaukee, who was part of the review and editing team.
“There was discussion about keeping the traditional translation so that people have the benefit of continuity,” Sklba said. But in the big picture, changing Isaiah 7:14 doesn’t sever the connection between the prophecy and Matthew’s Gospel, he said. Isaiah stressed that Immanuel’s mother would be young, and Matthew emphasized her virginity. “The one does not deny the other,” Sklba said.
There are also some comments from our friend Mary Sperry. I wonder if Isaiah 7:14 will be changed back in the upcoming NAB revision?
