Perhaps you should say "one of the newest Bibles in Spanish." A Catholic version of the Bible in Spanish was produced in 1780. Later versions were produced in 1825, 1944, 1947, 1967, 1972, 1975, 1978, 1992, 1993, 1994 and 2006.
Fetus left out in this post but made clear in a later one was that the "bible" he brought to school was a KJV and that is why the good sister took it from him.
I got the 1967. Until then, if you wanted to buy one, all the Bibles were in Latin! What happened to the older translations? I don’t know, all I know is that, after Vatican II allowed for the Mass in vernacular, they made a great deal in Spain about translating the Bible into Spanish. Maybe I did not get the first Spanish Bible ever, but I did get the first available one!
