The question as to whether the lectionary is likely to be based on another translation the the NAB is negative. I, however, happen to like the NABRE (maybe I’m dumb for that). I’ve read about about some of the “theological issues.” in regards to this translation, but I like it nonetheless. I mean, aren’t we, as Catholics, to be tempering our interpretations of scripture with what Holy Mother Church teaches us anyway? So if we, in the course of reading our terrible NABRE translation, have a doctrinal question that comes up, we can check a number of sources to find out what the church teaches on the matter.
