A censor librorum is a Roman Catholic ecclesiastical authority charged with the task
of reviewing texts and granting to them a decree of nihil obstat, or their church’s authoritative approval. Nihil obstat is Latin for “nothing
stands in the way”. If your commentary or explanation of church doctrine has
that declaration on it, you are good to go in the Catholic world.
Not being Roman Catholic, and because my comprehension
of Latin is pretty much limited to Veni,
vidi, vici, I had to look that up.
All to say that back in 2004, a censor librorum declared the following
explanation of Genesis 38:8-10 to be “free of doctrinal or moral errors”. Take
that for what it’s worth.
