I am dusting off this thread to thank inthecloud for pointing out recently that
Biblia Clerus apparently uses the RSV-CE for its presentation of Scripture in English. I have looked at Luke 1:28, 34, Romans 5:5, 8:11, 9:5 and John 19:5 among others. Based on mmortal’s handy verse comparison
reference, it looks to me to be consistent with an Oxford RSV-CE (which has a 1971 New Testament base), but it is unfortunately labeled 1966 which would imply (wrongly in this case) an Ignatius RSV-CE. Nevertheless, I think it possible that this is the first online RSV-CE that might actually fully match a printed version.
