Paul wrote two letters to the Corinthinians:
In my experience, people use all kinds of colloquial language to refer to Chapters and verses inside these. For example:
"Two Corinthians Three Seventeen"
has the same semantic meaning as
"The Second Epistle to the Corinthians Chapter three verse seventeen."
It seems to me that the cultural style of reference has no correlation to knowledge of the Bible.
My question is: Is there any substantive difference between the verbal reference "second Corinthians" and "two Corinthians"?
