For a treatment of what the framers of our confession meant, see http://www.theauthorizedversion.com/reformed-confessions-of-faith-and-the-traditional-text/From my viewpoint over the years, as an observer and not a participant, I have noticed that all three Reformed camps equivocate on the meaning of 'by His singular care and providence kept pure in all ages'.It's my hope that this will be of help for all sides of the textual debate to have more irenic future interaction on the subject.
KJO: The TR is 'pure'.
ET: The Greek Text 'stream' is pure.
CT: Anything we have or ever will have is pure because God 'preserved' it.
Is this a good thumbnail of the different positions?
