In my opinion, the sources closest to best are books with
credible publisher.
Writers who are known for their orthodox doctrines and
presentation.
e.g Gordon Lindsay, James Dobson, John Calvin, C.S Lewis, Josh
MacDowell, Thomas A Kempis(One of the loved author), John MacArthur
and R.C Sproul
Usually most of the sources i've seen in internet, either have
various versions of a topic altogether, many assumptions and weak
conclusion, poor references of studies. Inconsistency.
Those which you've posted which were claimed to have been studied
by Christian scholars, i doubt their crediblity, maybe it's because
i've read different materials and it doesn't seem to telly at
all.
I tend to believe in the materials i read more than the internet
articles.
All in all, internet sources are subject to changes... 
Which means their stand and theories are still in studies.
I'm not sure how much you hold on to internet theories.
I for one is not a fan of it.
Reading is ok. But believing is another. Using it as to answer or
reference to question is no no for me. Unless it is absolutely
trustworthy.
