Not one time does the author use the correct Greek word that is used in all the resurrection texts. I'll list them for you;
[Matthew 28:1] oye de sabbatwn th epifwskoush eiV mian sabbatwn hlqen maria h magdalhnh kai h allh maria qewrhsai ton tafon
[Mark 16:2] kai lian prwi ths mias sabbatwn ercontai epi to mnhmeion anateilantoV tou hliou
[Luke 24:1] th de mia twn sabbatwn orqrou baqeos hlqon epi to mnhma ferousai a htoimasan arwmata kai tines sun autais
[John 20:1] th de mia twn sabbatwn maria h magdalhnh ercetai prwi skotiaV eti oushV eiV to mnhmeion kai blepei ton liqon hrmenon ek tou mnhmeiou
The word the author of your article uses is SABBATON. It doesn't mean the same thing. Here is an example of the correct usage of SABBATON: [Mark 2:27] kai elegen autoiV to sabbaton dia ton anqrwpon egeneto ouc o anqrwpoV dia to sabbaton i.e. "And he said unto them, The sabbath was made for man, and not man for the sabbath."
MIA TWN SABBATWN does not mean "First Day of the Week". SABBATWN means Sabbaths (plural) and your article does not say "First day of the weeks".
You might write and ask Mr. Lyons why he doesn't use the correct word. I realize people fight tooth and nail to preserve their Sunday heritage.....but to purposely use a word in their article that doesn't even appear in any of the Greek passages......is disingenuous.
A very interesting article.
Not sure if I buy it, mind you, but interesting.
I have increasingly noticed how badly we have strayed from original Christian beliefs, so I see this as very plausible.
