I hope you do not mind if I borrow your explanation of the new sabbath…
I like your insight here…which is what i am trying to get across Remnant1:
God, in these early Jewish-Christian’s minds, was creating new life now. (Matthew 28:1) God in a sense was working again, making us into new creations, and with sin defeated we humans could rest.–2 Corinthians 5:17, Hebrews 4:9.
This new day of rest, being the day after the Sabbath, was adopted as the “new Sabbath” with totally new meanings. The old Sabbath does not make anyone alive. Even our Lord was in the grave during the old Sabbath. On the new Sabbath our Lord was alive and gave us proofs of his life. He also gave us freedom from sin.–Compare John 20:19-20.
All this began on the first day of the Jewish week, what the Gentiles call “Sunday.”
From this the Catholic Church and most all Protestants observe Sunday, not as the Sabbath of the Mosaic Law–a Sabbath where no one comes to life–but the Sabbath of our Lord, a Sabbath where there is new life.–Matthew 12:18.
