I believe it’s fair to say that all Christians recognize the incredible theological transition that happened between the Old and the New Testament. For example, Article 10 in
The Millerite Adventist Creed says:
Many of God's Old Testament laws (
Exodus 12:1-28,
Leviticus 16) and covenants (
Genesis 17:1-14,
Exodus 31:12-18,
Exodus 34:28,
Deuteronomy 4:13,
Deuteronomy 9:9,11,
Ezekiel 20:12,20) emphasized symbolic rites that foreshadowed a new paradigm of unexpected spiritual truths (
Luke 22:14-20,
Matthew 26:26-29,
Luke 12:1,
Mark 8:15,
Romans 2:29,
Colossians 2:11-12,
1 Corinthians 5:6-8,
1 Peter 3:21,
Revelation 14:7, etc.).
Examples
Indisputably, God once said,
"My covenant in your flesh is to be an everlasting covenant" (Genesis 17:1-14). And the Sabbath command seems just as inviolable from an Old Testament perspective. But the New Testament clearly spiritualizes and reinterprets their original meanings.
Romans 2:29
"But he is a Jew who is one inwardly; and circumcision is that which is of the heart, by the Spirit, not by the letter; and his praise is not from men, but from God."
Likewise, the Sabbath is interpreted in the New Testament (
Hebrews 4:9) as a type of God's rest that we should enter into 24/seven.
Hebrews 4:1-3,10-11
Therefore, let us fear if, while a promise remains of entering His rest, any one of you may seem to have come short of it. 2 For indeed we have had good news preached to us, just as they also; but the word they heard did not profit them, because it was not united by faith in those who heard. 3 For we who have believed enter that rest ...
10 For the one who has entered His rest has himself also rested from his works, as God did from His. 11 Therefore let us be diligent to enter that rest, so that no one will fall, through following the same example of disobedience.
What is surprising and irrefutable (because of
Shubert's International Date Line Theorem) is that it's impossible to define the Sabbath day on a round planet. So the unmistakable conclusion seems to be that God purposely planned and inserted obsolescence into the Old Covenant.
