first off, there is no Scripture anywhere that even suggests Sunday is the Lord's day.
The Messiah said, not one jot or one tittle would pass from the law, so you would think if one of the ten commandments was to be changed, there would be a clear directive in Scripture. (however, we know that He does not change).
As far as the documents you referred to, I have seen a few, but a lot more on the conspiracy to change the day.
I was in a Sun-day church for many years, and I still have a lot of friends and family there. Just not for me now that I know better.
It is a matter of historical record that Sunday worship began early in the history of the church - well before Constantine, in fact.
This is not in dispute but it is not, by itself, proof that we should be doing this or not.
What is in dispute is the argument disciplemike is putting forward.
He claims that the law has not changed (this is in fact true) as the argument for telling us (believers) that we are obligated to obey the law in every respect (this is not true).
The reason that the second assertion does not follow the first assertion is very simple:
Disciplemike will hate me for saying this but through the sacrifice on the cross Christ Jesus fulfilled the law in every respect on our behalf.
We accept this reality by grace through faith.
The law has not passed away but believers in Christ are no longer subject to its requirements.
Our salvation and spiritual future does not depend on obeying the law on every point, or any point.
This forum is replete with threads asserting that by us claiming that the law has no hold on us that Christians then become lawless reprobates.
This is not so!
Because we are not under the law we are free from the dictates of the law.
What this means is that we are no longer limited by the minimum requirements of the law as this dictates to our behaviour.
Instead we are free to love God without restriction and to behave and to do works in ways that the law can never legislate.
In Christ we are free to love and free to do much more than the law could ever enforce.
The basis of this is our love relationship with God.
Our motivation is not fear of the consequences of law, no, we are motivated by our love of God, free from any of the limiting dictates of the law.
Disciplemike has been deluging this forum with thread after thread, all with the same question:
Are Christians obliged to obey Levitical law?
As laid out above the answer to this is an emphatic NO!
No doubt disciplemike will vigorously defend his position and will also continue to post new thread after new thread all essentially, asking the same question.
However the answer to each question is the same: Christians are not under Levitical law - simple as that!
