Had Jesus meant that his Church should not keep the Sabbath, then a direct command to the effect could be expected. Would Jesus not, while He wanted the Sabbath no longer to be kept, have positively referred to the “new Day of Rest” the First Day of the week? He would! That or anything nearly of the sort Jesus never did – specifically NOT in the form of the claim of being Lord of the Sabbath or in the form of his resurrection. And that quite plainly protests that Jesus never imagined the Sabbath to be replaced or abrogated, but constantly had its improvement – through his own doing – in mind.
Quite the logic you have here. You argue from the standpoints of: a negative, of silence, and most of all "the imagination of Jesus," as if you could know what he imagines--how absurd!
What you don't do is base any of your arguments on Scripture. It is all speculative. They are just imaginative ideas--all your own prejudicial ideas that you have come up with. They have been affected more by your own "religion," culture, and up-bringing then by Scriptural study. You have presented me nothing of any substance that is based on Scripture.
There is no command given in the Bible to keep the Sabbath, at least not for Gentile believers.
There is no command for anyone to worship on the Sabbath--anywhere.
The Sabbath was meant for rest, not for worship. Worship and rest are not the same.
