Thanks. I can see your point, though I disagree with your implication. I know that many Christians erroneously think Sunday is the Sabbath and that it is therefore proper to worship (and rest) on Sunday. I look at Sunday worship as a convention, participation in which is not inherently wrong.
It is inherently wrong when we assume a pagan day of worship of the sun and then renounce the Sabbath day as no longer binding.
In fact, if you think about it, its blasphemy of the highest order. Opting to worship our God on a pagan day of worship of the Roman's Sun god, defending that as some do, and worse, in the process, denying the day of Sabbath as that day of worship the God of the Christians ordained as his day of rest that he created for us?
Worship on pagan's sun's day but denounce God's Sabbath day? Do we think God forgot what he instituted as his Sabbath? Do we think he doesn't realize what Rome's Sun worship day is?
