No. You are under a strong delusion. All days are days the Lord has made. The 7th day Sabbath is a day the Lord set apart, and it is a special day, binding in the covenant with Israel (adopted as a tradition or custom for all to gather in one place such as a synagogue, only during the Babylonian captivity, never before, but nowhere commanded).
It is NEVER called "the Lord's day" anywhere in the scriptures and certainly in none of the ones you have posted...this is eisegesis not exegesis. The first day, the day of the resurrection of Christ, became known as the Lord's day and was taught to be such, by the Apostles (who I believe know better than you) to all those they appointed as leaders in the churches they founded.
This is bore out by the fact that no matter where there was a local church and no matter which Apostle founded it, they all taught the same doctrine, and all who write tell us that the day of the resurrection is the Lord's day...a first or eighth day following the 7th day Sabbath (not replacing it) and "Sunday" or the day of the sun, has NOTHING to do with it (that it merely coincidental since Rome ruled the empire and called it that). But I am always confused by modern Sabbaterians in this regard, if Sabbath keeping be so important to you, why do you violate the Torah regarding it?
