No. Linguistically, the "Lord's Day" is exactly the same as the "Day of the Lord." That is not a day of the week but refers to the day of judgement and destruction at the end of the age.
Yes.
The Lord's Day refers to the 1st day of the week also known as the 8th day, I will quote what I had written again for you to read, take your time & take it in.
In the creation story in Genesis, God created everything in 6 days & on the 7th ELOHIM/GOD rested, 1 day is as a 1000yrs to Yehowah, & most believe we're around 6000yrs & Messiah shall return the 7000th yr which would represent rest/Shabbat the 1000yr reign with Messiah on thee earth, is there any books that mention such a thing? YES! An Apocrypha book of Barnabas, now if the 7000th yr is when Messiah is to come which is to be the 1000yr reign, then the 8000th yr will be the New Beginning, the 8th say was known as the first day also in some Apocrypha books, the day of Messiah's resurrection. Take a look at what this Apocrypha book says, & keep an open mind.
Chap. XV. — The False and the True Sabbath. Further,145 also, it is written concerning the Sabbath in the Decalogue which [the Lord] spoke, face to face, to Moses on Mount Sinai, “And sanctify ye the Sabbath of the Lord with clean hands and a pure heart.” (Exo_20:8; Deu_5:12) And He says in another place, “If my sons keep the Sabbath, then will I cause my mercy to rest upon them.” (Jer_17:24, Jer_17:25) The Sabbath is mentioned at the beginning of the creation [thus]: “And God made in six days the works of His hands, and made an end on the seventh day, and rested on it, and sanctified it.”146 Attend, my children, to the meaning of this expression, “He finished in six days.” This implieth that the Lord will finish all things in six thousand years, for a day is147 with Him a thousand years. And He Himself testifieth,148 saying, “Behold, to-day149 will be as a thousand years.” (Psa_90:4; 2Pe_3:8) Therefore, my children, in six days, that is, in six thousand years, all things will be finished. “And He rested on the seventh day.” This meaneth: when His Son, coming [again], shall destroy the time of the wicked man,150 and judge the ungodly, and change the sun, and the moon,151 and the stars, then shall He truly rest on the seventh day. Moreover, He says, “Thou shalt sanctify it with pure hands and a pure heart.” If, therefore, any one can now sanctify the day which God hath sanctified, except he is pure in heart in all things,152 we are deceived.153 Behold, therefore:154 certainly then one properly resting sanctifies it, when we ourselves, having received the promise, wickedness no longer existing, and all things having been made new by the Lord, shall be able to work righteousness.155 Then we shall be able to sanctify it, having been first sanctified ourselves.156 Further, He says to them, “Your new moons and your Sabbath I cannot endure.” (Isa_1:13) Ye perceive how He speaks: Your present Sabbaths are not acceptable to Me, but that is which I have made, [namely this,] when, giving rest to all things, I shall make a beginning of the eighth day, that is, a beginning of another world. Wherefore, also, we keep the eighth day with joyfulness, the day also on which Jesus rose again from the dead.157 And158 when He had manifested Himself, He ascended into the heavens. -- Epistle of Barnabas
This is exactly what you hear often how Yeshua will return in the 7000th yr, the only thing that has not been mentioned is the 8th day the 8000th yr the New Beginning, & how they kept both the Sabbath & Resurrection day as holy days. There're many other Apocrypha books that mention; the keeping of both the Sabbath & Lords Day which is the 1st day of the week Sunday in these Apocrypha books.
Wiki- In the first centuries, Sunday, being made a festival in honor of Christ's resurrection, received attention as a day of religious services and recreation, but seventh-day Sabbath rest (based on the Jewish Shabbat, because the earliest Christians were all Jews) was still observed by "almost all churches".[10][11] Often first-day worship (Sunday morning or Saturday night) was practiced alongside observance of seventh-day Sabbath rest[15] and was a widespread Christian tradition by the 2nd century, attested in patristic writings of the 2nd century;[16][17] over time, Sunday thus came to be known as Lord's Day. These early Christians believed that the resurrection and ascension of Christ signals the renewal of creation, making the day on which God accomplished it a day analogous to the first day of creation when God made the light. Some of these writers referred to Sunday as the "eighth day".
Wiki- The Eastern Orthodox Church distinguishes between "Sabbath" (Saturday) and "Lord's Day" (Sunday), and both continue to play a special role for the faithful. So Sunday keeping did not start with Rome, but was already being practiced by Jewish people in the 2nd Century.
8 represents a New Beginning in the bible which is like day 1 in creation, Elohim/God created the heavens & thee earth, God will then create the New Heavens & the New Earth in the 8000th yr, which will remain forever & ever!
Messiah also gives New Life to all who come to him & rest.
That makes total sense once you take of the Hebrew Roots thinking cap!
