Now it's personal

Whose authority did they need?

Where does it say that?

"then why not take your day of "rest" on Tuesday, or Friday, or Wednesday...? You argue that "Sunday" became the day to "commemorate the resurrection"..."

John 20:1 Early on the first day of the week, while it was still dark, Mary Magdalene went to the tomb and saw that the stone had been removed from the entrance. 2 So she came running to Simon Peter and the other disciple, the one Jesus loved, and said, “They have taken the Lord out of the tomb, and we don’t know where they have put him!”

John 20:19 On the evening of that first day of the week, when the disciples were together, with the doors locked for fear of the Jewish leaders, Jesus came and stood among them and said, “Peace be with you!”

Matthew 28: After the Sabbath, at dawn on the first day of the week, Mary Magdalene and the other Mary went to look at the tomb.

Luke: 24:1 On the first day of the week, very early in the morning, the women took the spices they had prepared and went to the tomb. 2 They found the stone rolled away from the tomb, 3 but when they entered, they did not find the body of the Lord Jesus. 4 While they were wondering about this, suddenly two men in clothes that gleamed like lightning stood beside them. 5 In their fright the women bowed down with their faces to the ground, but the men said to them, “Why do you look for the living among the dead? 6 He is not here; he has risen! Remember how he told you, while he was still with you in Galilee: 7 ‘The Son of Man must be delivered over to the hands of sinners, be crucified and on the third day be raised again.’ ” 8 Then they remembered his words.

Many people who are required to work on Sunday, do in fact choose other days. And good for them. They are still putting a day aside for rest. You're the one hung up on legalistic custom. Paul taught against that. The early believers met on the first day of the week to celebrate the Agape Feast, because they were in better position to know what day Jesus rose than you. The actual witnesses were alive and speaking to them at the time.

I'd love to know where in the New Testament it says to label everyone you disagree with as a pagan and condemn them to hell. I must've missed that one.

"Well, you know, there's the whole speaking from the fiery and smoky mountain thing..."

Who needs a bush when you've walked with God in the flesh? Luke says himself that there weren't enough books in the world to record all the teachings and deeds that Christ performed while he walked with them, so you don't know what you don't know about early customs and their legitimacy.

Colossians 2:16 Paul admonishes, "Therefore do no let anyone judge you by what you eat or drink, or with regard to a religious festival, a New Moon celebration or a Sabbath day."

Sabbath means rest. The Commandment doesn't say "Saturday" or "Sunday", only that you work 6 days and rest. The reason is given that God created the earth in 6 days and rested, and the other reason given is to remember the plight in Egypt where they were made to work everyday, hence, the day of rest is to be holy (set apart for something special) and a day of remembering God and how he delivered them from the Egyptians. At some point someone decreed that on such and such a day the work week will begin, but that wasn't God, and the work week is different across all cultures. Only the Jews sought to kill people for not recognizing their arbitrary days and dates. Jesus didn't come to reinforce their error, but to correct it.

The Jews are the ones who ascribed the actual day--based on calendars available at that time. Those calendars were flawed and lost days every year, and I'm pretty sure God didn't smite them for not knowing what day it really was. Our calendar today isn't even that precise and requires a leap year just to catch up. Days and names are just arbitrary terms used to measure the passing of time anyway. Legalists concern themselves with useless "days" and "customs" for the sake of control. Jesus himself didn't even keep the Sabbath to their strict specifications, but was condemned for something as simple as picking wheat, eating a snack and healing someone. He is known for "fulfilling the law", but that falls apart if he was bound to the Jewish interpretation of it. So it wasn't about having a specific day of the week so much as having a day of rest for reflection and worship. The Jews reflected on their means of deliverance from the Egyptians, while the early Christians reflected on the deliverance from the condemnation of sin, brought about by the death and resurrection of Jesus, who appeared to them on the "first day".

"They changed the "day of rest" from the Sabbath to Sunday on no authority but their own, to honor their pagan beliefs, and fooling billions in the process."

Um, the Apostles did this in the book of Acts. Did you just call the Apostles pagans?
