Here's correction for your false doctrine:
Sundays - Why we Observe
Jesus was raised from the dead on Sunday which is Pentecost (Mark 16:2, Luke 24:1, John 20:1)
We see in Acts chapter 2 that the first church service was on Sunday (the day of Pentecost they were all with one accord in one place and received the outpouring of the Holy Ghost). And, the first public evangelism meeting was also held on Sunday out in the street after the Holy Ghost was poured out in the upper room (Acts 2:14-36)
Acts 20:7
The first day of the week, the Apostles came together to break bread
The Acts of the Apostles is the second book attributed to Luke, I believe written about 80-90 A.D., we now come to one of the most frequently quoted verses of Paul to support the false teaching of the sacredness of Sunday: (Acts: 20: 7)
And upon the first day of the week, when the disciples came together to break bread, Paul preached unto them, ready to depart on the morrow; and continued his speech until midnight. Now let’s take a close look at this verse and dissect it a little. Notice Paul continued his speech until midnight! It was after sunset, but prior to midnight.
The first day of the week in biblical times did not begin at midnight, as men begin it today.
The Lord’s days begin and end at evening (sunset). (Gen. 1:5) And God called the light Day, and the darkness he called Night. And the
evening and the morning were the first. All biblical days began and ended at sunset. Throughout the Roman world at that time, and for a few hundred years afterward, days began and ended at sunset. The practice of beginning the new day at midnight was started much later.
So this meeting, and Paul’s preaching, took place during the time that we now
call Saturday night. Remember when dealing with the Lord’s days the
evening comes first. If you read more than just that one verse you would see what actually happen. Paul’s companions were engaged in the labor of rowing and sailing a boat while Paul was preaching that
Saturday night and early Sunday. They had set sail Saturday night, after the sabbath had ended. Paul remained behind for one more farewell sermon.
Then at day break Sunday morning, Paul set afoot, walking from Tro’-as to As’-sos to meet the ship. So actually Paul left Sunday Morning, but this verse (Acts: 20:7) says nothing about a change of the Lord’s Holy Sabbath day. And the term “break bread” simply means to eat, so every time Paul ate he broke bread, search it out for your self, the bible tells you to; (1Thess. 5:21)
Prove all things; hold fast that which is good.
1 Corinthians 16:2
Upon the first day of the week let every one of you lay by him in store, as God hath prospered him
Colossians 2:16,17 Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath days: Which are a shadow of things to come; but the body is of Christ.
Why follow the shadow of things that were to come after Jesus has arrived where we can join Him in The feast of First Fruits? Let no man therefore judge you concerning not observing Saturday sabbath seeing it's not a requirement given in the New Testament for salvation!
The Lord instructed the Israelites, “You shall count seven weeks for yourself; begin to count the seven weeks from the time you begin to put the sickle to the grain” (Deuteronomy 16:9). The word Pentecost means fifty, and it comes fifty days from the feast of First Fruits (Leviticus 23:10–11, 15–17). The feast of First Fruits was to occur on the day after the Sabbath (verse 11), which was always the Sunday of Passover week. Pentecost, then, was the day after the seventh following Sabbath (verses 15–16), which would be the fiftieth day after First Fruits and also falls on a Sunday.
In Leviticus, 23rd Chapter the Sabbath day and the High Holy Days which begin I believe on the new moon. Are the feast of the Lord's. These days are to be observe in their season. In Colossians 2:16-17, "
Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath days. Which are a shadow of things to come; but the body is of Christ. These feast days are the plans of God, they represent the future, with example from the past. All Holy Days are not to eat or drink, such as the atonement, but still to be observe. So this is actually what a person would say to someone who do not keep these feast day of the Lord, if they were judging them on those High and Holy Sabbath days, they were keeping. They would quoted Colossians 2: 16-17. So if you keep the first day of the week, Sunday, Easter and Christmas Paganism, then it makes no sense to use this verse. You cannot worship other days and God’s, that’s not written in the Bible to do, and then use the Bible to justify it. So if you keep another day thats not written in the Bible, then you are doing something on your own, thus it would really be contradictorily.
Jesus died on the Friday of Passover week and had to be buried hastily before sunset, which was when the Sabbath began. His body remained in the sepulcher throughout the Sabbath day, but on that Sunday morning, when the priest was to offer the First Fruits offering in the Temple, Christ arose from the dead as the first fruits of them that slept (I Corinthians 15:20). For forty days, Jesus appeared to His disciples and then ascended into Heaven. Ten days later, the Sunday of the Feast of Pentecost, the Holy Spirit descended upon the believers in Jerusalem.
According to tradition, if Jesus had died on Friday, He would have been in the grave Friday night, Saturday day and Saturday night. One would not count Sunday because in John (20:1) it states that the 1st day of the week which is Sunday, Mary came to the grave site when it was still dark. In Luke (24:1-6) They find that the stone which was placed in front of the sepulcher had been removed and an angel tells them that Jesus had already risen.
Jesus was always being inquired of by the Jews for a sign. He gave them one in reference to His death and resurrection. He told them that just like Jonas, He would be in the earth 3 days and 3 nights. In the Gospel of John Jesus again gave the Jews a sign by telling them if this temple was destroyed He would raise it up in 3 days. Jesus was referring to His body.
(Matthew 12:38) Then certain of the scribes and of the Pharisees answered, saying, Master, we would see a sign from thee. 39 But he answered and said unto them,
An evil and adulterous generation seeketh after a sign; and there shall no sign be given to it, but the sign of the prophet Jonas: 40
For as Jonas was three days and three nights in the whale's belly; so shall the Son of man be three days and three nights in the heart of the earth.
Let's take another look at it (John 2:18) Then answered the Jews and said unto him, “What sign shewest thou unto us, seeing that thou doest these things?” (19) Jesus answered and said unto them,
Destroy this temple, and in three days I will raise it up. (20) Then said the Jews, Forty and six years was this temple in building, and wilt thou rear it up in three days? (21) But he spake of the temple of his body.
Jesus makes it clear the time between His death and resurrection would be 3 days and 3 nights. Can't get three days and three night from Good Friday to Sunday.
Now lets take a look at; (Acts 13:13-15, 42, 44) (v.13) Now when Paul and his company loosed from Pa’-phus, they came to Per’-ga in Pam-phyl’-I-a: and John departing from them returned to Jerusalem. (v.14) But when they departed from Per’-ga, they came to An’-ti-och in Pi-sid’-I-a, and went into the synagogue on the sabbath day, and sat down. Paul went into the church (synagogue) on the sabbath day the seventh day not the first day (Sunday). (v.15)
And after the reading of the law and the prophets the rulers of the synagogue sent unto them, saying, Ye men and brethren, if ye have any word of exhortation for the people, say on. (v.42)
And when the Jews were gone out of the synagogue, the Gentiles besought that these words might be preached to them the next sabbath.
The Gentiles didn’t asked Paul to come preach us something different next Sunday. They wanted Paul to preach to them the same thing that he taught the Jews, the next sabbath. Even the Gentiles knew that if they were going to serve the same God that Paul and the Jews (Israelites) served that they would have to serve him on the day that God had set up. (v.42)
And the next sabbath day came almost the whole city together to hear the word of God. Not the next Sunday but the next sabbath.
