Sunday worship, a novel doctrine not found in the Bible
Yes, God called for a holy gathering on Saturday but God did not call the gathering for worship in the Temple where one was made to believe it was for worship. If the Temple was for worship ( house of prayer)and the Sabbath was for worship, Jesus puts an end to local worship during His conversation with the Samaritan woman.
John 4:19-24 YLT
(19) The woman saith to him, `Sir, I perceive that thou art a prophet;
(20) our fathers in this mountain did worship, and ye--ye say that in Jerusalem is the place where it behoveth to worship.'
(21) Jesus saith to her, `Woman, believe me, that there doth come an hour, when neither in this mountain, nor in Jerusalem, shall ye worship the Father;
(22) ye worship what ye have not known; we worship what we have known, because the salvation is of the Jews;
(23) but, there cometh an hour, and it now is, when the true worshipers will worship the Father in spirit and truth, for the Father also doth seek such to worship him;
(24) God is a Spirit, and those worshiping Him, in spirit and truth it doth behove to worship.'
Jesus did not speak of a particular day or place to worship. Worship had been upgraded, independent of a particular day or physical location. There is no longer a requirement to attend any particular church to worship anywhere in the planet from the perspective of Jesus, if the purpose of the gathering is for worship. Do you get that point? Thus, there cannot be any pulpit where a preacher could stand on a Sunday to smear or calumniate the Sabbath day with empty (verse 23) doctrinal rants attempting to validate Sunday worship because there is no nemesis Saturday worship.
Casually, that "controversy" about which day is the worship day can be settled by Judaism. And, technically, Saturday has nothing to do with worshiping, a fact that should have been self-evident.
If the question involves the day of the week, then Judaism from which Christianity springs forth settles the matter, it is Saturday. From the creation of the world to the death of the last Jews who spread out Judaism from the perspective of Jesus Christ, no one from the Jewish heritage worships Jehovah God on Sunday. It has always been on their Saturday day, if, for argument sake, we may treat the Sabbath as a day of worship. Thus, it is kind of mindboggling that any post Apostolic evangelist, preacher, pastor, or priest teaches in any way that Sunday is the day of worship. Which Jew who is in the camp that still rejects Jesus Christ as the Messiah could make the case by any reasoning that Sunday is the worship day, supplanting Saturday? In religion anything can be taught but it is inconceivable that a Jew would give much credence to Christianity condescending the Sabbath day of Jehovah God, of Moses, of Jesus, of the Apostles, in favor of Sunday. If the seventh day Saturday Sabbath had been made obsolete by Jesus Christ who, paradoxically, while He was still alive, says that He is the owner of the Sabbath, why is it that the foundation of Sunday seeks to duplicate and further what the Jewish heritage, Jesus Christ and His Apostles included, had been doing since eternity on the Sabbath day? Why would the Sabbath day be abolished to give way to Sunday worship? Colossians 2:16 does not abolish the Saturday day even if the Sabbath day was a day of worship. Read and meditate the verses on the institution of the Sabbath in the book of Genesis and ask yourself if there can ever be any argument against it.
Where in the Bible do we read that Jehovah God no longer chooses Saturday? Where is the command from Jesus or His Apostles to choose Sunday instead of Saturday? Nowhere.
The other aspect of the "controversy" about the correct day of worship that might not have been addressed is whether God instituted or envisioned the seventh day Sabbath as a day of worship. So, let us consider what is written about the first Sabbath day in Genesis 2:1-3.
Why must we keep having a holy convocation on the Sabbath day, Saturday?
To rest and to be obedient in the spirit of Matthew 5:17-19 because Jesus says that He only fulfilled what was fulfillable and that not one jot had been discarded in the Law or the Prophets.
