You are in denial of 1 Cor. 15:4 - not being spotted on the third day, but risen from the dead on the third day. Triumphant entry into Jerusalem was the fulfillment of Lamb selection day, Nissan 10, Sunday; Crucifixion the fulfillment of Passover, Nissan 14, Thursday, not Wednesday or Friday; third day from Thursday, Sunday.they are all tied to gather, They are the ONE WAY of the LORD.
There is NO command to assemble on sunday --- there is on the 7th Day.
there is no command to do any thing the churches do today. zero
There exist no scripture in the Old or the New stating Christ will be or was resurrected on the first day of the week.
The only verse you have, when the women got to the tomb before sunrise -- Christ had already left the tomb --- at this point there is no conformation as to when Christ was raised to eternal life. Thus it is only your opinion -- I use the Words of Christ.
there is zero proof in scripture, there is zero records of a resurrection in the dark on the first day of the week.
going back to that ONE WAY,
It is very unlikely you have been shown what Zechariah the prophet foretold what is coming after Christ is on earth,
every person on earth will keep the Feast of Tabernacles or be punished.
Read the entire chapter there is no doubt this is after His return to earth
16 And it shall come to pass, that every one that is left of all the nations which came against Jerusalem shall even go up from year to year to worship the King, the LORD of hosts, and to keep the feast of tabernacles.
17 And it shall be, that whoso will not come up of all the families of the earth unto Jerusalem to worship the King, the LORD of hosts, even upon them shall be no rain.
18 And if the family of Egypt go not up, and come not, that have no rain; there shall be the plague, wherewith the LORD will smite the heathen that come not up to keep the feast of tabernacles.
19 This shall be the punishment of Egypt, and the punishment -- of all nations -- that come not up to keep the feast of tabernacles.
For I delivered to you first of all that which I also received: that Christ died for our sins according to the Scriptures, and that He was buried, and that He rose again on the third day according to the Scriptures. (1 Cor. 15:3-4)
