Ir-regardless of "Who Killed The Messiah,...... Per His Teachings,..... He will return only once, and at the end of "The Time of Yacob's Trouble/ The Tribulation".
And,.... He will not be gathering, at the "Resurrection", anyone that refuses His Teachings, and His Covenant.
The Messiah absolutely kept the Sabbaths listed in Lev. 23:1-44, & That is stated repeatedly in The New Testament.
"Christianity" keeps the First Day of the Week Sunday Sabbath, & the Pagan Holidays honored by Catholicism.
"Christianity" largely claims that "The Law was nailed to the Cross", where The Messiah, & His Apostles never stated that. And yet "Christianity" zealously proclaims that at any minute they will be "Raptured Up".
Here, is what "Rapture ready Christianity" will do, once it realizes The tRuth.:
2Th 2:1 Now, brothers, concerning the coming of our Lord Jesus Christ, and our gathering together to him, we ask you
2Th 2:2 not to be quickly shaken in your mind, and not be troubled, either by spirit, or by word, or by letter as if from us, saying that the day of Christ has already come.
2Th 2:3 Let no one deceive you in any way. For it will not be, unless the rebellion comes first, and the man of sin is revealed, the son of destruction,
2Th 2:4 he who opposes and exalts himself against all that is called God or that is worshiped; so that he sits as God in the temple of God, setting himself up as God.
2Th 2:5 Don’t you remember that, when I was still with you, I told you these things?
2Th 2:6 Now you know what is restraining him, to the end that he may be revealed in his own season.
2Th 2:7 For the mystery of lawlessness already works. Only there is one who restrains now, until he is taken out of the way.
2Th 2:8 Then the lawless one will be revealed, whom the Lord will kill with the breath of his mouth, and destroy by the manifestation of his coming;
2Th 2:9 even he whose coming is according to the working of Satan with all power and signs and lying wonders,
2Th 2:10 and with all deception of wickedness for those who are being lost, because they didn’t receive the love of the truth, that they might be saved.
2Th 2:11 Because of this, God sends them a working of error, that they should believe a lie;
2Th 2:12 that they all might be judged who didn’t believe the truth, but had pleasure in unrighteousness.
Those who Believed that they were Worthy of being "Raptured Up", once Physical Reality dawns upon them,......They will quickly give up the "Faith" that they proclaimed, and in order to Save their Physical Lives,... They will Honor, & Give their Allegiance to the 'Beast"/"Little Horn".
Mat_10:38 He who doesn’t take his cross and follow after me, isn’t worthy of me.
Mat_16:24 Then Jesus said to his disciples, “If anyone desires to come after me, let him deny himself, and take up his cross, and follow me.
How is it, that the "Believers of The Way", that proved that they were Willing to "Take up their Cross", during the times of the Roman Emperors, such as Nero, & Caligula,....... Did not get "Raptured Up"?????
Many a Historical Record vividly describes these "Believers" being Horribly put to death in the Roman Arenas!
That "True Faith", of, & in, The Resurrected Messiah & His "Way", spread across the Roman Empire like a California Forest Fire, and,..... Constantine the Great, realizing that it could not be stopped, even with Severe Persecution, & the Pain of Death, cunningly merged his Pagan Beliefs in the Pagan Goddess Mithra, with beliefs of the "Way", and formed the Pagan State Religion of "Catholicism".
"Christianity", starting at the "Reformation", came out of that Pagan State Religion, and that evolved in to thousands of widely different, & heretical beliefs, that are still "Rooted in Catholicism".
Honoring even "One Micron" of those Pagan Beliefs, will stop one from being part of the "Harvest/Gathering" of the "Saints"/"Chosen Ones"/"Elect", & Those who are called "My People".
If One is unwilling to "Pick up their Cross", they will not enter The Kingdom of Heaven, here on Earth.
