I have yet to meet a modern Catholic or many other Christians of any division that takes this warning literally. IF Christ had already foretold all things, before the so called new testament got placed upon plant fibers or animal skins and even Peter taught, then few will escape that first tribulation of deception.
The majority of Christians completely ignore the key of David, but, again God did say He would send a famine of hearing the words of the LORD GOD.
Some in more recent days twisted Paul's instruction on where those that have already passed through this flesh age journey are, into meaning a security blanket of gonna be gone before the bad stuff happens. I cannot get the rapturites to correlate the idea that Christ is coming here, to God's green earth to set up His Kingdom. The only Christians of whatever divisions/sects to escape the tribulation of deception are those Christ and Paul describe were elected ‘before the foundation of this world’ (age), that are still walking in the flesh body when the sugar daddy gets dumped out of heaven playing Jesus. Nobody in a flesh body can claim they will still be here in the flesh when that specific event takes place.
Rome's doctrine has it own security blanket named Mary. It was not Mary weeping for her children, it was Rachel, Matthew 2:18. But according to Catholic doctrine Rachel is not important enough to even be acknowledged, let alone studied to understand why she would have so been particularly mentioned in the so called New Testament. Just plain strange.
There is but one Creator and His intent was that all His children be saved. Salvation is a constant subject throughout the old testament, but, modern Christians too are so wrapped up in which church mantle is closer to Jesus. Was not that question even asked of Jesus?
Now to be absolutely clear nothing I wrote above is about my judgment of any soul to any future. Rather an admonition that it is a total waste of Christian time to be arguing over who sits closest to Jesus.
No doubt there is huge deception out there. I came across, on another site, a few months ago some poster discussing some “serpent seed doctrine.” Bizarre truly and of course such doctrines are stared by some man with a new or “refreshed” vision.
