Yes, they are losing their cool, and in their just-started hunt of monsters, they may indeed become monsters, too.
I certainly don’t like the idea/page of Jesus aborted, and no Christian would, but the assault by the spirit of Antichristwill be Jesus Himself - the real target here. Jesus said the spirit of Antichrist as well as the person of Antichrist will go after all that the Son is for before Jesus Christ returns. Antichrist’s goal is to go against Jesus Christ and His teachings, not Mary.
Clarification: there is a reason why Jesus,, Paul and the Apostle John reference the Antichrist as a person, and speak also of the spirit or attitude of antichrist that will be quite pernicious in the last days before He returns.
Notice it is the Antichrist spoken of in the Bible, and not the Antimary.....
Besides the idea is as ludicrous as the prophets of Baal thinking they could prevail (hey I’m a poet and don’t know it). If God is with us who can be against us. They are not going to be able to stop Christ. What we CAN do, and it does not matter what the shingle outside the church door says, it goes for all, is to clothe ourselves in Christ. Let Him be our strength, our energy. He is bent on saving what is possible to save. The fury of Satan? Christ laughs at it. The devil was whipped when Jesus was flogged.
