I don’t believe like some rationalists do that the will and spirituality per se can be effected by anything physical. Certainly emotional and psychological conditions can be, but not the spiritual per se. In other words, I don’t believe in the underlying premise insinuated by some that spirituality is determined by genetics, i.e. don’t believe in the so-called God gene. Nor do I believe that the jab does anything to the immortal soul through a physical mechanism.
I do however believe that it’s a demonic sacrament of some kind to which is attached some kind of demonic activity and presence.
YES, I agree with this.
Some prots seem to believe that the physical jab totally changes your soul or something. That is ridiculous. It's a mortal sin, and once in mortal sin you lose savor for things spiritual. And I agree with your last sentence, that there is something of the demonic involved. The devil likes to ape God, so the devil has his own "infernal sacraments" of a sort: murder, fornication, and the like. Probably any sin is considered an act of worship.
Some times, physical things are "an outward sign used by Christ to give grace" like water during Baptism. God gives water that efficacy. Likewise, the devil can choose to enter someone after they ate a cursed piece of salted pork (true story! read your Catholic books and Lives of the Saints).
