Vaccine passports or vaccines in general are not the mark of the beast.

The mark of the beast is taken with the full understanding that you are following satan. You must declare this to receive the mark. You have to denounce God. This is clear as day in the Bible. Taking a vaccine (which there is no way I personally will) to protect yourself or someone else (supposedly) is nothing close to taking the mark. You will know it is the mark of satan and it will be your choice to take it. Spoiler-God wins. I would pass if I were you.

I would not take the vaccine because it is my understanding the microchip in the vaccine can alter me in ways so I might denounce God, because the chip may alter me enough that I lose my Soul connection to Source.

Don't let that mumbo jumbo stuff scare you. They can never take away your connection to God, only you can do that. Maybe they can alter your body but your soul belongs to God and they can't get anywhere near it unless you give it to them. You can never be cut off from God, the Bible tells you so. Vaccine or no vaccine he will never leave your side.
