"I sincerely believe that if I received a COVID-19 vaccination, I would be committing an immoral act and grave sin. According to my faith, I would be prevented from receiving eternal life through Jesus Christ. I believe that receiving a COVID-19 vaccine would subject me to eternal torment in hell because of the grave sins of participating in abortion, partaking in fetal experimentation, partaking in the use of cells taken without consent (a violation of the image and likeness of God), ignoring the clearly expressed Will of God for my life and the lives of all faithful Orthodox Christians, and the grave sin of ignoring the express warnings of the Holy Spirit delivered through saints and elders not to partake of these injections, that taking these vaccines would be a grave sin of participating in demonic activity that could be leading to the Mark of the Beast, which is the ultimate rejection of the Kingdom of God leading to eternal damnation, and that I would be imbibing impurities that would violate the status of my body as a temple of the Holy Spirit. At the risk of my immortal soul, I must avoid the COVID-19 vaccine at all costs."
