So most of the religious belief systems have an Apocalypse figures who will come to earth and put sinners/non-believers to sword. Give the present religious situation we can safely say more than 2/3 rd's of the human population would be non-believers to any given deity. So let us suppose a random avatar/messenger of god/child of god/prophet of god/incarnation of god appears tomorrow with a huge sword and starts committing a genocide of most of earth's population,how do we non-believers counter it? . Here are some scenarios 1) The deity has a unenchanted sword and moves with normal speed. : Spoiler : Since this figure has no ranged attacks air attacks could be effective. Unless of course he/she can force throw the sword in a Jedi manner. Then I guess we need to take advantage of his/her normal mobility and have the forces constantly at the move sniping him/her. We can even find who are the true believers and use them as meat shields,since he/she can't hurt them. Since all religious followers might not be "true believers " according to the religious. We might need to water-board all the religious adherents and find which of them are true believers and use them. 2) The diety has a enchanted sword and moves with normal speed : Spoiler : It could be the deity has a magical sword with a single sword swipe can change weather phenomena causing floods earthquakes and tsunamis . We might need to determine what causes his/her sword to work. If it is by EM waves we might use a jammer to prevent it from working. We might need our true believers meat shields while we analyse the working of the sword from a distance. 3) The diety has an unenchanted sword and moves with very high speed: Spoiler : If the diety moves with a huge speed(almost speed of light) appearing wherever he wants (appears like teleportation) . Prepare some type of armor made of material stronger than iron/steel which swords typically are made of. Or maybe stay in enclosures/bunkers made of that material . 4) The diety has an enchanted sword as well as moves with a high speed: Spoiler : We are screwed. There's no way to react with instant teleportation like movements and armor piercing enchantments . Being in a different continent does not help either since some of then can walk on water ,or ask ocean itself to make a path for them to move. There is one loophole we can exploit though. All these deities described in different holy books appear only on earth for the purging . So if we can move a substantial amount of people to a colony on mars they can escape the genocide. Whatever form the deity figure appears though it's important thought to keep a updated list of true believers for each faith ready for an emergency . Updates could typically be done over a year or half-year depending on how much time it takes for the devil to corrupt a believer. So what are your action plans and suggestions on fighting the apocalypse.
