Humans are a herd animal. It is in our genetics, our genes, our nature, to follow a pack leader. Religion was the method of establishing this pack leader well before we had any notion of ‘nation’ or ‘statehood’ or ‘ethnic identity’. All religions are founded in their basic concept based on this natural human herd instinct. And like any herd, the leadership is always determined by some violent confrontation between leadership contenders to determine which person will be the alpha, or dominant, leader. Unfortunately, humans tend to forget that we are animals in our nature, and behave just like all other animals, except that we are just a bit more intelligent than many other species and a lot more aggressively competitive.

So with this in mind, humans were bound by nature to have religion, and to be lead by a religious leader (before we invented statehood, after the Peace of Westphalia). Basically, the only choice humans had was ‘what religion’? it is a matter of which religion was the most aggressive, and after that factor, the most appealing. The ‘savior’ part made it ‘appealing’, but ‘aggression’ was still the major factor. Christianly may have been appealing before Constantine, but it was not aggressive until he brought the military power of the Roman Empire behind it.

‘Christianity’ and ‘the Roman Catholic Church’ are two very different things. Christianity had very little traction in the world until a certain Roman Emperor saw his empire in decline, realized that military power alone would not keep it strong. What he needed was a borderless, stateless religious empire, with this mythical God as his power source, so he appropriated the Christian religion, made himself the leader (Pope) of it, and used religion, not military power, to control the people. To this day, the Roman Empire and the power of the Roman Emperor to rule all mankind continues under the guise of the Holly Roman Catholic Church. It has very little to do with Jesus Christ, and everything to do with the perpetuation of the dominance of the Roman Empire and the dictatorial authority of the Roman Emperor.

The down votes prove the point. The Roman Catholic (Church) Empire is so pervasively insidious in the mass media, that they overwhelmingly down-vote any criticism of their empire in an attempt to force the algorithms into suppressing it from being seen.

I don’t understand the question. It does not compute. Before Jesus died, there were no vampires or zombies. People came back from the dead routinely. No reason, they were not vampires or zombies or anything else in particular, they were hallucinations, religious skullduggery, entertainers, and scam artist tools. After Jesus died, it became well known and commonly accepted that the ONLY person who came back from the dead was Jesus, so when people continued to come back from the dead, they had to be called something else besides ‘humans coming back from the dead’.

What exactly is an ‘instance’?
