"Greatest man in history, named Jesus" by itself is a false claim. In the Bible, what we take as "Jesus" is Ιησους in Greek (the language in which the New Testament was written). I-ei-s-o-u-sa would be its pronunciation. In every other place, beyond the Bible, that is translated as Joshua. In Hebrew, the same applies, though it is pronounced Y-e-sh-u-oa.
"Had no servants, yet they called him Master" is partially true, even if it was taken out of context. The word master used is the same as an apprentice would call their teacher - master. The word used is κύριος (kyrios). Masters of a trade never have servants, only apprentices. Theoretically, if the father, Joseph, was a carpenter, Joshua could have easily been considered a master carpenter.
"Had no degree, yet they called him Teacher" once again goes back to teacher. δάσκαλος (daskalos) is the word used, here, though it doesn't imply a master, just a more learned person. Well, no duh he had no degree; no person in that time period had a degree - they learned (the rich, anyway) were formally educated, everyone else was educated by a master of a trade (typically a family member, but not necessarily).
"Had no medicines, yet they called him Healer" is another statement of ignorance, as well as arrogance. They did have medicines back then, herbal in particular, that doctors still recommend to help you feel better or to prevent infection. Examples? Peppermint for upset stomachs. Chicken, honey, lemon for sore throats and coughs. Need I go on? I'm sure you're also asking in an exclamatory voice "WHAT ABOUT HEALING THE BLIND LOL!!!?!?!?!?!?!!!~!one" Simple. Who has heard of hypnosis? What about a somatoform (or conversion) disorder? Well, I shall endeavor to brighten the dim. Somatoform disorder - "is a mental disorder characterized by physical symptoms that suggest physical illness or injury - symptoms that cannot be explained fully by a general medical condition, direct effect of a substance, or attributable to another mental disorder (i.e. panic disorder).[1] The symptoms that result from a somatoform disorder are due to mental factors. In people who have a somatoform disorder, medical test results are either normal or do not explain the person's symptoms. Patients with this disorder often become worried about their health because the doctors are unable to find a cause for their health problems. Symptoms are sometimes similar to those of other illnesses and may last for several years.
Somatoform disorders are not the result of conscious malingering (fabricating or exaggerating symptoms for secondary motives) or factitious disorders (deliberately producing, feigning, or exaggerating symptoms) - sufferers perceive their plight as real. Additionally, a somatoform disorder should not be confused with the more specific diagnosis of a somatization disorder." n From Wikipedia, which was quoted almost directly from the official diagnosis manual (DSM) for psychiatric disorders. Essentially, you feel something that isn't there, usually because of an extreme emotions or sub-conscious that is trying to bring to your conscious mind (especially guilt). The example I was given in my Abnormal Psychology class was something like this - "A guy acted as a chant and meditation leader, and he would be holding a staff with a ball at the end that he would claim could heal people of their problems, then set up some fake examples by paying people to fake disease then 'heal' them with his staff and a little gibberish in Latin. After this, he would have people come forth. A person with a sore throat would come forward, he would place the staff at their throat and they would be 'healed'. Next, an older couple would come up, one of them being blind, he would place the staff between the blind man's eyes, and he would be 'healed'. A doubter of some repute as being knowledgeable about medicines and disease came the next gathering and proclaim that what the leader was false, but the leader said it wasn't and set out to prove it by calling forth another blind man. This blind man, though, doubted the leader now, and when the leader did his little ritual, the man was not healed, and people never came back to the leader."
"He had no army, yet kings feared Him" was more of a displacement of the fear. The kings (what kings? That area was controlled by the Roman Empire at that time, so no kings were present in that land, only Senators appointed by the Emperors Augustus and Tiberius) only feared the idea of him - the kings wanted peace in their land and to gather the tithes given by the peasants during the religious festivals. A religious leader with charisma was bound to rouse the rabble and stop people from giving tithes (think of the incident of Joshua throwing the tables over at the Temple). The Senators feared many people throughout the Empire's history, including their own family. Nothing special here, really.
"He had no army, but conquered the world" is an exaggeration. He didn't conquer anything himself, in person. Also, his followers sure didn't successfully spread his Word into Asia very well. Remember all of those Buddhists?
"He committed no crime, yet they crucified Him" is a statement of pure ignorance of Roman law. Roman law dictated that anyone not attending religious festivals or attempting to stop others, or otherwise interrupt would be fined and arrested. Repeat offenders could, depending on the severity, be killed or sent into one of the colosseums for sport. Another law was that anyone trying to cause an uprising against the Empire would be arrested and flogged for a moon cycle, with repeat offenders potentially being killed. These are the main two Roman laws Joshua broke - repeatedly.
"He was buried in a tomb, yet lives today" is another false translation. The word used here was σπήλαιο (stailaio), which translate, otherwise, into cave. Also, him being alive is false in all ways we define the term.
So, in summary, we are perpetuating a statement of faith about someone whose name we don't actually know, using poor translations of the words used without knowing anything that went on during that time period. Religion - the greatest zeitgeist ever created.
