Even outside of the Christian churches the story of a man born some 2000 years ago that taught a revolutionary message of peace resonates! It resonates with inspiration to Asiatic peoples. It resonates with hope throughout Africa. It resonates with inspiration across Europe. In fact it is fair to say that there isn't a part of the world whose peoples are not at least minimally familiar with the life of this one single man born some 2000 years ago in an unremarkable town somewhere in what is now known as the middle east.
We therefore do not have to ask who this man is. Ask this question and any number of people will volunteer very similar answers: A prophet, a messenger, a teacher, a rabbi, the son of God, Savior, deliverer, messiah, God! Wait a minute did I just say God! That is right! This man of amazing influence is known to a large percentage of the world as God! He is worshipped as a living deity! Graven images are made portraying a human being often in a supine position with arms nailed extended on two intersecting pieces of wood. This object is then venerated as either the physical manifestation or representation of this human being, this man whom is worshipped as God!
Why do most Christians worship a human being? I guess the same question could be asked of Buddhist but any Buddhist will tell you that despite the alters and prayers and candles that what they do is not worship. Hard to believe right? Well Christians also have a similarly convoluted explanation. They say that this human existed before he was born in the form of a being that is separate yet the same as God and that it is this being that was born in human flesh and it is this reason why they worship a human as God!
But can a man be God? Interestingly enough the worship of this human being started inside a religion that taught that no physical representation of God should be made. A religion that taught that God was an ever present, all powerful and invisible force, one whose life force was in all creatures but that could not be contained. It, incase you want to know, did not teach that man could be God. This religion as you have already surmised was unique during those days.
In fact most religions of that time period believed in Gods becoming men or men becoming Gods. This type of belief was considered idolatry by the religion whom this man belonged too. Christian insist that this man claimed to be God but that would be a sin to the very religion that he belonged to and c certainly he couldn't have thought to himself that he having been born was the God of the religion he professed? Not unless he had been influenced by the religions around him! The other option is that he did not profess to be God. It could very well be that what he professed is that God spoke through him in a way that man had not experienced before and that this made him special enough to follow him.
But this is not good enough for those who worship human flesh. To such it is important to pray to a visible deity. It doesn't matter to them how unreal that concept might be. There is also an obvious danger besides idolatry in worshiping a human being, as if that wasn't bad enough. Humans are faulty and that means that any believable person saying they are this man-God could conceivably have millions of people led astray from the true God's commands. So why do most Christians worship a human being?
