True Christianity - as practiced by the disciples - has had a profoundly positive impact on the world. Counterfeit Christianity - which is false Christianity - has had a profoundly negative effect.
All organized religions have had a detrimental effect on the peace of our world. If people just had a simple faith with a personal relationship with God, then the whole world would benefit. Organised religions are man-made rules and dogmas which were originally used to control the masses in times of illiteracy and superstition. Today, people are squabbling and name-calling about which of these man-made rules is the "true faith". God must shake his head in total amazement at us all!
Bad.
Inquisitions.
Holy Wars.
Suppression of the spiritual techniques that Jesus himself taught.
Jesus said, "Even greater miracle than these shall you also do." So, Christians should all be walking around at least able to do miracles if the Church was real. I think the Church suppress info to prevent this, otherwise people would not need the Church anymore. Greedy Churches! The Good True Christianity is out there, just look somewhere else than a church.
When the churches literally ruled society, the human drama encompassed: (a) slavery; (b) the cruel subjection of women; (c) the most savage forms of legal punishment; (d) the absurd belief that kings ruled by divine right; (e) the daily imposition of physical abuse; (f) cold heartlessness for the sufferings of the poor; as well as (g) assorted pogroms ('ethnic cleansing' wars) between rival religions, capital punishment for literally hundreds of of fences, and countless other daily imposed moral outrages. . . . [i]t was the free-thinking, challenging work by people of conscience, who almost invariably had to defy the religious and political status quot of their times, that brought us out of such darkness
It is very sad and not promising at all, and it may lead to the end of mankind.
The whole concept of the christian faith is based on a continuous evolving fabrication through time mad by the European Man.
This faith was adopted by the Roman Empire and it is based on the Greek Mythology, and that way they were able to control the populous. They even invented the concept of divinity for Jesus.
The Roman Empire was destroyed from inside and caused the empire to split between the Eastern Greek Orthodox and Western Roman Catholic that became dominant over Europe.
The Catholic Church ruled Europe with an Iron Fist until the King of England needed to find a justifiable answer to divorce his Spanish queen, and take his cousin as his wife along with his bastard son.
As a result, war erupted between the Catholics and the new Church made by the British, the Protestants.
After 40 Years, the war between the Roman Catholics and the newly created Protestant Church that ended with Black Plague and reshaped Europe with the creation of other new churches, Crusade War on the Islamic Empire, age of colonization, Discovery of the South African Route that lead to slavery of Africans and Asians, Discovery of the Americans/Bahamas, Napoleon Bonaparte, Sykes & Picko Agreeement, WW1 & WW2, and the Global Market.
Continued to declare war on countries that are not Christians and fabricating accusations to justify a fabricated cause to a continued war.
Both.
Christ's ideology has a good effect on the world and people who try to follow his example contribute to that.
Religious brainwashing has a negative effect.
People who have no concept of a God find blind faith and God bother es an irritation and on a grander scale they have had a bad effect on the world because some Christians don't adhere to their leaders teachings.
