Were Jesus's Teachings Perverted?

Jesus Christ's real name was Immanuel (and "Yahushuah"(Joshua) or "Esu").
"they shall call his name Emmanuel, which being interpreted is, God with us". Matthew 1:23, previously "a virgin shall conceive, and bear a son, and shall call his name Immanuel" Isaiah 7:14.
Paul (who was no saint) renamed him Jesus Christ. King James followed this in translating Yahushuah to "Jesus".
Paul, and later Roman Emperor Constantine through the Councils of Nicea and Constantinople, succeeded in hiding and perverting the actual teachings of Esu Immanuel (Jesus Christ).
As just one example, Esu worshipped God daily, and especially on Sabbath. Some, not most, followers of Esu worshipped God on Sunday to commemorate Esu's Resurrection on Easter Sunday. "in 321, in a move to spite Jews and accommodate Christianity with prevailing pagan ways, Constantine made the day of Sol Invictus a holy day and a day of rest for the Christians -- Sunday." (fsmitha.com), then he got the Council of Nicea to vote to force all Christians to worship on Sunday. I don't think Jesus would have agreed.
Understand that the Council of Nicea succeeded in voting the way they did only after punching out the key opponent, who would have tied the vote.

Also, in Matthew 5:17, Esu states: "Think not that I have come to abolish the Law and the Prophets; I have come not to abolish them but to fulfill them..." and Luke 16:17 "easier for heaven and earth to pass, than one tittle of the law to fail". Paul said Christians no longer had to obey God's laws. Romans 10:4 "Christ is the end of law for righteousness", Romans 6:14 "ye are not under the law, but under grace", Galations 5:18 "If ye be led by the Spirit, ye are not under the law", 1 Timothy 1:9 "law is not made for a righteos man",
One of the earliest writings detailing the teachings and daily activities of Esu/Jesus is the Essene Gospel of Peace (venerated by the Eastern Orthodox Church, hidden in archives by the Roman Catholic Church).
John the Baptist was an Essene. Jesus and John were related. Jesus learned from Essenes (and is wrongly claimed by some to be its "Master"). Compare the Dead Sea Scrolls to Essene Gospel of Peace and you will see their emphasis on multiple daily meditations and raw food are also in Esu's teachings. The Essenes were much stricter by the book than Esu, and if he had been a member he would have probably been excommunicated, because he went by the spirit instead of the word. (e.g. saving someone on Sabbath). (See also Dead Sea Scrolls and Qumran.com).
The 4 Gospels, Matthew, Mark, Luke and John were all written much later, closer to 200 A.D. Compare their source material "Q" at Q = Origin of later Gospels

The Gnostic Writings at Nag Hamadi! show a deeper implementation of Esu's teachings. Gnosticism teaches us to go within and get direct answers from God. In many ways, this is similar to the original (non-religion) of Gautama Buddha, who taught everyone to stop listening to priests and go within to find the truth. These teachings are still preserved in Thailand and Laos by "Theraveda Buddhists" (theraveda = true way). The rest of the Buddhist world spreads the perverted "Mahayana Buddhism", which claims Buddha to be a God.
Esu wasn't lucky enough to keep followers on the true way after his death: the Roman Catholics declared anyone that didn't believe as they dictated to be heretics, and sometimes led crusades to annihilate them. The Cathars of Southern France, who called themselves "bons chretiens" (good christians) were annihilated in a crusade directed by the Catholic Pope. They were Gnostics that led such exemplary lives that many of the Templars sent to annihilate them joined them at the last moment, preferring to die with these noble followers than continue to help kill them.
Most later religious history labels the Cathars as Manichean Heretics.
The Church hid Jesus' Words: Check the Gospel of Thomas (from the Gnostic writings): 1, 2, 3&4,5+
Watch the Movie "STIGMATA"! More
(In "Stigmata", Gospel of Thomas: This scroll was allegedly written by Jesus just after the last supper. The movie is about 3 men who were translating the text for the Catholic Church. When the Church started to see what it was, it kicked out two of the men and the other one took the text and spent his life translating it. After the movie ended, there was a scrolling text before the credits, saying that in 1945, a text had been found near the dead sea that was thought to be the writings of Jesus, and that the Catholic Church tried to hide it, and now denounces it as heresy. This Gospel scroll states that God is not in any physical place, but is IN YOU. The Church did not want people to become less dependant on Church buildings.)

Paul was the one that renamed Esu Immanuel as Jesus Christ.
Paul/Saul was a Roman Citizen that claimed to be a Pharisee, son of a Pharisee.
Saul was born in Tarsus, Cicilia (neas Syria and Phoenicia,
Saul became a Roman Soldier in Jerusalem to control the native Jews.
Many claim that his efforts were among those that got Esu crucified.
Paul/Saul persecuted Christians until he suddenly claimed he received a vision.
Thomas Jefferson said "Paul was the first corrupter of the doctrines of Jesus."
Thomas hardy said "the new testament was less a Christiad than a Pauliad."
Paul/Saul wrote almost 2/3 of the New Testament.
Judas Iscariot betrayed Esu Immanuel with a kiss for 30 pieces of silver.
Some say that Judas was caretaker of the writings of the teachings of Esu, and sold them for 70 pieces of silver to the cohorts of Saul.
Some also say that Saul was hired by Rome to keep track of and thwart Esu and his followers, and that he did this by taking over Christianity and redirecting it.
Paul wrongfully called himself an Apostle to get a title to take over Christianity.
Esu Immanuel said in Matt 5:17: "Think not that I have come to abolish the Law and the prophets; I have come not to abolish them but to fulfill them...".

In the Dead Sea Scrolls, the Essenes talk of a "Liar" and a "Spouter of Lies". Some say that this applied to Saul of Tarsus, a Pharisee that lied to spread the power of Rome at the expense of local Jews, including Esu. Paul appears to have taken over shortly after Esu's death, and started writing his epistles about 50-60 AD. By contrast, Matthew, Mark, Luke and John were not written until close to 200 AD.
The Essene Gospel of Peace more closely reflects the actual day-to-day teachings of Jesus/Esu Emmanuel. (The Essene Gospel of Peace is accepted by the Eastern Orthodox Church. The Old Slavonic translations are in the Royal Archives of the Habsburgs, in Austria, but the original Aramaic intentionally stays hidden in the archives of the Roman Catholic Church.)

Other Questions

The council debated whether Christ was divine or whether he was simply a human tool of God. Constantine took the position that Christ was divine. Eusebius took the opposing position, along with 200 other bishops, that Christ was not divine. The bishops were asked to express their views on the subject and soon realized that disagreement with the emperor's view would lead to dire consequences. Many of them eventually turned silent. At the conclusion of the debates two of them remained adamant that Christ was not divine. Constantine declared them banished and excommunicated. Incredibly, the council finally settled the matter by voting. It declared that Christ was divine. And so billions of Christians, over the centuries, have been taught that Christ is divine, not based on fact, but based on a vote. If the Council of Nicea had voted differently, then the faithful would not know of Christ as divine. xlibris.com

From ejm.tripod.com/who_wrote_bible.htm:
Now let's turn to a reference on page 18 and 19 of The Encyclopedia of Biblical Errancy by Dennis McKinsey (quoting from Schmuel Golding's Biblical Polemics Newsletter):
"The New Testament was not written by any of the disciples of Jesus nor by persons who even lived in that era. ...When the church fathers compiled the N.T. in the yr. 397, they collected all the writings they could find and managed them as they pleased. They decided by vote which of the books out of the collection they had made should be the word of God and which shouldn't. They rejected several, they voted others to be doubtful, and those books that had a majority of votes were voted to be the word of God. Had they voted otherwise, all the people since calling themselves Christians would have believed otherwise. For the belief of one comes from the vote of the other."
Going on- "It is important to note the key concept here is that the Bible was put together by a group of men who met, went through a collection of writings, and chose through voting those that are deemed to be divinely inspired. Many of them wound up on the cutting room floor. Who the people were that did all this, we know little of. They called themselves by the general name of church fathers and this is all the average Christian knows of the matter...Disputes, however ran high among the people calling themselves Christians not only to points of doctrine but as to the authenticity of the books.
Constantine, an unbaptised pagan, convened the council of Nicea in the year 325 in order to settle these disputes. A major issue was the nature of the deity they worshipped. Based upon their decisions Jesus was changed from a man to God in the flesh, the Sabbath was changed from Saturday to Sunday, the Passover was changed to Easter. And the N.T. was canonized as a holy book". Unquote.
1 Corinthians 11:14 Doth not even nature itself teach you, that, if a man have long hair, it is a shame unto him?
1 Corinthians 4:33 ... as in all the ekklesia of the saints, your women in the ekklesia let them be silent, for it is not allowed to them to speak; but to be in subjetion, according as also the law says. But if anything they wish to learn, at home ask to their own husbands; for it is a shame for women to speak in the ekklesia.
1 Timothy 2:11 A woman in quietness let learn in all subjection, but a woman to teach I do not allow, nor to exercise authority over man, but to be in quietness; for Adam was formed first, then eve: and Adam was not deceived, but the woman, having been deceived, in transgression has become. But she shall ve saved through the childbearing, if they abide in faith and love and sanctification with discreetness.
