The Trinity is late-fourth century, having been passed into law during the Nicene Council in C.E. 381. But the idea predates this and even predates Christianity, though in various forms. In other words, the Christians didn't invent it, they glommed it. And some say they butchered it, as well.
The concept of a Trinitarian godhead harkens from Egypt, and is also part of the Hindu godhead. Both cultures had heavily influenced Roman thought by the time the Trinitarian disputes came about, but by then, Egypt was an important center of Christian power. To try to develop a Trinitarian concept of deity from Hebrew Scripture is a stretch, at best, and even to develop it from Christian scripture is sketchy. When Erasmus published his New Testament, people objected that it did not have any passages which teach the Trinity, so he introduced, on very flimsy evidence, I John 5:7:
For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one.
Only the King James versions retain this passage without comment: the rest relegate it to footnotes.Another passage that is used to bolster the Scriptural basis for the doctrine of the Trinity is Matthew 28:20:
Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost
This really says nothing about a Trinity, but merely mentions three names. Like the other New Testament writers, Matthew was not very precise in this or any other concept. This precision came later. Other baptismal formulae instruct Christians to baptize in the name of Jesus, and some sects use this parallel to teach that Jesus is the Father and the Holy Ghost, that there is no Trinity.
Before the Nicene Councils consolidated The Dogma Of The One True Faith, Christian ideas along these lines were extremely varied. Many Christian sects, most notably the Christadelphians,Christian Science, Jehovahs Witnesses, Mormonism - (The Community of Christ, The Church of Jesus Christ of Latter-day Saints, Arian Catholicism, Unitarianism, Oneness Pentecostals, United Church of God -reject the Trinity. In fact, their materials are as good as any when trying to balance the pro-Trinity arguments of the so-called orthodox Christians. But contrary to what they say (and the Trinitarians, as well), there was no real consensus and nothing resembling precision on this or any other matter during the first few centuries of the Church.


P.S.
Every man should be mentally honest. He should preserve as his most precious jewel the perfect
veracity of his soul. He should examine all questions presented to his mind, without prejudice-unbiased, preconceived opinions, hatred, contempt, disdain, are the enemies of truth and progress. His object and his only object should be to find the truth. He should weigh the evidence, the arguments, in honest scales-scales that passion or interest cannot change. If it be good for man to find the truth -- good for him to be intellectually honest and hospitable,
then it is good for others to know the truths thus found. Truth is the mother of joy. Truth civilizes, ennobles, and purifies. The grandest ambition that can enter the soul is to know the truth.

Nothing but falsehood needs the assistance. The wise, the really honest and intelligent, are not swayed or governed by numbers - by majorities.

No, I believe the atheists butchered it. Go back to your atheist websites and keep your bvllsh.it there:

One holy for each person.

The historic roots of the Trinity should be enough to convince a person that the doctrine is extra-biblical. Scholars admit that it was a developed doctrine which took centuries to formulate. And it was not until the 8th century that it was fully completed.

It was in ancient time that the first man to coin the word "Trinity" came along, named Tertullian (150 - 225 AD) and the first who said that God was Three persons in one substance about the year 200. Never before Tertullian had anyone heard of the word "Trinity". This man was originally "Binitarian" - having believed in two persons. He believed that the Holy Ghost was more of a "thing" and not God, Himself. But the "Montanists" taught him to believe in the Parakeet as being more personal than what he formerly felt. Thus the Holy Spirit became the third eternal person in his later thinking

After Tertullian, came Origen (185 AD - 254 AD). This man derived much of his thoughts from pagan philosophy of the Greeks. He believed that souls pre-existed conception and that even Satan would eventually be saved. He believed Jesus was born of the Father before all other creatures, and that "the Holy Spirit was associated in honour and dignity with the Father and the Son. But in His case it is not clearly distinguished whether He is to be regarded as born or innate, or also as a Son of God or not," according to his book, On the Principles. Origen was the first who clearly taught that there were three persons who were eternal. He taught that the Son eternally was being generated from the Father. (1:2:2; 1:2:4).

Towards the end of this Age, more and more writers began expressing their beliefs about God in Trinitarian terms. Yet they still saw the Son and the Spirit as inferior to the Father. Only two men seemed to write in what is agreeable to the modern Trinitarian doctrine. These men were Gregory Thaumaturgus and Dionysius of Rome.

Most of the Fourth Century passed before the orthodox Trinitarian doctrine was created. Please note that Trinitarianism was originated by people who did not believe in the absolute deity of Jesus Christ. Modern day Trinitarians do not even agree with what the originators of the Trinity believed!

By the end of the fourth century there was a great controversy between those who believed that Jesus was another being separate from God and inferior to God, and those who believed that Jesus was a coeternal person beside the Father making up one God. Athanasius led the group who believed in three persons while Arius led the other group.

n 325 AD, Athanasius' view won the day at the Nicean council. But the idea of a Trinity was not completely declared until the Council at Constantinople in 381 where they declared God to be three eternal persons. At this latter council they declared the Holy Spirit was a third eternal person. The Athanasian Creed is the declaration held by Roman Catholics and most Protestants today. It was created in the fifth century. Modern orthodox Trinitarians stands on this creed.

In order to accept the doctrine of the Trinity one must believe what the Roman Catholic Church teaches in their doctrine of Tradition and Magisterium. This doctrine declares that the Apostles did not have all the truths of God and that the "Church" formulated doctrines AFTER the Bible was written which are to be reckoned to be as important as the truths explicitly taught in the Bible. Since Trinity was not taught in the Bible, but formulated in the fourth century, it nevertheless must be believed since the "Church" said it was true.

I still couldn't get an answer to my question. If he was God the Son, then how on earth Jews - whom Christians used to hate so much - could kill the Jesus Christ?
