Oneness of God
Creation-worship is the greatest sin that man can commit because it contradicts the very purpose of his creation. Man was created to worship Allah alone; consequently, the worship of creation, which is the essence of idolatry, is the only unforgivable sin. One who dies in this state of idolatry has sealed his fate in the next life. This is not an opinion, but a revealed fact stated by Allah in his final revelation to man.
Jews ignore the fact that the Oneness of God implies the Oneness of the humankind and distort the idea of the chosen status of the Children of Israel to misappropriate exclusiveness for Divine Grace and to claim racial superiority.
The followers of Jesus split up into two sects immediately after the disappearance of Jesus, and one of them eventually eliminated the other. The sect that prevailed followed St Paul, who ingeniously over-ruled many of the fundamental teachings of Jesus. As a result, we have Christianity which preaches Trinity, Original Sin, and Atonement through the suffering and crucifixion of God’s Only Begotten Son etc.
All of the writers of the Bible believed that God was not Jesus. The idea that Jesus is God did not become part of Christian belief until after the Bible was written, and took many centuries to become part of the faith of Christians.
Matthew, Mark, and Luke, authors of the first three Gospels, believed that Jesus was not God (see Mark 10:18 and Matthew 19:17). They believed that he was the son of God in the sense of a righteous person. Many others too, are similarly called sons of God (see Matthew 23:1-9).
Paul, believed to be the author of some thirteen or fourteen letters in the Bible, also believed that Jesus is not God. For Paul, God first created Jesus, then used Jesus as the agent by which to create the rest of creation (see Colossians 1:15 and 1 Corinthians 8:6). Similar ideas are found in the letter to the Hebrews, and also in the Gospel and Letters of John composed some seventy years after Jesus. In all of these writings, however, Jesus is still a creature of God and is therefore forever subservient to God (see 1 Corinthians 15:28).
Now, because Paul, John, and the author of Hebrews believed that Jesus was God’s first creature, some of what they wrote clearly shows that Jesus was a pre-existent powerful being. This is often misunderstood to mean that he must have been God. But to say that Jesus was God is to go against what these very authors wrote. Although these authors had this later belief that Jesus is greater than all creatures, they also believed that he was still lesser than God. In fact, John quotes Jesus as saying: “...the Father is greater than I.” (John 14:28). And Paul declares that the head of every woman is her husband, the head of every man is Christ, and the head of Christ is God (see 1 Corinthians 11:3).
Therefore, to find something in these writings and claim that these teach that Jesus is God is to misuse and misquote what those authors are saying. What they wrote must be understood in the context of their belief that Jesus is a creature of God as they have already clearly said.
So we see then, that some of the later writers had a higher view of Jesus, but none of the writers of the Bible believed that Jesus is God. The Bible clearly teaches that there is only one true God, the one whom Jesus worshipped (see John 17: 3).
Buddha was a reformer who introduced a number of humanistic principles to the religion of India. He did not claim to be God nor did he suggest to his followers that he be an object of worship. Yet, today most Buddhists who are to be found outside of India have taken him to be God and prostrate to idols made in their perception of his likeness.
