Most Christians does not believe that Christ is not God. They thought that the belief of the early christians about Christ is that he is a God incarnated: a God and a human.
But if we will just examine the bible and history, we will understand that what Iglesia ni cristo teaches about Christ is the true and original belief of the early Christians.
Let us read some books regarding this:
George Eldon Ladd, a protestant bible scholar says:
“… The early Christian concept of jesus was that of man who was mightily endowed by the spirit of god.” The young Church
Ronald J. Wilkins, a catholic priest says:
“… The apostles and the early Christians did not experience jesus as god in human disguise or as god pretending to be human (this is one reason that the early church rejected fanciful and wildly imaginative accounts of jesus’ life). They experienced him as a human. He was so real in his life, so genuinely human in his spirit, and so convincing in his words that they believed in him. They felt that whatever human life really was, Jesus as a person expressed that life.” The emerging church, part one
Bernard Lohse, a historian says:
“… As one church historian, Bernard Lohse, writes Motive in Glauben (Motivation of belief): ‘Arius reminds us that jesus, as he described in the gospels, was not a god who walked this earth, but truly a human being. Of course, by his very humanity, jesus proved his full community with God. ’” The Jesus establishment
Others...
“We read gospels and the book of acts in the light of our understanding of the pre-existence and the incarnation of god the son. However, the early Christians had no such concepts in their minds. They had no doctrine of the deity of Christ…” The young church: Acts of the apostles
“Jesus was not called God in those early days…” New testament Commentary
“The crisis grows out of a fact now freely admitted by both Protestant and Catholic theologians and exegetes: that as far as can be discerned from the available historical data, jesus of Nazareth did not think he was devine…” The first coming: How the kingdom of God became Christianity
“Jesus never claims to be god, personally…” Honest to god
“It was when Christianity spread out into pagan world that the idea of jesus as a savior God emerged.” The meaning of the dead Sea scrolls
“The earliest post-New testament writers, known as the Apostolic fathers, continued the development that had emerged in the later new testament period of calling Jesus God. Ignatius of Antioch, writing in the second century to the Ephesians, declares, ‘Jesus Christ our God was conceived of Mary’ (Eph 18:2) and ‘God was now appearing in human form’ (Eph 19:3)” Word Become Flesh
“The council could not agree and after two years, impatient at the delay, the emperor Constantine appeared and addressed the assembly, ordering them to agree on the divinity of Christ…” Challenge of a liberal Faith
“When constantine picked out and convened the 318 bishops for the council,the background was pure power politics, religious concerns taking very much of a backseat. Even the Charismatic bishops can have been in no doubt about that, for not only did the emperor preside over the council, he also expressly proclaimed that his will was ecclesiastical law. The senior pastors accepted him as ‘universal bishop’, even though he was uncrowned, and let him take part in votes on church dogma as a secular prince.” Miracles of the Gods
“Once this “Nicene Creed” had been publicly signed by all the bishops and promulgated by Constantine, it became the official creed for all Christians. To deny the divinity of outside of the Christian community and was a crime against the state.” The emerging Church: Part one
Let us now consult the BIBLE concerning Jesus and God, the Father:
Apostle Paul says:
“There is one God and one mediator so that human beings can reach God. That way is through Christ Jesus, who is himself human.” I tim. 2:5
“People of Israel, listen to these words: Jesus from Nazareth was a very special man. God clearly showed this to you by the miracles, wonders, and signs he did through Jesus. You all know this, because it happened right here among you.23 Jesus was given to you, and with the help of those who don't know the law, you put him to death by nailing him to a cross. But this was God's plan which he had made long ago; he knew all this would happen.” Acts 2:22-23
“This is how the birth of Jesus Christ came about. His mother Mary was engaged to marry Joseph, but before they married, she learned she was pregnant by the power of the Holy Spirit.” Matt. 1:18
“I am a man who has told you the truth which I heard from God, but you are trying to kill me. Abraham did nothing like that.” John 8:40
Now its clear, the bible teaches us that Jesus is a MAN and not God, he is a man but not an ordinary man, but doesnt mean he is God. If we read the bible from cover to cover, Jesus NEVER CLAIMED that he is God, the God in the OLD TESTAMENT and the GOD in NEW TESTAMENT did not change, its the same, the God of the Jews, Abraham, the Apostles, Jesus Christ and the early Christians, it is no doubt, it is the ONLY ONE TRUE GOD, THE FATHER.
