Many historic books and writers argue and discuss this very critical case, it is not only the Bible that denies this, there are writers as well. Western writers argue this and disagree if Jesus is a human, a God or both. Surely there is doubts surrounding this topic otherwise we wouldn't have seen all of these arguments and even books. When writing about Christian history there must be an introduction about how the Christianity formed and struggles between the groups and believes.
In "
Lost Christianities: The Battles for Scripture and the Faiths We Never Knew"
The author wrote about how the today Christianity was formed, and "offers a fascinating look at these early forms of Christianity and shows how they came to be suppressed, reformed, or forgotten...Modern archaeological work has recovered a number of key texts, and as Ehrman shows, these spectacular discoveries reveal religious diversity that says much about the ways in which history gets written by the winners. Ehrman's discussion ranges from considerations of various "lost scriptures"--including forged gospels supposedly written by Simon Peter, Jesus's closest disciple, and Judas Thomas, Jesus's alleged twin brother--to the disparate beliefs of such groups as the Jewish-Christian Ebionites, the anti-Jewish Marcionites, and various "Gnostic" sects.....The proto-orthodox Christians won out over many other groups, and bequeathed to us the four Gospels, a church hierarchy, a set of practices and beliefs, and doctrines such as the Trinity. Ehrman eloquently characterizes some of the movements and Scriptures that were lost, such as the Ebionites and the Secret Gospel of Mark, as he outlines the many strands of Christianity that competed for attention in the second and third centuries. He issues an important reminder that there was no such thing as a monolithic Christian orthodoxy before the fourth century."

And the book
"When Jesus Became God: The Struggle to Define Christianity during the Last Days of Rome"
it is enough what is written about the book " Ruled by a Christian emperor, followers of Jesus no longer feared for the survival of their monotheistic faith, but they found themselves in different camps—led by two charismatic men—on the topic of Christian theology. Arius, an Alexandrian priest and poet, preached that Jesus, though holy, is less than God, while Athanasius, a brilliant and violent bishop, saw any diminution of Jesus' godhead as the work of the devil. Between them stood Alexander, the powerful Bishop of Alexandria, in search of a solution that would keep the empire united and the Christian faith alive."
Those books and more are written by western writers.

It is very normal to have authors answer these books, because the divinity of Jesus is already debatable and controversial.
It is strange to have conference and meetings to discuss what to worship and how to worship. Stranger than this, the struggle between the nature of Jesus (God or human) and make agreement on one. This is only in Christianity history.
