Scripture reveals Jesus is the exact representation of God's nature, but Scripture does not tell us that Jesus has God's attributes. The Lord told us the Father is in Him, which is why all the fullness of deity is contained in the Lord, who was a man with a nature like ours.
God's truth is not dependent on how many people accept a doctrine. God has given us His truth in His word, which we need to study in order to understand. Peter warns that we are not to interpret God's word, which is the only way men can come up with Jesus is God.
Men purged the Catholic/Orthodox churches of all Hebrew influence and by doing so purged God's truth from their doctrines. The foundation of Christianity and the true Church of Jesus Christ is the apostles and the prophets, not gentiles who were influenced by pagan Greek traditions and philosophy. Jesus told us that only those who do the will of the Father and endure to the end will be saved, He did not tell us the majority rules. He also told us that we will suffer for His truth. So those who suffered at the hands of the Catholic Church by rejecting its heresies are those who will see and be with the Lord for eternity.
Also the fact you are trying to equate what Arian taught with what I believe only shows your ignorance of Arianism and Biblical truth. Arian believed that Jesus is a minor god, which is pagan mythology. I believe that the Bible tells us that Jesus preexisted as God's plan for the salvation of mankind, not as a divine being. I accept as God's truth what Peter preached in Acts 2. Catholicism rejected the truthfullness of what Peter actually taught by appealing to human philsophy and the traditions of men.
