We Catholics do not base our faith solely on the bible. Just as equally important we also base our faith on oral tradition. Here are some references that clearly state Jesus is God.
St. Ignatius of Antioch, Letter to the Romans Address (c. 110 AD)
“Ignatius, also called Theophorus, to the Church that has found mercy in
the greatness of the Most High Father and in Jesus Christ, His only Son: to
the Church beloved and enlightened after the love of Jesus Christ, our God,
by the will of Him that has willed everything which is: to the Church also
which holds the presidency in the place of the country of the Romans ... To
those who are united in flesh and in spirit by every commandment of His,
who are filled with the grace of God without wavering, and who are filtered
clear of every foreign stain, I wish an unalloyed joy in Jesus Christ, our
St. Melito of Sardes, Fragment in Anastasius of Sinai 13 (c. 177 AD)
“The activities of Christ after His Baptism, and especially His miracles,
gave indication and assurance to the world of the Deity hidden in His flesh.
Being God and likewise perfect man, He gave positive indications of His
two natures: of His Deity, by the miracles during the three years following
after His Baptism; of His humanity, in the thirty years which came before
His Baptism, during which, by reason of His condition according to the
flesh, he concealed the signs of His Deity, although He was the true God
existing before the ages.”
These and others like it are just as important as the bible as faithful witnesses to divine revelation. It is very similar to the hadiths and their importance in helping to understand the Quran.
I know this is difficult for you to accept, I just wanted to help you understand the Catholic faith. The reason why we do not accept your interpretation is because your approach is fallible, meaning you can make mistakes just like anyone else including myself in interpreting scripture. Only the bishops in communion with the pope can make authentic interpretations in dealing with doctrines without error because they descend from a line of authority, the “apostolic succession” which is a divine institution, instituted by Christ Himself.
