The apostles were not politicians with "agendas". But it appears that you have your own. As St Paul stated: So then, brothers and sisters, stand firm and hold fast to the teachings we passed on to you, whether by word of mouth or by letter.
As to what you have stated a preponderance of Christian biblical scholars believe other wise. In the end we will not be judged by our scholarship although the faithful scholars will be like the stars in magnificence such as Saint Thomas Aquinas, rather we will be judged by our love and if we guided people on the path of  and to God. 

From what you have said it is almost like disfavor and disregard when you talk of a collection of documents so blithely: It is the Word of God.
