Despite interventions and manipulations of the Scriptures we know that the old testament contains many things that would never appear in the new: sacrifices of animals, wars, murders etc. says that it now has new validity, by what the Church often said that God simply has changed my mind, but already in the Old Testament God said: I, God, do not change, a resounding phrase that leaves no room for doubts, or also: Christ is always the same. Therefore, the fact that there are an old and a new testament, you can not be explained by simply saying that God has changed. The Church says so, but in the same Bible is not on any side. And Jesus said so clearly and he was the reason why the New Testament was written. Simply the Bible contains many errors.
Dios has in no way changed, is the man who has introduced errors in the Bible. Between 380 and 400 emerged a priestly caste with the idea that the original Christians or own teaching of Jesus de Nazareth were not at all valid or valuable. Thus the Church of Rome wanted to assume the leading role, for what I needed scriptures that could endorse and legitimize his plan. Therefore he commissioned doctors, lawyers and theologians select from the Scriptures that were circulating, which could correspond to your purposes. In the 4th century Roman Catholicism was the official religion of the Roman Empire and contradict the Church was paid with the death penalty.
Therefore imagine that the selection of texts not an open-minded independent investigator did it. Damasus I commissioned this task to St. Jerome, a lawyer who had to select according to the interests of the Church while using your criteria, that it was not always easy. Jerome was fully aware that future generations would call him forger, because for example spoke of the existence of a secret text of the Gospel of Matthew, which never saw the light. It is no coincidence that the great library of Alexandria burns in the year 389 and that the Church itself would disappear other many writings, so that what today day seems to us a compact text, actually had a process of drafting was not always impartial and with an arbitrary selection criteria, which obviously led to a humanity bearing unexpected and catastrophic consequences even to this day. Despite all no one can say that the current Bible contains nothing of what Jesus de Nazareth wanted in principle. For example, in it we find the Sermon of the mountain and in the old testament the ten commandments. It has also saved what they told great prophets like Isaiah that left his vision of the Kingdom of peace, which is becoming increasingly more sense at this time of great transformations written. Don’t you have time to give a new direction to humanity, leaving behind all these fakes and human interests and doing what we really wanted to send Jesus, the Christ? The wonderful principles of the Sermon on the mount marked a new direction for a new time, you each can contribute.
