Yes,...I am following the line of Raymond Brown (a scholar Catholic priest) and Antonio Piñero (a spanish liberal and secular scholar), and some of Bart Ehrman. They agree that there is a little core of true facts in the four Gospels, but much of them are tampered stories. So, to sumarize, Jesus was a religious Jew who met John the Baptist, and did amazing things, as some modern people, but his crucifixion was unexpected even by him. Then, the disciples tried to justify these facts by quoting and reconfiguring passages of the Old Testament. This led to an interesting social phenomenom, because it initialy created a religious comunity with social protection without racial discrimination (Pauline christianity), someting that worked well in the oppressive world of that time.
