I consider the Bible to be an important religious text, worthy of study. The fact that it is consistent on this point means merely that at a certain point in time various people agreed about something. Others may have believed something different, but of course their ideas do not appear in this text.

Buddhism and Hinduism are also reasonably consistent, but have different schools within them. If in modern times we collected the works of Richard Dawkins, Sam Harris, Daniel Dennett, and Christopher Hitchens, and published them together as one supposedly authoritative text, that wouldn't make the contents any more true.

I don't think that I have to provide evidence that the Holy Spirit is a person. On the contrary, as I suggested in my previous response, the onus is on Christians to provide evidence, based on modern experience, that the Holy Spirit is a person, not merely quote passages from the Bible.

Regarding Josephus and those quotes, you will of course believe what you want to believe. However: “For hundreds of years these passages in Josephus were seized on by Christian historians as conclusive proof that Jesus existed. That is, until scholars began to examine the text a little more critically. No serious scholar now believes that these passages were actually written by Josephus. They have been clearly identified as much later additions. They are not of the same writing style as Josephus and if they are removed from the text, Josephus' original argument runs on in proper sequence. Writing at the beginning of the third century, Origen, whom modern authorities regard as one of the most conscientious scholars of the ancient Church, tells us that Josephus did not believe that Jesus was the Christ, since he did not believe in any Jewish Messiah figure”. (The Jesus Mysteries, Timothy Freke and Peter Gandy, p167).

[ref: The Messiah Jesus and John the Baptist, by Robert Eisler. “As a matter of fact, not a single Greek, Latin, or Slavonic or other Josephus text has come down to us which has not passed through the hands of Christian scribes and Christian owners”.

In other words, the passages you refer to are obvious frauds introduced by later Christians in order to promote their message. I can't believe that you are using them, unless you want to join the ranks of those desperate apologists.
