The arguments used by Josephus Flavius to justify his own betrayal and that of his brethren seem to echo the words of St. Paul, who is considered by universal consent as the one who created the ideological basis for the construction of the Roman church. The two seem to be perfectly in agreement with regard to their attitude toward the Roman world. Paul, for example, considered it his task to free the church of Jesus from the narrowness of Judaism and from the land of Judaea and to make it universal, linking it to Rome. They are also in agreement on other significant points: for example, both of them declare their belief in the doctrines of the Pharisees, which were those that were wholly received by the Roman church [...] There are sufficient historical indications to lead us to consider it possible, if not certain, that the two knew each other and were very close friends.

The correspondence of dates, facts, and people involved is so perfect that it is consequently difficult to avoid the conclusion that Josephus went to Rome to free Paul and his companions and that it was due to his intervention that the apostle was released. This presupposes that the relationship between the two was much closer that that of a simple occasional acquaintance [...] According to the Acts of the Apostles, Paul never lost the opportunity to "preach the kingdom of God and teach those things, which concern the Lord Jesus Christ" to anybody he met. Thus Josephus must have known much more about Christianity than he admits in his works, and his knowledge came directly from the teaching of Paul, of whom, in all likelihood, he was a disciple.
