Skeptic Look on Faith

I wonder how this will be answered by church leaders. This snippet came from an article in Newsweek:

Perhaps the most intriguing possible hint of illegitimacy in the New Testament comes in the Gospel of John, in an exchange between Jesus and the Temple priests. The back-and-forth is sharp, even brutal, with Jesus accusing the priests of failing to live up to the example of their common father, Abraham. Their reply: "We be not born of fornication; we have but one Father, God Himself." In his exploration of this passage, the late Raymond E. Brown, a distinguished scholar and Roman Catholic priest who taught at Union Theological Seminary, wrote: "The Jews may be saying, 'We were not born illegitimate, but you were.' The emphatic use of the Greek pronoun 'We' allows that interpretation."
