Does the Holy Spirit inspire people to write books about Jesus? Yes, but we are only certain of 4 times that this has happened…to Matthew, Mark, Luke and John.
Mr. O’Reilly asserted in this same interview by Ms. O’Donnell that “Father, forgive them for they know not what they do” was not said by Jesus. So Mr. O’Reilly has said that the Lord, the Holy Spirit, is a liar or oops, God makes mistakes.
The Holy Spirit’s work is to testify to the the Word of God and the Word made flesh. The Holy Spirit, the Lord does not testify to falsehoods and so ‘inspires’ them.
Trust the Holy Spirit, not Mr. O’Reilly.
