"We do not in anywise presuppose that the books of the New Testament are inspired, but, rather, they are only genuine, authentic documents written by honest men."

From the Catechism of the Catholic Church

"Sacred Scripture is the speech of God as it is put down in writing under the breath of the Holy Spirit."
