Clement of Rome (c 35-100)

The Roman Catholic Church considers Clement of Rome to be the fourth Pope. He is called Clement of Rome to distinguish him from Clement of Alexandria. The Catholic Encyclopedia tells us he is the "first of the successors of St. Peter of whom anything definite is known, and he is the first of the 'Apostolic Fathers'". Of the two so called Clementine epistles, I Clement is a letter to the Church of Corinth, and considered genuine. The book commonly called II Clement is more likely a sermon and many question whether it is from the pen of Clement of Rome. These are the earliest of Christian writings that are not in the Bible.

On Scripture Clement wrote: "You have searched the scriptures, which are true, which were given by the Holy Spirit; you know that nothing unrighteous or counterfeit is written in them (I Clement 45.2-3)." Showing the high regard he had for scripture.
