<P> Some scholars today maintain the traditional claim that Luke the Evangelist, an associate of St. Paul who was probably not an eyewitness to Jesus' ministry, wrote the Gospel of Luke and Acts of the Apostles . Scholars are also divided on the traditional claim that Mark the Evangelist, an associate of St. Peter who may have been an eyewitness to Jesus' ministry, wrote the Gospel of Mark . Scholars are more divided over the traditional claim that Matthew the Apostle wrote the Gospel of Matthew and that John the Apostle wrote the Gospel of John . Opinion, however, is widely divided on this issue and there is no widespread consensus . </P> <P> The Gospel of Luke and the Acts of the Apostles were both written by the same author, and are thus referred to as the Lucan texts . The most direct evidence comes from the prefaces of each book; both were addressed to Theophilus, and the preface to the Acts of the Apostles references "my former book" about the ministry of Jesus . Furthermore, there are linguistic and theological similarities between the two works, suggesting that they have a common author . </P> <P> The Pauline epistles are the thirteen books in the New Testament traditionally attributed to Paul of Tarsus . The anonymous Epistle to the Hebrews is, despite unlikely Pauline authorship, often functionally grouped with these thirteen to form a corpus of fourteen "Pauline" epistles . </P> <P> Seven letters are generally classified as "undisputed", expressing contemporary scholarly near consensus that they are the work of Paul: Romans, 1 Corinthians, 2 Corinthians, Galatians, Philippians, 1 Thessalonians and Philemon . Six additional letters bearing Paul's name do not currently enjoy the same academic consensus: Ephesians, Colossians, 2 Thessalonians, 1 Timothy, 2 Timothy and Titus . </P>
