What two categories are the Pauline letters divided into?

Answer 1

AnswerScholars divide the letters attributed to Paul into 'Pauline' letters, those thought to have been written by Paul himself, and pseudo-Pauline letters, written in Paul's name by anonymous authors. Fr. Raymond E. Brown, a member of the Vatican's Roman Pontifical Biblical Commission, has expressed his belief that, of the thirteen epistles which say that they were written by Paul, critical scholars have reached a near consensus that only seven are Paul's: 1 Thessalonians, Galatians, 1 & 2 Corinthians, Philippians, Philemon and Romans. Others say that 1 Thessalonians and Philippians are probably also pseudo-Pauline letters.
