I do not know if this has been a PB thread before so forgive me if it has. In general the early church held that this was an Epistle of St. Paul. Many still held to this up to the textual criticism movement (both higher and lower.) Since we do not know I take the traditional view that is of Paul (by the Holy Ghost). But I thout it would be intersting to get a feel from the board on this topic. Grace and Peace.
