In 2 Thess. 2:2 Paul warns against letters that claim to come from him but do not. Thus in 11 places in his letters Paul either identifies himself or gives his signature. These features support the conclusion that all the NT letters attributed to Paul are in fact authentic (rather than having been written by someone else “pseudonymously” in Paul’s name).
