For example, Norman Perrin analyzed the Greek used by the author or authors of the Pastoral Epistles, finding that over 1/3 of their vocabulary is not used anywhere else in the Pauline epistles; more than 1/5 is not used anywhere else in the New Testament, while 2/3 of the non-Pauline vocabulary are used by 2nd century Christian writers. Richard Heard, in 1950, had this to say: “The evidence of teaching as of style and vocabulary is strongly against Paul’s authorship, nor are these arguments seriously weakened by any supposition that the epistles were written late in Paul’s lifetime and to meet a new type of situation. The three epistles show such a unity of thought and expression that they must be the work of one man, but for the author we must look rather to one of Paul’s admirers than to Paul himself.”
