The comments of the epistolary of St. Paul presents the very reading of the Praescriptio and of the other parts of each letter. A reading ofthe first parts (the Praescriptio) not of a single but of all the letters of St. Paul can provide a very complete vision and become a kind of gateway to the writings of the Apostle. The reader will find here not an exegesis of the texts but an approximation that helps to value the data that Saint Paul provides of himself in this first part of his writings, the indications given of his recipients and the main content of his greetings and omens. For the analysis of this first part one will consider a very common grouping of the letters: the first ones in chronological order, the so-called letters of the captivity and the pastoral ones. The limits of this article have omitted any discussion and opinion about the authenticity of some of the letters: you only want to present what these brief texts say.
