This essay is an attempt to show how the language of the Pastoral Epistles can be used as a key to unlock the old secret of their origin. It is not a complete Introduction to these epistles, but only a contribution towards that larger subject. On the other hand, it includes rather more than a series of linguistic studies pure and simple. In the matter before us, language is only one of several factors which are closely interconnected and refuse to be kept in separate water-tight compartments. The full significance of each is only seen in its relation to the rest. --From the preface
