The Acts of the Apostles. — See Introduction as to the title thus given to the Book.
(1) The former treatise. — Literally, word, or discourse; but the English of the text is, perhaps, a happier equivalent than either. The Greek term had been used by Xenophon (Anab. ii. 1; Cyrop. viii. 1, 2) as St. Luke uses it, of what we should call the several “Books” or portions of his Histories. The adjective is strictly “first” rather than “former,” and the tense of the verb, “I made,” rather than “I have made.”
O Theophilus. — See Note on Luke 1:3. It has been thought that the absence of the words “most excellent” implies that the writer’s friendship with Theophilus was now of a more intimate and familiar nature. It is possible, just as a like change of relation has been traced in Shakespeare’s dedication of his two poems to the Earl of Southampton, but the inference is, in each case, somewhat precarious.
That Jesus began both to do and teach. — The verb “begin” is specially characteristic of St. Luke’s Gospel, in which it occurs not less than thirty-one times. Its occurrence at the beginning of the Acts is, accordingly, as far as it goes, an indication of identity of authorship. He sought his materials from those who had been “from the beginning” eye-witnesses and ministers of the word (Luke 1:2).
