The present volume is a second installment of the commentary on St. Paul's Epistles, of which the author sketched a plan in the preface of his edition of the Galatians. At the same time, it is intended, like its predecessor, to be complete in itself; so that the plan, as a whole, may be interrupted at any time without detriment to the parts. The Epistle to the Philippians presents an easier task to an editor than almost any of St. Paul's Epistles. The readings are for the most part obvious; and only in a few passages does he meet with very serious difficulties of interpretation. Lightfoot took advantage of this circumstance to introduce some investigations bearing on St. Paul's Epistles and on Apostolic Christianity in general.
