This is a theological commentary on the Greek text; on the foundation of linguistic detail is based a doctrinal exposition. The first section of the Introduction is on the religious ideas of the epistles, and frequent allusion is made throughout the commentary to works on New Testament theology. There are special notes on many of the important theological terms as well as on linguistic points. Attention is also devoted to critical and introductory matters. The commentary is documented with references to works in English, French, and German, for those who wish to follow up the study in greater detail. The aim has been to make the exposition as far as possible self-contained and intelligible to a reader with no other books before him than the New Testament in Greek and the Old Testament in English.
