I have not wished to cumber my pages with constant quotations. But in former years I have read, in some cases with much care, the following commentators--St. Augustine's _Tractatus_, St. John Chrysostom's Homilies on the Gospel (full of hints upon the Epistles), Cornelius à Lapide; of older post-Reformation commentators, the excellent Henry Hammond, the eloquent Dean Hardy, the precious fragments in Pole's _Synopsis_--above all, the inimitable Bengel; of moderns, Düsterdieck, Huther, Ebrard, Neander; more recently, Professor Westcott, whose subtle and exquisite scholarship deserves the gratitude of every student of St. John. Of Haupt I know nothing, with the exception of an analysis of the Epistle, which is stamped with the highest praise of so refined and competent a judge as Archdeacon Farrar. But having read this list fairly in past years, I am now content to have before me nothing but a Greek Testament, the Grammars of Winer and Donaldson, the New Testament lexicons of Bretschneider, Grimm, and Mintert, with Tromm's "Concordantia LXX." For, on the whole, I really prefer St. John to his commentators. And I hope I am not ungrateful for help which I have received from them, when I say that I now seem to myself to understand him better without the dissonance of their many voices. "Johannem nisi ex Johanne ipso non intellexeris." III. It only remains to commend this book, such as it is, not only to theological students, but to general readers, who I hope will not be alarmed by a few Greek words here and there. I began my fuller study of St. John's Epistle in the noonday of life; I am closing it with the sunset in my eyes. I pray God to sanctify this poor attempt to the edification of souls, and the good of the Church. And I ask all who may find it useful, to offer their intercessions for a blessing upon the book, and upon its author. WILLIAM DERRY AND RAPHOE. THE PALACE, LONDONDERRY, _February 6th, 1889_. MERCIFUL GOD, we beseech Thee to cast Thy bright beams of light upon Thy Church, that it being enlightened by the doctrine of Thy blessed Apostle and Evangelist St. John, may so walk in the light of Thy truth, that it may at length attain to the light of everlasting life, through Jesus Christ our Lord. Amen. FOOTNOTE:
