Synopsis of the Books of the Bible, by John Nelson Darby, [1857-62], at sacred-texts.com
The Epistle to Titus is occupied with the maintenance of order in the churches of God.
The especial object of those written to Timothy as the maintenance of sound doctrine, although speaking of other things with regard to which the apostle gives directions for the conduct of Timothy. This the apostle himself tells us. In the First Epistle to Timothy we see that Paul had left his beloved son in the faith at Ephesus, in order to watch that no other doctrine was preached there; the assembly is the pillar and support of the truth. In the Second Epistle we find the means by which Christians are to be strengthened in the truth, when the mass have departed from it.
Here, in Titus, the apostle says expressly that he had left him in Crete to set in order things that wee yet wanting, and to establish elders in every city. Although more or less the same dangers presented themselves to the mind of Paul as when writing to Timothy, yet we find that the apostle enters at once upon his subject with a calmness which shews that his mind was not pre-occupied in the same way with those dangers, and that the Spirit could engage him more entirely with the ordinary walk of the assembly; so that this epistle is much more simple in its character. The walk that becomes Christians, with regard to the maintenance of order in their relationships of each other, and the great principles on which this walk is founded, form the subject of the book. The state of the assembly comes but little before us. Truths that flow more entirely from the Christian revelation, and that characterize it, have more place in this epistle than in those addressed to Timothy. On the other hand, prophecies concerning the future condition of Christianity, and the development of the decline that had already commenced, are not repeated here. While stating in a remarkable way certain truths with respect to Christianity, the tone of the epistle is more calm, more ordinary.
