"The two threads which run through this Epistle-the defence of the Apostle's own authority, and the maintenance of the doctrine of grace-are knotted together in the opening salutation. By expanding his official title into a statement of his direct commission from God, he meets the personal attack of his enemies; and by dwelling on the work of redemption in connection with the name of Christ (v. 4) he resists their doctrinal errors."-Lightfoot.-G.
