Paul's Doctrine

Still, the servant was to continue in the things which he had learned, and been assured of, knowing of whom he had learned them. Never would there come a moment when such were to be abandoned; Paul's doctrine was the last revelation ever given. It was God's secret to those who feared Him and who had an ear to hear. Until we all come in the unity of the faith, it would abide, because the Holy Spirit on earth remained. It has been the last truth restored to the Church of God, as it was the last given. When it was lost at the first, complete ruin supervened. Now when refused, or abused, by taking it up in the form without the power, it sounds as a warning signal to all further progress in those who are thus beguiled of the enemy.
The Scriptures of God are completed by the doctrine of the Church through Paul. "Who now rejoice in my sufferings for you, and fill up that which is behind of the afflictions of Christ in my flesh for His body's sake, which is the church [assembly]: whereof I am made a minister, according to the dispensation of God which is given to me for you, to fulfill the word of God." Col. 1:24, 25.
