The Apostles' doctrine

Already Jesus, who is described as the "Apostle ... of our confession" in Hebrews 3: 1, said: "My doctrine is not Mine, but His who sent Me" (John 7: 16). As the One sent by His Father, He in turn sent the Apostles and gave them the commission to "[teach] them to observe all things that I have commanded you ..." (Matthew 28: 20).


As Jesus Christ's servants, the Apostles are called and ordained to preach the gospel and to promote obedience of faith (Romans 1: 1, 5). The ministers commissioned by them likewise proclaim Jesus Christ's doctrine to the congregations.


The word of the sermon effected by the Holy Spirit serves to strengthen faith and promote understanding. It imparts comfort, admonishes listeners to act in accordance with the standards of the gospel, and keeps the expectation of Christ's imminent return alive. In this way, believers experience the fulfilment of Jesus' promise: "However, when He, the Spirit of truth, has come, He will guide you into all truth; for He will not speak in His own authority, but whatever He hears He will speak; and He will tell you things to come. He will glorify Me, for He will take of what is Mine and declare it to you" (John 16: 13-14). Thus the sermon inspired by the Holy Spirit also distinguishes itself by glorifying Christ as the Saviour and Redeemer.
