The Doctrine Of Christ & (The Doctrine Of God)
When we speak of “doctrine” we are speaking about a specific set of teachings or instructions.
Usually, it is viewed as:
The Doctrine of Christ was, and is, the Doctrine of God that was given to Christ (John 7:16, 8:28, 2Jn 1:9) to implement.
(John 8:28) Then said Jesus unto them, When ye have lifted up the Son of man, then shall ye know that I am he, and that I do nothing of myself; but as my Father hath taught me, I speak these things.
(2Ti 3:16) All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:
(2Tim 4:3) For the time will come when they will not endure sound doctrine; but after their own lusts shall they heap to themselves teachers, having itching ears;
(Tit 1:9) Holding fast the faithful word as he hath been taught, that he may be able by sound doctrine both to exhort and to convince the gainsayers.
(Tit 2:1) But speak thou the things which become sound doctrine:
Jesus warned that we must have the courage to openly confess Him. If we do not have this courage, Jesus will not confess our name as brethren (Mat 10:32-33). People in the New Testament times confessed Jesus’ name (Acts 4:10-12; 8:37). Our confession, of who Jesus is, is to be with our mouth, an oral confession (Rom 10:10).
Any denomination that follows a doctrine other than that established by Christ cannot be the Lord’s church.
