Doctrine of CHRIST (Hebrews 6:1-7) or church doctrines?

Too much time is wasted debating, dissenting and disputing the word of God instead of building the house of God, “Who hath saved us, and called us with a holy calling, not according to our works, but according to his own purpose and grace, which was given us in Christ Jesus before the world began” (2 Timothy 1:9).

Notwithstanding the proliferation of religions and church denominations, there is only one building of the Kingdom of God through the Holy Spirit, built upon the foundation of the apostles and prophets, Jesus Christ himself being the chief cornerstone; in whom all the building fitly framed together to grow to the end of time unto a holy temple in the Lord (Ephesians 2:20–22).

At the end of time, it is not a specific religion or church denomination as it is the doctrines of many that will be redeemed from this earth. We are to beware of adhering to the doctrines of men; we should obtain knowledge of and obey the word of God. Jesus warned of this very fact when he sent his angel with letters to the early seven churches in the Book of Revelation by John (Revelation 1:11). 

“[EVERY GOOD GIFT AND EVERY PERFECT GIFT IS FROM ABOVE], and cometh down from the [FATHER OF LIGHTS], with whom is no variableness, neither shadow of turning” (James 1:17).

“[FOR MANY DECEIVERS] are entered into the world, [WHO CONFESS NOT THAT JESUS CHRIST IS COME IN THE FLESH]. This is a deceiver and an antichrist.

Whosoever transgresseth, and abideth not in the [DOCTRINE OF CHRIST], hath not God. [HE THAT ABIDETH IN THE DOCTRINE OF CHRIST, HE HATH BOTH THE FATHER AND THE SON]. If there come any unto you, and bring not this doctrine, receive him not into your house, neither bid him God speed: For he that biddeth him God speed is partaker of his evil deeds” (2 John 1:7, 9-11).

When King Jesus was here on this earth he was asked about his doctrine.

“Jesus answered them, and said, ‘[MY DOCTRINE IS NOT MINE, BUT HIS THAT SENT ME]. If any man will do his will, he shall know of the doctrine, whether it be of God, or whether I speak of myself. He that speaketh of himself seeketh his own glory: but he that seeketh his glory that sent him, the same is true, and no unrighteousness is in him’” (John 7:16-18).

“[ONE LORD, ONE FAITH, ONE BAPTISM, ONE GOD AND FATHER OF ALL], who is above all, and through all, and in you all. But unto every one of us is given grace according to the measure of the [GIFT OF CHRIST]” (Ephesians 4:5-7).
