"He that rejecteth me, and receiveth not my Words, hath one that judgeth him, THE WORD THAT I HAVE SPOKEN, THE SAME SHALL JUDGE HIM IN THE LAST DAY.
For I have not spoken of myself; but the Father which sent me, HE GAVE ME A COMMANDMENT, WHAT I SHOULD SAY AND WHAT I SHOULD SPEAK.
And I know that His commandment is life everlasting: WHATSOEVER I SPEAK, THEREFORE, EVEN AS THE FATHER SAID UNTO ME, SO I SPEAK." John 12:48-50.
When Peter trusted in his own understanding, He attempted to counsel Jesus, that, He didn't need to die upon the cross. Jesus looked at him and said, "Get thee behind me, Satan...!" Mt 16:21-26.
When James and John wanted to follow the example of Elijah (denominational precedent?) and call fire down from heaven upon the Samaritans, Jesus said to them, "Ye know not what manner of spirit ye are of!" Lu 9:54,55.
When Judas followed his heart, Satan filled it and he betrayed the Lord. Lu 22:3.
These four disciples were with Jesus, 24/7, yet, when they trusted in their own opinions, became tools of Satan, who was attempting to thwart God's plan of salvation.
So, with all due respect, who do we think we are with our various denominational traditions and opinions?
Every doctrine should be studied Genesis-Revelation, before it is taught, but, this is not done, because we lack reverence for God's holy Word.
Jesus spoke, only, the Words, that, the Father gave Him to speak. "He that saith he abideth in Him, ought himself so to walk, even as He walked." 1 John 2:6.
We will, each one of us, stand before our Lord Jesus Christ and give an account for how we lived and presented His "God Breathed" Word to mankind. 2 Tim 3:16.
There is, only, one authority - His "God Breathed" Word.
