I saw a person whom when asked a question - what gives you the right or authority to speak for Jesus - I saw a steady stream of deflection. Perhaps you saw something different.
Oh, wait, there was something else I almost forgot. The term creed has been bandied about several times by different posters here lately, so I'll add one of mine, a small and short one, and not my words except for my repeating of what the following bold plain emphatic statements from the Meshiah compel me to conclude.
John 5:22
22 for
the Father judges no one, but has committed all judgment unto the Son:
John 8:15
15 You judge after the flesh:
I judge no one.
John 8:50
50 And I seek not mine own glory:
there is One who seeks out and judges.
John 12:47-50
47 And if anyone hears my words,
(rhema), and believes not,
I judge him not: for I came not to judge the world, but to save-deliver the world.
48 The one rejecting me, and receiving not my words,
(rhema), has One that judges him: the Logos that I have spoken, that One shall judge him in the last day.
49
For I have not spoken of myself: but the Father who sent me, He gave me a commandment, what I should say, and what I should speak.
50
And I know that His commandment is life eternal: whatsoever therefore I speak, even as the Father has said unto me, so I speak.
The basic flow of the logic in the above emphatic statements of the Meshiah:
The Father judges no one.
The Father has committed all judgement unto the Son.
The Meshiah himself, (the Christos, or Anointed One), judges no one.
The Logos which the Meshiah has spoken: that One alone is the Judge.
Therefore:
The Father is not the Judge, (John 5:22).
The Son is the only Judge, (John 5:22).
The Meshiah himself says that he is not the Judge, (John 8:15, John 8:50, John 12:47)
The Logos spoken through the Meshiah which the Father gave to him is the only Judge, (John 12:48-50).
The Meshiah or Christos, (Anointed One), is not the eternal Logos Son who is the Word of the Father.
Am I also putting words in the mouth of the Meshiah? No, I simply believe his words and take them to their ultimate conclusions in forming my understanding so as to be true to his doctrine.
