Paul didn't make up any new doctrine, stop slandering against Paul unless you have solid proof he was a false apostle..
Phillipians 2:5-11
5Your attitude should be the same as that of Christ Jesus:
6Who, being in very nature God,
did not consider equality with God something to be grasped,
7but made himself nothing,
taking the very nature of a servant,
being made in human likeness.
8And being found in appearance as a man,
he humbled himself
and became obedient to death--
even death on a cross!
9Therefore God exalted him to the highest place
and gave him the name that is above every name,
10that at the name of Jesus every knee should bow,
in heaven and on earth and under the earth,
11and every tongue confess that Jesus Christ is Lord,
to the glory of God the Father.
Jesus limited Himself on earth like one of us, although He kept a high degree of Omiscience as He knew exactly what the people around Him were thinking.
