The "way" Paul preached

The Campbellite "evangelist" Aaron Erhardt (of Erhardt Publications and Taylorsville Church of Christ) says that since Paul persecuted the "way" in Acts 9:1-2 and later preached the "way" himself, then he must have been preaching the same gospel that Peter preached. 

John Davis of Time for Truth! also uses this "proof" in Time for Truth! News Issue 78 page 13. See the ERRORS of Hyperdispensationalism page

The Campbellite "Church of Christ" says that these three passages prove that Paul preached Acts 2:38 and that he did not receive the new revelation of the Gospel of the Grace of God as stated in Galatians 1:11-12, 2:1-9, Rom. 16:25, Eph. 3:1-9, etc.

Here are the verses that supposedly refute Mid-Acts Dispensationalism.

Acts 9:1-2 And Saul, yet breathing out threatenings and slaughter against the disciples of the Lord, went unto the high priest, And desired of him letters to Damascus to the synagogues, that if he found any of this way, whether they were men or women, he might bring them bound unto Jerusalem.

Acts 19:9 But when divers were hardened, and believed not, but spake evil of that way before the multitude, he departed from them, and separated the disciples, disputing daily in the school of one Tyrannus.

Acts 22:3-4 I am verily a man which am a Jew, born in Tarsus, a city in Cilicia, yet brought up in this city at the feet of Gamaliel, and taught according to the perfect manner of the law of the fathers, and was zealous toward God, as ye all are this day. And I persecuted this way unto the death, binding and delivering into prisons both men and women.

But this proves absolutely nothing, other than the obvious fact that Paul started preaching Jesus Christ after He appeared to Him on the road to Damascus. 

John 14:6 Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.

There is no other "way". 

John 10:1 Verily, verily, I say unto you, He that entereth not by the door into the sheepfold, but climbeth up some other way, the same is a thief and a robber. 

Acts 4:12 Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved.
