Contradiction with John 7:39
This verse notes that the Holy Ghost was not yet given because Jesus was not yet glorified, which could contradict Acts 1:2 where the disciples receive instruction through the Holy Ghost before Jesus' ascension.
John 7:39: (But this spake he of the Spirit, which they that believe on him should receive: for the Holy Ghost was not yet [given]; because that Jesus was not yet glorified.)
Contradiction with John 16:7
This verse states that the Comforter will not come until Jesus departs, potentially contradicting Acts 1:2, where it implies the Holy Spirit was already involved before Jesus ascended.
John 16:7: Nevertheless I tell you the truth; It is expedient for you that I go away: for if I go not away, the Comforter will not come unto you; but if I depart, I will send him unto you.
Contradiction with Luke 24:49
This verse says the disciples must wait in Jerusalem to be endued with power from on high, which could contradict Acts 1:2 that suggests instructions by the Holy Ghost were given before this empowerment.
Luke 24:49: And, behold, I send the promise of my Father upon you: but tarry ye in the city of Jerusalem, until ye be endued with power from on high.
Contradiction with Matthew 28:10
This verse instructs the disciples to go to Galilee to see Jesus, while Acts 1:2 implies the final instructions were in Jerusalem, creating a setting contradiction.
Matthew 28:10: Then said Jesus unto them, Be not afraid: go tell my brethren that they go into Galilee, and there shall they see me.
Contradiction with Mark 16:7
This verse tells disciples to meet Jesus in Galilee after resurrection, which may contradict the setting and instructions given in Jerusalem per Acts 1:2.
Mark 16:7: But go your way, tell his disciples and Peter that he goeth before you into Galilee: there shall ye see him, as he said unto you.
