Acts 1 clearly states the simple qualifications for apostleship, which would have permanently excluded Paul. In spite of that, he later became the 13th (or 14th, depending on semantics) apostle based on the Damascus Road story. Countless people throughout the years have claimed to have similar visions and divine appointments, but somehow his was taken seriously. Was that because it was legitimate, or did he just have lucky timing? If it was legitimate, why did he later have so much strife with the original apostles?
Jesus chose 12 Apostles because each Apostle has a throne in heaven to judge the 12 tribes of Israel in the end of days. Only 12 are allowed because there are only 12 thrones of judgement. Judas was removed as an Apostle because he helped to cause the death of Jesus by betrayal all the while professing love for Jesus when he loved money more than the life of Jesus. Jesus gave the remaining 11 Apostles instructions as to how to select the replacement of Judas with very specific requirements. Matthais replaced Judas as the final Apostle.
Saul/Paul the Pharisee (that agreed Jesus should die agreeing with the Hebrew/Jewish High Priest) had killed disciples of Jesus and broke into Christian homes having the occupants thrown in prison. Acts 8:1-3. Later Paul lied saying he did not apprehend them, he just forgets about his victims showing no remorse, regret or repentance. Paul only thinks about himself and his future with no regard for the lives he destroyed or intention of helping the families.
Philippians 3:13
Brethren, I count not myself to have apprehended: but this one thing I do, forgetting those things which are behind, and reaching forth unto those things which are before,"
Paul's prayer is pretense as he wants the homes of widows taken away from them and given to the nearest male relative. If the widow is young with orphans Paul does not want them in his church. Do you believe Jesus would bar a woman from his church for being a young widow with children in need? There could have been young widows that had no family to help her but Paul shows no interest in helping even if the widow has to become a street beggar to survive. NOTE: Jesus was against Paul that took the woman's house away from her. Jesus was for equal rights for women including inheritance rights, as Jesus said,
Matthew 23:14
Woe unto you, scribes and Pharisees, hypocrites! for ye devour widows' houses, and for a pretense make long prayer: therefore ye shall receive the greater damnation."
Remember that even after Paul gave himself the title of Apostle that he still considered himself a Pharisee?
Acts 23:6
But when Paul perceived that the one part were Sadducees, and the other Pharisees, he cried out in the council, Men and brethren, I am a Pharisee, the son of a Pharisee:"
Did Paul tell the Jewish temple that he is a converted Christian and an Apostle? No, Paul said he is a Pharisee.
Jesus said no Pharisee is in the kingdom of heaven.
Matthew 23:13
But woe unto you, scribes and Pharisees, hypocrites! for ye shut up the kingdom of heaven against men: for ye neither go in yourselves, neither suffer ye them that are entering to go in.
Is Paul an Apostle, NO. Paul does say that his lies glorify God. Do you believe Jesus would select a man that boldly says he lies, expecting him to tell people only the truth when Jesus knows he will not?
Romans 3:7
For if the truth of God hath more abounded through my lie unto his glory; why yet am I also judged as a sinner?" However, Paul often said that he does not lie but that is just another of his lies. He does tell other people not to lie that makes him sound righteous but that is part of his pretense plan to sound righteous when he is not.
The true Apostles never called Paul an Apostle because they know he is not one. Peter called Paul, "beloved brother" because Jesus taught him to love your enemies.
Lies never glorify the God that commands not to lie. Paul is a self-professed, unrepentant liar found in the house of Judas after lying and being blind to truth because of it. There are 12 true Apostles and 2 false Apostles in the Bible.
