Did it? He was called by Christ Himself.
26When he came to Jerusalem, he was trying to associate with the disciples; but they were all afraid of him, not believing that he was a disciple. 27But Barnabas took hold of him and brought him to the apostles and described to them how he had seen the Lord on the road, and that He had talked to him, and how at Damascus he had spoken out boldly in the name of Jesus. Acts 9:26-27 NASB
Do you claim that anyone after Paul was chosen by God and speaks with the authority of an apostle?
Let's be clear of what an apostle is first. If we hold it to be the traditional definition then there are no apostles after the original disciples and Paul died as none had an eyewitness account of the resurrected Christ.
Nor does the example of Paul take away from the fact that there were those who were chosen and commissioned by the apostles. Paul himself did this with Timothy and Titus, and instructed Titus to do the same. How can you claim that this line of commissioning shown in the Bible has come to an end?
No one is denying the disciples and Paul had converts and some went into the ministry.
The roman catholic position is contrary to this in that it claims that ONLY those commissioned by the disciples and so on and so on are "legit". By rcc teaching Paul would not be legit as he did not receive his commission from the original disciples.
Yet Paul's example shows otherwise.
What the catholic cannot deny, or shouldn't deny, is the ability of Christ to call into commission today men into the ministry as He determines and how He determines.
Paul is that example.
And how do you know who these are? How can you know that I might not be one?
