Thanks for your informative post, but...
That quote above is actually from Acts chapter 15, the Jerusalem Council. And nothing to do with Paul's confirmation. Perhaps you were referring to Acts chapter nine. However, I see no commissioning by the Apostles there. Ananias laid hands on him for healing and filling with the Holy Spirit. It seems to me that Paul operated independently of the other "super apostles". (2 Corinthians 11:5; 2 Corinthians 12:11) I don't see a solid link of succession. And don't you trace succession through Peter, not Paul? Or, all the Apostles, including Paul?
Acts 9:17-22
Then Ananias went to the house and entered it. Placing his hands on Saul, he said, “Brother Saul, the Lord—Jesus, who appeared to you on the road as you were coming here—has sent me so that you may see again and be filled with the Holy Spirit.” 18 Immediately, something like scales fell from Saul’s eyes, and he could see again. He got up and was baptized, 19 and after taking some food, he regained his strength.
Saul spent several days with the disciples in Damascus. 20 At once he began to preach in the synagogues that Jesus is the Son of God. 21 All those who heard him were astonished and asked, “Isn’t he the man who raised havoc in Jerusalem among those who call on this name? And hasn’t he come here to take them as prisoners to the chief priests?” 22 Yet Saul grew more and more powerful and baffled the Jews living in Damascus by proving that Jesus is the Messiah.
