And I also noticed that Paul brought him and others up to speed with just a couple of sentences.
(Acts 19:1-6) 19 In the course of events, while A·pol′los was in Corinth, Paul went through the inland parts and came down to Eph′e·sus, and found some disciples; 2 and he said to them: "Did you receive holy spirit when YOU became believers?" They said to him: "Why, we have never heard whether there is a holy spirit." 3 And he said: "In what, then, were YOU baptized?" They said: "In John's baptism." 4 Paul said: "John baptized with the baptism [in symbol] of repentance, telling the people to believe in the one coming after him, that is, in Jesus." 5 On hearing this, they got baptized in the name of the Lord Jesus. 6 And when Paul laid his hands upon them, the holy spirit came upon them, and they began speaking with tongues and prophesying.
Paul didn't need to have an annual meeting to reveal this lol.
