Christ said to the apostles that He had much more to tell, but they couldn't bear it. He then promised the Holy Spirit would come to teach them, as a continuation of His ministry. That's why we respect the words of the apostles as inspired by Jesus Himself. Jesus gave them the authority.
In the same reasoning, Paul met Jesus, when He was ressurected and was instructed by Him for 3 years in Arabia. The apostles themselves doubted that at first, but when they knew about the mighty miracles and the powerful testimony that Paul was giving, they accepted him and his authority as apostolic.
John also received the book of Revelations from Jesus Himself, as is stated in the text.
