Of course he is...but it is not because he had "deeper prayer". And, he is no St. He is just a saint, like you or I...if we are among the elect. His remarks are about being caught up by Christ to view what awaits...like Ezekiel had a vision of Israel. But, to connect this with some kind of "meditative state of prayer" is disingenuous. For the OP to imply that Paul being chosen to be an apostle and is taken to heaven is something you or I or some silly monk somewhere could do (because he had too much time on his hands) and we pray ourselves into a "state", is patently absurd.
I was criticized recently for reading/meditating upon the Psalms as prayer, because they were not my words. Then we get criticized for not reading the Bible.
Really? You place yourself on the same level as St Paul, who had the great privilege of hearing directly from Our Lord and then evangelizing for Him so well on person and in writing that his words have been recognized as divinely inspired? I'm not sure I've ever encountered such monumental egotism. When were your writings incorporated into the New Testament?
The title “Saints” such as St. Paul is because he is home with the Lord.
Better to just be called a “believer” or a “believer in the Lord” in this life.
