“It is more than possible that Paul was at one time married, and he stated that he had the power (e.g. authority) to lead about a sister, a wife . . . (1 Cor. ch. 9)”
St. Paul had no wife (1 Corinthians 7:7-8).
“Peter had a mother-in-law. Imagine not having the benefit of a wife, but having to put up with a mother-in-law !! And Paul identifies Cephas (Peter) in 1 Cor. ch. 9 as one who led about a sister, a wife.”
There is no evidence that that was Peter’s wife. Also, there was no evidence that Peter’s wife was still alive while Jesus walked the earth.
Peter had a mother-in-law, but that was not HIS wife? WHAT???!
Your ref. to 1 Cor. ch. 7 indicates that Paul was not married. Which is true. I stated that Paul could have previously been married. Then you imply that Peter COULD HAVE BEEN prciously married, by stating that there is no evidence that he was married while Jesus was on earth.
So the same kind of thing could apply to Paul. He could have been a widower.
But then Paul states in the same book, chapter 9, that he had the power (authority) to lead about a sister, a wife, as well as the other apostles, and as the brethren of the Lord, AND AS CEPHAS. Cepahs is Peter.
So it looks like Peter was married, had a mother-in-law, and Peter was leading his wife about with him, as were the other apostles and the brethren of the Lord.
Paul had the power/right ot do the same thing, but elected not to.
