Wasn’t the Apostle Peter married? If not, how did Jesus heal his mother-in-law?
The article tries to make the hairsplitting point that "maybe Peter had a mother-in-law because he was married at one time, but his wife died" as a way of getting around the obvious fact that Peter was, in fact, married. This fails on two points:
1) Paul quite clearly states that Peter and other apostles were "leading about wives" (i.e. were married) in I Corinthians 9:5, and indeed, he makes the point that he, himself, was perfectly within his rights to do the same.
2) In that culture, when a woman's husband died, she returned to her own kinship group. If Peter's wife had died before his calling from Jesus, his former mother-in-law would have returned to her own ancestral family to be cared for by them, not Peter.
