Maybe you will someday have a neighbor lose a spouse and still invite his or her mother-in-law over for dinner. I doubt very much that s/he will introduce her to you as "my ex-mother-in-law".
What exactly do I not see, perceive, hear, or understand? I quote you scripture and you have no answer for that. All you have is a conjecture that Peter wasn't married while he was an apostle even though Paul specifically describes Peter as having a wife. And your conjecture is not based upon Catholic teaching or history because the Catholic Encyclopedia describes a writing of Clement of Alexandria stating that Peter had children and that his wife was martyred at approximately the same time that he was. Check out the link -- you can even find translations of Clement's Stromata on the internet, but I'll leave that as an exercise for you.Have you noticed that the scriptures I've quoted all agree with one another, and that they also agree with early church documents and tradition? It's no accident.
I think that I'm not the one with the problem seeing, perceiving, hearing, and understanding. Don't feel sorry for me.
