I know that whether or not Peter was or was not married at the time of the Bible event is of little matter in the "big picture". Thats one of the beauties of the Catholic Church,despite what appears to an outsider as a rigidity and demand for conformity it leaves a lot of room for enlightening discussions about a plethora of things. It also clearly states those things that are foundational and must be believed because they are "what is",so to speak.
Sarah, yes, is my daughter. She just came to visit me at work. Unfortunately, she had fallen asleep on the way over and didn't want to show her beautiful eyes to anyone. Sarah is Hebrew for "princess" and I couldn't think of a more fitting name.
