FYI, I know of several saints who also had this arrangement with their spouses. They agreed to live celibately.
Our modern world is so hung up on sexuality that we automatically think that way.
Please try thinking out of the box — as God was thinking in providing a guardian for Mary and Jesus.
Ohhh... is that what God was thinking? Now I understand everything. Now can we get off the topic of Mary's sex life and get back to promoting Jesus' teachings?
