In our belief it is impossible to live in the presence of God without a choice companion to whom you are sealed for eternity. Are you saying that the Apostle Paul, indeed any Christian who died before your Joseph Smith made this rule, is not living in the presence of God?
I'm implying that the Apostle Paul, who was a fellow Apostle with Joseph Smith and thus knew about the "rule" as well as the Prophet Joseph did, is sealed to someone already.
Just because someone chooses to revere out-of-context correspondence, and to misinterpret its contents, doesn't mean ALL of us do.
