Some times you get married in a certain church to appease the future inlaws.  Problems such as which church are easier to work out without the normal stresses and emotions of a wedding.  And they did work out quite well for all.

Would love to address the rest of the theoligy in your post, but it loses much in the typed word and does not allow for the piece by piece interaction that a face to face discussion allows.  I love debating religion, but it truely is a subject that needs time and interaction.

I will end by saying the Catholic religion could have prevented the Lutheran religion from being born by answering Martin Luther's 97 thesis or points of clarification instead of trying to sweep him out the door.  Luther's desire was not to harm Catholicism, but to steer it back to the Biblical basis.  Hence, man again destroys what the Creator wished to endow.

AND, you are right, there is only one Lord and Saviour, Jesus Christ, for all of us.  And he prefers to have all of us as his sheep.
