I think it was clearly intended by MGS4 that The Boss had become almost a religious figure for Zero and Big Boss, especially with all the imagery in the church and accompanying cutscenes. But then Zero made Big Boss into an equally symbolic icon as well, being her last disciple, which Big Boss resented. The differing ideologies and the conflict that resulted is analogous to many schisms that occur between fanatical devotes, although not just in religion.
