Contemplations on Christianity

The recent articles in the news about Anglicans being allowed to become part of the Roman Catholic church whilst still retaining some of their Anglican identity has got me thinking about all the differing branches of Christianity that exist with their varied views and styles of worship. Are some branches right and others wrong or are we just choosing to sing different songs from the same underlying hymnbook? Are we seeing the same God from different perspectives or are we in danger of creating our own god which sits more comfortably with our own views and beliefs about the world?
