Francis has divided the church?  

Go back to 1978, use CARA data or even the Vatican's Annual publication of church statitstics, and trace  the course of the divisions in the church, and of the losses of church members. 

 Francis is not the cause, he is trying to heal the divisions that took place long before he was elected.  It will fail, most likely, because of the staunch opposition of the bishops appointed by his predecessors and of those who admire the viewpoints of those bishops. They want Francis to fail. 

The hemorraging of Catholics from the western church accelerated after 1978, and continued to accelerate for the next three+ decades. The fall in numbers of priests and women religious followed the same downward course.  This course has not been reversed, and is not likely to be reversed quickly - if ever.  But the cause of the loss of tens of millions of cradle Catholics, and of the divisions among those who remain, cannot be laid at the door of Pope Francis.
