text: Interesting your reference to CL.  Is this part of revision of CL? Was it always in CL?
  Diocesan clergy were not protected by CL when they decamped.  Some sued to get compensation.  Some had more benign bishops who personally intervened. Most walked away with empty pockets.   Holding financial control over individuals makes it difficult to  leave especially advanced in years as one is hardly marketable. 
  Taking vows is a contested issue.  Jesus counseled not to take oaths (Matt. 5:34).  But oaths are big in the RCC. One might quibble between vows and oaths  but a rose by any other name is still a rose.
