text: You are correct in what you say.  The issue is that the priesthood, like marriage, is a vocation, not just a career or job. Many Protestants do not see ministry as a vocation, they see it is a career or job.  This is why it is so difficult for them to understand the Catholic priesthood.  Comparing the priesthood with Protestant pastors or ministry is an apples to oranges comparison.  
  
  If the priesthood was just a career path, your point would be more valid. It isn't just a matter of balancing family life with a career--but trying to literally balance two vocations.  In that sense the person is trying to serve two masters because he gave his life to two masters.  It can be done--and has been done, and may be done again.  That does not make it ideal.  
  
  It is not ideal because--again we are not talking about balancing family with career or job--but managing two vocations.  A vocation is who you are, a career or job is what you do.
