In the early Church, during the Persecution of Christians---a good number of Christians fled to the deserts to live the life of monasticism or as anchorites.  They developed STRONG spiritual lives and wrote about it. We have their documents to this day [Apophthegmata Patrum].  

Jesus brought/brings us Salvation, not the priests.  To develop a deep spiritual life, priests are not essential.  Those priests who are spiritual directors are wonderful.  But they are not ESSENTIAL to developing a deep relationship with the Trinity.

And do you think that the Holy Trinity will be stymied if Catholics won't have the number of priests available?  Don't count on it!
