Here is hoping the bishops take heed and do some creative thinking, realistic planning, and listening to the Spirit.  

I don't know if there is a shortage of those who want to be a priest as much as there is a shortage of acceptance in the hearts of bishops/hierarchy to the clear message from the Holy Spirit that married men and married/unmarried women are also called to the priesthood.  

I also think that the "package" that is presented as the practice of the faith is also a big problem.  That includes the roles of priests, hierarchy and lay,  the rituals of the Mass,  what is and is not a sacrament and all the rules about them.  And, it includes major elements of the faith that are derived from ancient writings, parables taken as literal truth, and ancient tribal customs enshrined as eternal absolutes.  

But, one step at the time.  A good first step is to end the all male, celibate priesthood and recognize the priesthood of the Baptized.  Time for bishops to take a step forward.
