My view, which I have expressed often, is that by definition there is no shortage of vocations to the priesthood.  The church is constituted by the Eucharist; no Eucharist, no church.  The first and greatest responsibility of a bishop is to provide for the celebration of the Eucharist and the sacraments in his local church. The institutional church has established barriers based on sex and marital status, but these are not of God.  God sends the church the priests it needs; the church must allow women and married men to respond to the call they hear and to test their vocations in formation and in service to the community.
