As most contemporary theologians will tell you - traditionalists included - is that "theology" is not at all required to minister to and serve the Church and its Founder.  It is the grace that comes from our belief in Jesus Christ that is the "fuel" for carrying out the themes of the Gospels.  The world isn't "hungry" for the "truth" of theology!  The world is literally hungry for human decency, dignity, respect, and Love.  Those are the things we as Christians (including priests) are called to provide without exclusions of qualification.
