There really is no need for theologians any more.  At most, their job should be to study everything ever spoken or written by Pope Saint John Paul II the Magnificent, and his chosen Disciple, Benedict 16, and explain how we, the laity, can best obey those teachings.  There is no need to open the Bible or pick out statements attributed to Jesus--The Saint said it all, closed all doors, and solidified all we can ever know or understand of God's Will and Nature.  All that is left is obedience, penance, monetary contributions and of course, Obedience.
