"Professionalizing the staff depersonalized the care."
The above quote was said about mental health care in the 20th Century. The same can be said about ministry in the church. There is much that can be said biblically against clergyizing God's servants. At the same time, in practical terms, when spiritual service becomes a career, the "care" of others, or dedication to the work of God, is redirected to furthering one's prospects of professional development and monetary gain. It cannot otherwise be so. A whole industry arises to perpetuate the professional class and cater to their needs.
