By Patti Maguire Armstrong, National Catholic Register - “Without the sisters, I would close tomorrow,” Father Jeff Bayhi, founder of Metanoia Manor in Louisiana, says of the Catholic sisters who help staff the only accredited treatment home for adolescent girls who are trafficked in the United States... “No one can do anything like Catholic sisters can,” according to John Clegg, volunteer director for Sisters of Mary World Villages for Children, which cares for 20,000 poor children annually in six countries. “They are the most saintly, humble, loving and caring human beings I know.”.. Perhaps the most unsung heroes in the world are Catholic sisters who have taken on the role of mothers for children without parents to provide for them.
