How we treat the most vulnerable people speaks more about our Society than anything else. The infants and children, the sick, disabled and the elderly are among the most vulnerable. As the earliest time a person can be a person is from conception we as Catholics should be defending the lives of all from conception to grave.
As touched on the ability to work and be a productive member of Society is also important. While there is a visible face of the Church in the Pro-Life movement, and a very vocal one, one does not have to look far to see the Social Services provided to those already born from cradle to grave. From orphanages, and homes for women who are pregnant, have children, or medical care, vocational training, drug and alcohol treatment, food banks, and care of the elderly and disabled, the Catholic Church established these programs before any State programs, and continues them today
