Priests for life? I thought all priests were for life... or do I just live under a rock?
You are correct. They are all supposed to be for life. Some of them focus on life issues, though.
So, some as with Food for the Poor priests would focus a great deal on poverty issues, and meet the routine needs of the people under their care as well.
Priests for Life focus on educating people about abortion and related life issues, and meet the routine needs of the people under their care as well.
There are other orders that focus on education in poorly educated areas...
They all care about abortion, life issues, education, and poverty, but noone can concentrate on every human need 24/7. So, they specialize.
