A bishop, or anyone, when told that "there is nothing you can do" in the face of an anti-life decision should never be satisfied with such a response. There is ALWAYS something that any of us can do in the face of the culture of death.
Prayer is first.
Witness is second.
Dialogue is third.
All of these avenues must be pursued for LIFE at all levels and at all times.
It is never acceptable to "do nothing" in response to attacks against life in any of its stages and conditions, from the moment of conception until natural death.
Christ fights for every life in His death throes on the cross, with every breath left to Him. Can we not do the same? Fight for life with every breath, every word, every action and every beat of the heart.
"Doing nothing" is never an acceptable answer for those who love life.
