Three of the nine proposals on life issues from the Aparecida bishops involve group effort of some sort. First choice, a conference:
c) Promote forums, panels, seminars, and congresses to study, consider, and analyze concrete contemporary issues about life in all its manifestations, and especially in the human being, particularly with regard to respect for life from conception to its natural death.
Catholic institutions of higher learning are a good location:
d) Ask Catholic universities to organize bioethics programs accessible to all and to take a public stand on the major issues of bioethics.
Take a clear stance as well as promote the dialogue and learning.
Bishops can also assemble their own groups, not only for education and study, but also involvement in the discussions that must take place in the public sphere:
e) Create an ethics and bioethics committee in Bishops Conferences, with persons trained in the matter to guarantee fidelity and respect for the teaching of the Church’s magisterium on life, so that it can serve as a venue for researching, studying, discussing, and updating the community when public debate so requires. This committee shall confront the situations that arise in that locality, the country, or the world to define and promote life at the proper time.
