The criticism of Bernadin is that his approach has been misused by pro-abortion politicians to justify their support of abortion. Rep. Nancy Pelosi, for instance, can justify spending federal dollars on "family planning services" because reducing the number of poor people (by keeping them from being born, presumably) has an economic payoff.
But that approach is indefensible using Bernadin's logic (and, no matter what Pelosi says, not Catholic). If you tear opposition to abortion out of the "seamless garment," your position on poverty, global warning, or whatever is ruined. If you don't care about the life of an unborn child, your defense of the lives of the poor is diminished at best, destroyed at worst.
The Jerseyville Ministerial Alliance has a book club. We were exiled from the monthly meeting because not everyone wanted to allot part of our 2 hour meeting to discussing a book. Nevertheless, a few of us continue to meet to discuss an agreed upon book between regular meetings. Most recently, we read Pope Benedict's encyclical Caritas in Veritate.
The encyclical deals with the global economic crisis, but it does so with what seems to be a "seamless" approach to life. Central to any discussion about human development, economic recovery, environmental protection, business ethics, etc. has to be an openness to life. "Openness to life is at the center of human development," argues the pope.
While Esolen's warning about missed opportunities is well heard, the misuse of a consistent life ethic doesn't make it invalid. It only makes those who misuse it look foolish.
