How do we compare abortion to other social justice issues?

On the Catholic.com site, as a banner message during the election period, there was a quote from John Paul II concerning the politics of abortion versus social issues. Can you post for me what document was being quoted?

I believe the quote to which you are referring is as follows:

The inviolability of the person which is a reflection of the absolute inviolability of God, fínds its primary and fundamental expression in the inviolability of human life. Above all, the common outcry, which is justly made on behalf of human rights – for example, the right to health, to home, to work, to family, to culture – is false and illusory if the right to life, the most basic and fundamental right and the condition for all other personal rights, is not defended with maximum determination (Christifideles Laici 38).
