In Contraception and the Mind of Christ, HLI's regional coordinator for Portuguese-speaking nations, Raymond de Souza, explains why the Church teaches that contraception is not morally permissiblie.

Drawing from Pope Paul VI's courageous encyclical, Humanae vitae, Raymond implores us to learn the "mind of Christ."  We should not simply follow what is acceptable in society, but follow God's laws using a well-formed conscience.  We need to keep our souls AND bodies pure because humans consist of both body and soul.  Raymond also explains why contraception is against the natural law.  If you or someone you know has ever questioned why the Church teaches such a counter-cultural view of marriage, listen to this audio talk for the answer!
