The Church needs to guide people to chastity, not accept unchastity and counsel condom use.
I don't think anyone
here is advocating unchastity. The reality is, though, people have always
had to deal with temptations to unchastity, and often failed- the Bible is full of stories where people were unchaste, and indeed, the geneology of Our Lord Jesus Christ includes people who were unchaste. In St. Matthew's geneology of the ancestors of Our Lord, he lists among Christ's ancestors:
1) Tamar who conceived through incest with her father-in-law;
2) Rahab who was a prostitute, and
3) Bathsheba who was an adultress.
Unchastity is a powerful passion which is difficult to overcome for many (if not most). People will
stumble, but thanks be to God who in His mercy allows repentance.
Imagine for a minute that you are the father of a teenage son. Let's say that your son does not agree with your ideas about chastity. Would you tell him not to use condoms in the hope that he would remain chaste? Will you be pleased if, by not using condoms, he contracted the HIV virus? Of course you wouldn't! In the same way, if the Church forbids and opposes the production and provision of condoms, she is condemning to death those who fall into sin.
It's not about promoting unchastity, it's about saving lives. Millions are dying of AIDS in Africa, millions of infants have been left orphaned because of the AIDS crisis there. In countries where there was a rapid reponse to the AIDS crisis (such as Australia) which responded with education programs promoting safer sex, ans safer injecting drug use, AIDS has been, for the most part, controlled. This was not the case in Africa, which is why we have the disaster which exists there now.
