I assume by 'we' you mean the church. If so - what're you trying to say? That the church will trade death of believers/anyone for the truth? What has truth got to do with anything anyway?
The truth would be worth promoting. Wouldnt it?
First of all, lets confirm here, that the Catholic Church promotes abstenience, and sex inside marriage without protection. If this is what the local priests are promoting, then no responsibility for the AIDS epidemic in Africa should be accounted by the Catholic Church.
Lets examine this further. The African populous can be viewed as two groups of people. Those who obey the churches commandments and people who do not, (matters not of religion). For people who do obey the church, it would represent abstenience, meaning decreased HIV/AIDS transferrence. In this case, it does not spread, but rather stops the epidemic of AIDS.
In case two where people do not obey the church. Then abstenience is going to be defyed. In this case, it stands not against reason that protection should be used, if abstenience is defyed. If one "commandment" is disobeyed, why obey the other one.If people cannot upkeep their sexual desires, then why blame the church. And this is the state in Africa. No matter how I disagree with Catholicism's sexual policy inside marriage.
What it comes down to is the lack of education. The requirement of protection for casual sex, in order to stop the spread of AIDS needs to be affirmed by its goverment/other groups. It is not up to the Church to do it. They are merely for the propagation of theology.
