Or perhaps let's not.
I was in my doctor's office this morning and they had (I kid you not) al jazeera running on the TV. The current conflict in Gaza was being discussed and "reported" on and it made me wonder, as they were showing bodies of women and children being pulled out of piles of rubble, should we condemn Judaism for the actions of the Israeli government. OR will we, like my Protestant parents and myself for that matter, say that Israel must defend itself against aggression and people who want to see the entire nation destroyed?
There are parallels between the situation in the Holy Land today and the history of the Church dealing with aggressive heretics. Lethal force is being used against a hostile but civilian population because one religion doesn't want another religion to exist.
I say there can be no more peace with islam than there could have been with the cathars or albigensians.
Except the Cathars and Albigensians were nonviolent. Which of course you know. So you also know that your comparison of them with murderous Muslims is a deliberate lie.
An excellent comparison, however, is with the Christians who are being slaughtered by the Muslims because they exist, or the Jews who are receiving rockets everyday because they exist. That's exactly why the Church murdered the Cathars - because they existed.
Why lie? Why defend the indefensible? Why not simply say that the Church rejects Cathars teachings, but their slaughter was wrong even for the time. Something done by perverts in the Church for their own power, and not reflecting the teachings of the Church, let alone the teachings of Christ. Why continue to try to defend horror with lies? Do you think Christ wants that? If not, then who do you really serve?
