hi eagle
you said:”The only condition for salvation is faith in Christ...not fighting in the Crusades.”
I am sorry you are categorically wrong - nowhere will you find that Urban II made fighting in the Crusades a ‘condition of salvation’.
You will need to find the quotation from a papal bull, encyclical, etc. exactly where he stated that - otherwise it is just a figment of your protestant imagination.
Ad Majoram Dei Gloriam
For the Greater Glory of God
All who die by the way, whether by land or by sea, or in battle against the pagans, shall have immediate remission of sins. This I grant them through the power of God with which I am invested.
sure sounds like it to me.
