Pope Gregory IX Against Helping The Saracens (Muslims)

Pope Gregory IX, Rachel Suum Videns, Nov. 17, 1234: “… to be unwilling to confound malicious men is nothing other than to support them, nor does one who refrains from opposing a manifest evildoer lack the secret guilt of association… In addition, we renew the sentence of excommunication promulgated at the Fourth Lateran Council against those who deliver weapons, iron, and timber suitable for ships to the Saracens [Muslims], whoever fulfills the office of pilot in the piratical ships of Saracens [Muslims], or lends them any kind of counsel or aid in constructing war machines or anything else to the detriment of the Holy Land.”
