The message of the Pope was that faith is born of the soul, not the body. Whoever would lead someone to faith needs the ability to speak well and to reason properly, without violence and threats. To convince a reasonable soul, one does not need a strong arm, or weapons of any kind, or any other means of threatening a person with death.

Contrast this message with the teachings of the Prophet Muhammad in the matter of spreading Islamic faith to the rejecters of truth (infidels) after truth has become evident to them:

"Kill them wherever you find them and drive them out [of the place] from which they drove you out and [remember] persecution is worse than carnage. But do not initiate war with them near the Holy Kabah unless they attack you there. But if they attack you, put them to the sword [without any hesitation]. Thus shall such disbelievers be rewarded. However, if they desist [from this disbelief], Allah is Forgiving and Merciful. Keep fighting against them, until persecution does not remain and [in the land of Arabia] Allah's religion reigns supreme. But if they mend their ways, then [you should know that] an offensive is only allowed against the evildoers. A sacred month for a sacred month; [similarly] other sacred things too are subject to retaliation. So if any one transgresses against you, you should also pay back in equal coins. Have fear of Allah and [keep in mind that] Allah is with those who remain within the bounds [stipulated by religion]." (Qu'ran, 2:190-194)

Quite a mouthful!
