St Joan of Arc to the Hussites

Jesus, Mary
For a long time the rumor and voice of the people have reported to me, Joan the Maiden, that from true Christians you have become heretics, and like the Saracens you have ruined the true faith and worship, and embraced a disgraceful and unlawful superstition; and wishing to sustain and spread it there is not a disgraceful thing nor foolish belief which you would not dare. You spoil the sacraments of the Church, you tear up the articles of the Faith, you destroy the churches, you break and burn the statues which were set up as memorials, you massacre Christians because they preserve the true Faith. What is this fury? Or what rage or madness consumes you? This faith, which God Almighty, the Son, and the Holy Spirit have revealed, established, elevated to power, and glorified a thousand ways through miracles - you persecute this Faith, you wish to overthrow and destroy it. You are blind, but not because you lack eyes or understanding. Do you believe that you will remain unpunished for it? Or are you unaware that God opposes your unlawful efforts and will not permit you to remain in darkness and error? So that the more you indulge yourselves in crime and sacrilege, the more He will prepare great punishments and anguish for you.

As far as I am concerned, to tell you frankly, if I wasn't occupied in the English wars I would have come to see you a long time ago; but if I don't find out that you have reformed yourselves I might leave off [fighting] the English and go against you, so that by the sword [lit. - "by iron"], if I can't do it any other way, I will eliminate your mad and obscene superstition and remove your heresy or your life; but if you would prefer to return to the Catholic faith and the original Light, then send your ambassadors to me and I will tell them what you need to do; if [on the other hand] you are not willing and if you obstinately resist the spur,n9 remember what damage and offenses you have committed and await me, who will inflict similar upon you with forces human and divine.

St Joan of Arc, if she did not move with the times, why should we?

French bishops take note!
