“Indeed, I counsel, warn and exhort my friars in the Lord Jesus Christ, that when they go about through the world, they not quarrel nor contend in words, nor judge others, but be mild, peaceable and modest, meek and humble, speaking uprightly to all, as is fitting. And that they ought not ride horseback, unless they are driven to do so by manifest necessity or infirmity. Into whatever house they have entered, let them first say: "Peace to this house." And according to the Holy Gospel let it be licit to eat of all the foods, which are placed before them.”
(St. Francis, Definitive Rule)
