Humble Ourselves At Every Opportunity

The ministers and preachers must remember that they do not have the right to the office of serving the friars or of preaching, and they must be prepared to lay it aside without objection the moment they are told to do so. In that love which is God (1 John 4:8), I entreat all my friars, whether they are given to preaching, praying, or manual labour, to do their best to humble themselves at every opportunity; not to boast or be self-satisfied, or take pride in any good which God says or does or accomplishes in them or by them...
