The Adornment of the Spiritual Marriage, by Jan van Ruysbroeck, , at sacred-texts.com
From this humility there springs obedience, for none can be inwardly obedient save the humble man.
Obedience means an unassuming, submissive, and pliable humour, and a will in readiness for all that is good. Obedience makes a man submit to the biddings, the forbiddings, and the will of God; it subjects the senses and the animal powers to the higher reason, so that a man may live decently and reasonably. And it makes men submissive and obedient to Holy Church, to the sacraments, to the prelates and their teaching, to their commandments and their counsels, and to all the good customs practised by Holy Christendom. It also makes a man ready and supple in his intercourse with other men, in deed and counsel, in ghostly and bodily business, with prudent discretion, according to the needs of each.
And it casts out disobedience, that daughter of pride, more to be abhorred than venom or poison. To be obedient in will and deed adorns and enlarges and reveals the humility of a man. It makes peace in the cloister. If it is in the prelate, as it ought to be, it will draw to him all those whom he rules. It makes for peace and unanimity between equals; and he who has it is loved by his superiors and by those who are set over him; whilst by God he is advanced, and enriched with His gifts, which are eternal.
