The bride's symbolic vision of the church, its explanation, which concerns the moderation and attitude that the pope ought to maintain regarding his own person and regarding the cardinals and other prelates of Holy Mother Church, and especially about the attitude of humility.
Book 4 - Chapter 49 SAINT BRIDGET PATRON SAINT OF EUROPE FINAL PART
Let him then organize his entourage with moderation and keep only those servants needed to protect him. Although it is in God's hands to call him to judgment, still it is only right for him to have servants both in order to strengthen the cause of justice and so that he can humble those who rebel against God and against the holy customs of the church.

The hinge-pins attached to the doors represent the cardinals who have been bent outward and stretched as far as possible toward all pride, greed, and physical pleasure. This is why the pope should take a hammer and tongs in hand and bend the hinges to his will by not letting them have more clothes, servants, and equipment than necessity and utility require. Let him bend them with the tongs, that is, with his soothing words and divine counsel and fatherly love. Then, if they refuse to obey, he should take the hammer and display severity toward them, doing with them whatever lies in his power and does not go against justice, until they are bent to his will.

The floor represents the bishops and the secular clergy, whose greed is bottomless. From their pride and luxurious way of living come the fumes that make all the angels in heaven and all God's friends on earth shun them.

The pope can improve the situation greatly by allowing them to have only what they need and nothing superfluous, and he should order each bishop to watch over the ways of his own clergy. Anyone who refuses to mend his ways and live continently should be stripped of his prebends, because God would rather not have a mass said in a given place than let a whorish hand touch the body of God."
