“And so its only knowledge is how to call back the souls of the deceased from the very highway of death, to straighten the feeble, to heal the sick, to cleanse the devil-possessed, to open the bars of the prison, to loose the bands. of the innocent. It also absolves sins, drives back temptations, quenches persecutions, strengthens the weak-hearted, delights the high-minded, brings home wayfarers, stills the waves, confounds robbers, feeds the poor, rules the rich, lifts up the fallen, supports the unstable, upholds them that stand.
The angels too pray, all of them. The whole creation prays. Cattle and wild beasts pray, and bend their knees, and in coming forth from their stalls and lairs look up to heaven, their mouth not idle, making the spirit move in their own fashion. Moreover the birds taking flight lift themselves up to heaven and instead of hands spread out the cross of their wings, while saying something which may be supposed to be a prayer. What more then of the obligation of prayer? Even the Lord himself prayed: to him be honour and power for ever and ever.
