Just as the four parts of the Cross hold together and are linked by their central point, so sublimity and depth are coupled by the power of God, forming that space in which every visible and invisible creature is contained. … It is raising-up for all those lying down, fulcrum for those who are standing, cane for the he infirm, shepherd’s staff for the sheep, aid for those who mend their ways, perfection for the departing, salvation of body and soul, rejection of evils, cause of all good things, destruction of sin, blueprint for the resurrection, and the wood of eternal life.
