On the holy priesthood & the grace of God

(This) grace is so exceeding great that were men able to see the glory of this grace, the whole world would wonder at it; but the Lord has veiled it that His servants should not be puffed up but find salvation in humility...Truly noble is a priest - the minister at God's altar. Whoever gives offense to him offends the Holy Spirit who lives in him... If people could behold in what glory a priest celebrates the divine office they would swoon at the sight; and if the priest could see himself, could see the celestial glory surrounding him as he officiates, he would become a great warrior and devote himself to feats of spiritual endurance, that he might not offend in any way the grace of the Holy Spirit living in him.
