Gregory the Dialogist : And we know that in the tabernacle of God not only bowls but also, by the Lord's command, cups were made. By bowls, indeed, abundant teaching is designated; by cups, however, small and limited knowledge. One person, full of the teaching of truth, intoxicates the minds of his hearers. By what he says, therefore, he surely offers a bowl. Another cannot fully express what he perceives, but because he proclaims it in some way, he surely offers a taste through a cup. Therefore, placed in God's tabernacle, that is, in the holy Church, if you cannot minister bowls through the wisdom of teaching, give to your neighbors cups of a good word insofar as you are able according to divine generosity. Insofar as you perceive yourselves to have progressed, draw others along with you; desire to have companions on the way to God. — Forty Gospel Homilies, Homily 6
