Since the bulletin article is due while I am still in Phoenix, here is a sermon by St. Peter Chrysologus (5th century) on the Gospel:
Yes, it is true: a mustard seed is indeed an image of the kingdom of God.
Christ is the kingdom of heaven. Sown like a mustard seed in the garden of the Virgin's womb, he grew up into the tree of the cross whose branches stretch across the world. Crushed in the mortar of the passion, its fruit has produced seasoning enough for the flavoring and preservation of every living creature with which it comes in contact.
As long as a mustard seed remains intact, its properties lie dormant; but when it is crushed they are exceedingly evident. So it was with Christ; he chose to have his body crushed, because he would not have his power concealed.
We too must crush this mustard seed, in order to feel the force of this parable... Christ became all things in order to restore all of us in himself. The man Christ received the mustard seed which represents the kingdom of God; as man he received it, though as God he had always possessed it. He sowed it in his gar- den, that is in his bride, the Church.
The Church is a garden extending over the whole world, tilled by the plough of the gospel, fenced in by stakes of doctrine and discipline, cleared of every harmful weed by the labor of the apostles, fragrant and lovely with perennial flowers: virgins' lilies and martyrs' roses set amid the pleasant verdure of all who bear witness to Christ and the tender plants of all who have faith in him.
Such then is the mustard seed which Christ sowed in his garden. When he promised a kingdom to the patriarchs the seed took root in them; with the proph- ets it sprang up, with the apostles it grew tall, in the Church it became a great tree putting forth innumerable branches laden with gifts. And now you too must take the wings of the psalmist's dove, gleaming gold in the rays of divine sunlight, and fly to rest for ever among those sturdy, fruitful branches. No snares are set to trap you there; fly off, then, with confidence and dwell securely in its shelter.
God bless you all and God bless our fathers this Fathers’ Day!
