(Please read the Scripture passage before reading the homily.)
The kingdom of heaven is like . . . . a mustard seed; yeast.
The parable of the mustard seed begins in a garden. The mustard seed is small, about the size of a pinhole. It grows and, in a way, fills the world. It reminds me of another garden in which two small people lived, and their expanse has taken over the whole world. It also reminds me of another garden, in which a person lay in death until the tomb exploded and resurrection filled the world.
The parable of the yeast starts with a woman mixing yeast into over 300 cups of flour, enough to feed all the birds of the sky or all the people coming to the feast of the Lamb.
The kingdom of God starts small and takes over the world: nothing can stop the kingdom of God. The kingdom of God acts like yeast that seems to hide itself in the dough only to make the dough do two things: rise up to fill the earth and become tasty and delicious.
Bread without yeast has not much taste, and the world squandering in sin had not must taste or glamor. When the yeast of the kingdom of heaven started working the dullness of sin wass replaced with the beauty of grace.
The kingdom of heaven is like a mustard seed and like a mustard seed. There is much theology in these parables.
