In the two parables that make up the text of today, we once again find the mention of a man and a woman. While in the first parable of the mustard seed, it is a “man” who sows, in the second parable of the yeast; it is a “woman” who mixes it. The parable of the mustard seed is found also in Mark and Matthew, whereas the parable of the yeast is in Matthew but not in Mark.
The Lukan version of the parable of the mustard seed is the shortest of the three. It lacks the description of the mustard seed as the smallest of all seeds (Mt 13:31; Mk 4:31) or the mature plant as “the greatest of all shrubs” (Mt 13:32; Mk 4:32). The point that Luke seems to be making by omitting these details is that rather than compare the kingdom to a mighty cedar, be describes it is terms of an insignificant seed. The emphasis is not on future glory, but on the present sign of its presence, even though it cannot be seen as clearly as some would like to. In Luke, it is a parable of the beginnings of the kingdom and not on its final manifestation. The people expected a spectacular, extra-ordinary cedar, but Jesus preferred to bring the kingdom as insignificantly as a mustard seed.
The point of the parable of the yeast in Luke is not the same as the point being made in the parable of the mustard seed. In this parable it is a clearly a case of small beginnings contrasted with great endings. While the quantity of yeast is not specified, the use of the word “hid’ indicates that it is an extremely small quantity. In contrast the three measures of flour that are leavened are the equivalent of fifty pounds of flour, enough to make bread for about 0ne hundred fifty people. The kingdom like the yeast will eventually leaven the whole of humanity.
While the parable of the mustard seed dramatises the presence of the kingdom in its insignificant beginnings, the parable of the yeast reminds us that even small beginnings are powerful and eventually change the character of the whole.
When we realise that with the motley crew that Jesus chose he could achieve so much in the world, then we realise that his words in the parable are indeed true. The kingdom does have insignificant beginnings, but even this insignificant or small beginning has resulted and will continue to result in great endings.
