Three domestic parables, and lots of questions

Brothers and sisters: Be subject to one another out of reverence for Christ.

  Wives, be subject to your husbands as you are to the Lord. For the husband is the head of the wife just as Christ is the head of the church, the body of which he is the Savior. Just as the church is subject to Christ, so also wives ought to be, in everything, to their husbands.

  Husbands, love your wives, just as Christ loved the church and gave himself up for her, in order to make her holy by cleansing her with the washing of water by the word, so as to present the church to himself in splendor, without a spot or wrinkle or anything of the kind—yes, so that she may be holy and without blemish. In the same way, husbands should love their wives as they do their own bodies. He who loves his wife loves himself. For no one ever hates his own body, but he nourishes and tenderly cares for it, just as Christ does for the church, because we are members of his body. “For this reason a man will leave his father and mother and be joined to his wife, and the two will become one flesh.” This is a great mystery, and I am applying it to Christ and the church. Each of you, however, should love his wife as himself, and a wife should respect her husband.

Luke 13:18-21

Jesus said, “What is the kingdom of God like? And to what should I compare it? It is like a mustard seed that someone took and sowed in the garden; it grew and became a tree, and the birds of the air made nests in its branches.”

  And again he said, “To what should I compare the kingdom of God? It is like yeast that a woman took and mixed in with three measures of flour until all of it was leavened.”
