Faith not only leads to the soul being made like the divine Word, full of grace, free, and blessed, but it unites the soul with Christ as a bride with her bridegroom. From this marriage it follows (as St. Paul says, Eph v.30) that Christ and the soul become one body; and in this they have all things in common, be they good or ill, so that what belongs to Christ now belongs to the believing soul, and what belongs to the soul now belongs to Christ. Since Christ possesses every good and blessedness, these now belong to the soul. Since the soul is burdened with sin and wretchedness, these now become Christ's.—Martin Luther, Freedom of the Christian
The husband is the head of the wife just in so far as he is to her what Christ is to the Church. He is to love her as God loved the Church—read on—and gave his life for her. This headship, then, is most fully embodied in the husband we should all wish to be, but in him whose marriage is most like a crucifixion... C. S. Lewis, The Business of Heaven, pp. 169, 170.
