The husband is an image of Christ for the family; he is the priest of the family and holds both the responsibility for the spiritual upbringing of the children and well-being of the entire family. The wife, as the image of the Church, submits to this responsibility and authority and does not usurp it. This means the converse is true: if the husband fails to live out this role, he will answer to God. Part of this means the parents providing a unified front before the children in spiritual matters, both parents, following the husband’s leadership ensuring that all spiritual obligations are met.
The passage goes to to liken the husband’s role to that of Christ and his sacrificial death. This means the husband’s authority is a sacrificial one: he has to give of himself for the temporal and spiritual needs of his family, just as Jesus did for his Church. That is why the husband is commanded to love his wife in the same way. The wife also needs to submit to his love, in other words, let her husband love her and sacrifice for her.
This is not a call for men to lord it over their wives no matter what: the exhortation is to both the husbands and the wives and their roles in Christian marriage.
