It is a community of members, of parents and children, of brothers and sisters, who belong together and live together by divine will, and in which we are members and participants apart from any consent on our part, by virtue of the same divine will.
The diversity both attracts and repels, unifies and isolates; sometimes the family is a small kingdom divided against itself, but such division can be intense because the unity is generally so deep and solid. From day to day that unity in diversity is maintained by the father, and especially by the mother; a communal language, religion, and morality, communal traditions, relationships, and interests, communal experiences of love and suffering, of joy and sorrow, of sickness and recovery, of death and grief, all preserve the unity and keep it in balance with the diversity.
