11 Refusing to human life any sacred or spiritual character, such a doctrine logically makes of marriage and the family a purely artificial and civil institution, the outcome of a specific economic system. There exists no matrimonial bond of a juridico-moral nature that is not subject to the whim of the individual or of the collectivity. Naturally, therefore, the notion of an indissoluble marriage-tie is scouted. Communism is particularly characterized by the rejection of any link that binds woman to the family and the home, and her emancipation is proclaimed as a basic principle. She is withdrawn from the family and the care of her children, to be thrust instead into public life and collective production under the same conditions as man. The care of home and children then devolves upon the collectivity. Finally, the right of education is denied to parents, for it is conceived as the exclusive prerogative of the community, in whose name and by whose mandate alone parents may exercise this right.
