In Humanae Vitae (1968), Pope Paul VI gave the follow guidance to public officials on life issues:
“To rulers, who are those principally responsible for the common good, and who can do so much to safeguard moral customs, we say: Do not allow the morality of your peoples to be degraded; do not permit that by legal means practices contrary to the natural and divine law be introduced into that fundamental cell, the family.
“Quite other is the way in which public authorities can and must contribute to the solution of the demographic problem: namely, the way of a provident policy for the family, of a wise education of peoples in respect of moral law and the liberty of citizens.”
