Second Vatican Council
December 7, 1965
Coming down to practical and particularly urgent consequences, this council lays stress on reverence for man; everyone must consider his every neighbor without exception as another self, taking into account first of all His life and the means necessary to living it with dignity,(8) so as not to imitate the rich man who had no concern for the poor man Lazarus.(9)
In our times a special obligation binds us to make ourselves the neighbor of every person without exception. and of actively helping him when he comes across our path, whether he be an old person abandoned by all, a foreign laborer unjustly looked down upon, a refugee, a child born of an unlawful union and wrongly suffering for a sin he did not commit, or a hungry person who disturbs our conscience by recalling the voice of the Lord, "As long as you did it for one of these the least of my brethren, you did it for me" (Matt. 25:40).
Furthermore, whatever is opposed to life itself, such as any type of murder, genocide, abortion, euthanasia or willful self-destruction, whatever violates the integrity of the human person, such as mutilation, torments inflicted on body or mind, attempts to coerce the will itself; whatever insults human dignity, such as subhuman living conditions, arbitrary imprisonment, deportation, slavery, prostitution, the selling of women and children; as well as disgraceful working conditions, where men are treated as mere tools for profit, rather than as free and responsible persons; all these things and others of their like are infamies indeed. They poison human society, but they do more harm to those who practice them than those who suffer from the injury. Moreover, they are supreme dishonor to the Creator.
To these problems there are those who presume to offer dishonorable solutions indeed; they do not recoil even from the taking of life. But the Church issues the reminder that a true contradiction cannot exist between the divine laws pertaining to the transmission of life and those pertaining to authentic conjugal love.
For God, the Lord of life, has conferred on men the surpassing ministry of safeguarding life in a manner which is worthy of man. Therefore from the moment of its conception life must be guarded with the greatest care while abortion and infanticide are unspeakable crimes....
...All should be persuaded that human life and the task of transmitting it are not realities bound up with this world alone. Hence they cannot be measured or perceived only in terms of it, but always have a bearing on the eternal destiny of men.
