The Dignity of the Human Person: Source of Catholic Teaching
You’ve heard the accusatory questions. “Why is the Catholic Church always trying to tell people how to live their lives? Why does it force its views of the moral life on women in particular?”
These and similar questions may be earnestly felt, but they reflect a deep and common error. The Church, like so many other institutions, proposes what she believes to be true. She obviously doesn’t force anyone to believe anything, as evidenced by the many Catholics who are confused about what the Church teaches and thus disagree.
But it is important to understand that there is a specific line of reasoning to why the Church thinks what she thinks, particularly with regard to contraception.
Based in philosophy, theology, science and pastoral and personal experience, the Church carefully considers key questions over time, announcing positions as the truth comes to light. Her teaching on contraception may be her most controversial in today’s hyper-sexualized culture, but it is also among her most consistent and prophetic. It is based on how the Church has always understood human nature, and how this basic understanding of who we are leads to what we must do in order to flourish, which is the basic goal of the moral life.
Here we present a very brief summary of the serious philosophy and theology that underlies Church’s line of reasoning in her moral teaching. We invite you to do your own research starting with the resources we present at the conclusion of this article. For more on the specific teachings of the Church on marriage and contraception, see here.
Human Dignity and Morality
The Catholic Church teaches that the moral life consists in choosing those actions and developing those virtues by means of which people pursue their own good and the good of others, and enter into communion with God, their Supreme Good.1
This definition of the moral life is based on the Church’s view of the human person and his dignity, as well as what is truly best for him. Human dignity refers to the intrinsic and absolute value of the human person for the mere fact that he or she is a person, and not because of his or her race, religion, achievements, age, health, or any other characteristic. As stated in the Catechism of the Catholic Church, “The human person is the only creature on earth that God has willed for its own sake” (CCC 1703).
We can find the source of the dignity of the human person in Scripture: “God created man in his own image, in the image of God he created him, male and female he created them.” (Genesis 1:27).
We also find the truth of human dignity from Scripture confirmed by reason and experience. To truly love another person is to want his or her true flourishing, and this holds true regardless of one’s theological or philosophical training. The greatest thinkers of the Church teach us to treat others as ends in themselves and not as mere means to an end. In other words, we should treat all human beings as persons who possess the same gift of freedom that we ourselves possess, and not as things to be used.2
Human Nature: Body and Soul
The Bible also teaches us that the human person is a unity of body and soul: “Then the LORD God formed man of dust from the ground, and breathed into his nostrils the breath of life; and man became a living being” (Genesis 2:7).
Human reason has also reflected on and refined this ancient truth about the unity of the human person. Saint Thomas Aquinas acknowledged that even before the birth of Jesus, Aristotle held that the body is substantially, or essentially, united to the soul.3 And since a person’s body is an intrinsic dimension of himself, it is not like a vestment that he can choose to wear or not. The human body is not simply a complex organism; it is a human body, the body of a person.4
Male and Female Dignity
From this it follows that the human body expresses the human person as he or she is in himself or herself, including the sexual aspect of the person.5 God has created the human person only as male and female, and this has great significance for the smallest unit of society, the natural family, and thus for larger communities.
If indeed the body is substantially united to the soul, then the body shares in the dignity of the soul and of the image of God. This means that the way God has created the human body has moral importance, because it is a good that should be respected and promoted. We can say that the way God has created the bodies of man and woman is his first message to us as to the way they ought to behave (CCC 364).
The Bible, reason and experience also teach us that man and woman are equal in dignity, yet different and complementary. Man and woman complement each other spiritually, psychologically and physically—especially in the conjugal act (CCC 372). By means of this act the spouses unite themselves intimately in love and at the same time are capable of bringing into the world a new human being, who is also created in the image of God.6 How great is this gift – to be co-creators with God in bringing forth new life!
The Catholic Church, following the teachings of Jesus, also teaches that true love is the sincere and total gift of oneself to the beloved.7 But this self-gift can only be achieved through authentic freedom. Authentic freedom is the ability to control one’s selfishness in order to choose to do the good of the other, even when it requires personal sacrifice.8
True love also enables human persons to go beyond themselves and participate with God in the co-creation of another human life.7 The image of God in the human person is best expressed in the union of man and woman in marriage, because by means of it they reflect God’s creative love in bringing into the world a new human person, also created in the image of God.9
There is a great deal that we have presented here, for which reason we recommend that you consider the sources in the endnotes, take seminars on key teachings from faithful and qualified teachers, and consider these ideas prayerfully.
We hope that in your prayerful consideration of Church teaching you will come to find what many former atheists and former non-Catholic Christians have found, namely, that the Church’s arguments about the moral life make a great deal more sense than the assumptions of our culture at large.
