The human person is created out of love, for love and is destined to flourish. God, who is perfect love, has created each person in the image and likeness of God. Each person is unique and equal in dignity to all others. Persons are rational and free beings having both a body and a soul. Human beings are in relationship to all of God's creation. God has made each person in the Divine image and likeness as an inseparable unity of body, mind and spirit. God gifts each individual with absolute and enduring dignity and the unconditional love of God. Through God the human person has the possibility of life lived to the full.
The Catholic perspective promotes human dignity, the essential worth or dignity of the human person as made in the image and likeness of God. Each human being is unique and unrepeatable and loved and called by God. This means that every human being, in every circumstance, is good. This is not to say that they are morally good. Our moral goodness or moral badness is based on the moral decisions we make. Rather, to affirm the worth or dignity of the human person is to affirm that it is a good thing that he or she exists, that his or her existence is desired by God and that his or her existence is worthwhile. The dignity of the human person is the foundation of a moral vision for society (United States Conference of Catholic Bishops, 2013). Catholic thinking about sexuality and relationships is based on this basic affirmation of the equal worth of all human beings.
The sanctity of life is one way of giving expression to this basic affirmation of the worth or dignity of all human beings. When the Catholic Church affirms the sanctity of life it affirms that it is good that a particular human being exists rather than the reverse. the existence of each human person is willed by God and human beings have no right to destroy that existence. To say that life is sacred is to say, no matter who you are, no matter what you have done, no matter what you will do, the simple fact that you exist as a specific human being is enough for you to be considered worthy of life, worthy of respect and worthy of those things that will help you to flourish rather than perish.
