If experts in biology, medicine, and psychology work together for joint research, they can greatly contribute to the happiness of marriage and family and to peace of conscience. - 52, Gaudium et Spes, DOCUMENTS OF THE SECOND VATICAN COUNCIL

 The study of humans is called Anthropology. Since I became a priest, I have taught a subject called anthropology in University. It was a comprehensive study of human nature, covering biological, medical, psychological backgrounds and philosophical fields beginning with human origins. Although approaches to biology, medicine, and sociology to humans were also meaningful, psychological approaches were the most interesting to me.

It was a great shock to me that men and women were clearly different and that the mysterious providence of why God created men and women. The Catholic Church has already declared that men and women should live without discrimination and respect each other for 2,000 years. However, the argument that men and women should be the same in every way is also rejected. Because men and women are not the same, but equal.

Men and women in the Catholic Church are not discriminated against and differ, and they are also distinguished, try to help each other, understand each other, and work together to complement each other is a complementary relationship. Some of the world's voices that claim that men and women should be called men and women is discrimination, and that women and men should be called men, from the Catholic Church's point of view, are puns. I just don't want to laugh.

Men and women are so different, their perspectives, directions, and consciousness are different. How different are neighbors who have unique personalities, whether they are next to me or women? The neighbors next to us have different views on me and society. Also, the perspective of a man or woman is different. It's actually hard to find a neighbor who has the same thought and judgment and a consistent view.

Why do we have to live with different people in different situations with completely different thoughts? It is clear that we are different from each other, and honest conversations based on this fact are of great help to live together, that is, toward coexistence. The attitude of trying to affirm and understand the other person's thoughts is essential. Just by keeping my mouth shut, tracking the other person's consciousness, and listening, I open my heart and actively participate in the conversation.

The way to get to know, affirm, and present hope to him is also meaningful to watch BTS videos and listen to songs. But I go beyond these steps and ask for God's power and I am sure that God works through me as a powerful tool for this world to live together. The study of exploring and studying different human sources can contribute greatly to the happiness of marriage and family through joint research such as medicine, biology, and psychology.

The Catholic Church reminds the priests that it is their duty to promote marriage and family well-being, and that it is their duty to encourage those who live in families, and provides a basis for how the study of theology and psychology should be co-studied.

Those too who are skilled in other sciences, notably the medical, biological, social and psychological, can considerably advance the welfare of marriage and the family along with peace of conscience if by pooling their efforts they labor to explain more thoroughly the various conditions favoring a proper regulation of births.

It devolves on priests duly trained about family matters to nurture the vocation of spouses by a variety of pastoral means, by preaching God's word, by liturgical worship, and by other spiritual aids to conjugal and family life; to sustain them sympathetically and patiently in difficulties, and to make them courageous through love, so that families which are truly illustrious can be formed.
