The concept of identity expresses the innate human desire to form a coherent sense of self through making free choices about who we want to be and what we want to do in the context of relationships. 'This includes, but is not limited to, the realms of gender, ethnicity, culture, social role, age group, personality, religion, spirituality, religious community, marital status, vowed life status, and sexuality' (Kappler, 2014). These relationships are formative for our identity in that they exert positive and negative influences on who we think we are and the roles we think we play. Moreover, as our place in these relationships changes over time, new expectations and opportunities arise to make choices to either embrace or reject these new roles as part of our sense of self. Whether we like it or not, these choices become part of our personal identities. We all experience being a child. When we are children no matter how much we might want to think of ourselves as adults we remain children.  Becoming parents or deciding not to have children has a certain objective impact on our identities. Once a person has a child, regardless of their actual relationship with that child, being a parent becomes part of their identity. The ways in which we respond to the objective dimensions of our identity arising from our relationships to the world, to others, to institutions, and to time and history contributes to the formation of our own sense of self in the world and the formation of the way other people see us.

Men and Women are fundamentally equal. Man and woman are both human beings. Theologically speaking the creation of human beings precedes the creation of the sexes. Women and men are of equal worth or dignity in the eyes of God. Both male and female are made in God's image and both are called to share in the future God promises. Yet, this fundamental equality does not mean that being a man and being a woman is the same thing. Rather it is equally good to be man as it is to be a woman and neither sex should think of itself as superior in some fundamental or essential way to the other. Man and woman share the same humanity. They are both made in God's image sharing a basic mutuality. Both are called to live in a covenant of love (United States Conference of Catholic Bishops, 1991). Consequently, sexism, that is, the unjust discrimination to the detriment of a person on the basis of his or her sex is not to be tolerated. Since all human beings, whether male or female, share the same dignity or moral worth each gender has an equal claim to the natural human rights that proceed from this worth. Similarly, each gender has a duty to work for the common good and to respect the dignity and rights of others. True, all human beings are not alike from the point of view of varying physical power and the diversity of intellectual and moral resources. Nevertheless, with respect to the fundamental rights of the person, every type of discrimination, whether social or cultural, whether based on sex, race, color, social condition, language or religion, is to be overcome and eradicated as contrary to God's intent (Vatican Council II, Gaudium et Spes, para. 29).
