As we do not know the concepts that you studied, we are not able to pick from these. However, we can still provide examples of social psychology concepts that could be relevant in a Christian context:
Altruism
Altruism refers to the moral practice of being concerned about the well-being and happiness of others, whether these are humans or animals. Most of the time, an altruistic person would derive spiritual and mental satisfaction from engaging in behaviours that ensure the well-being of others. This is important to Christians because the Bible asks them to be charitable towards others. Moreover, the Bible also encourages them to care about their neighbours.
Theory of mind
The theory of mind is the ability to identify and attribute mental states to ourselves and others. This also allows us to understand that we might have beliefs, desires and intentions that are different from one another's. The theory of mind is important to Christianity because it allows Christians to understand their purpose in life, their connection to God and their place in the world.
Empathy
Empathy refers to the capacity of a person to understand others, and to think of things from their point of view. It is the capacity to put oneself in another's position. Empathy is important for Christians because it allows them to feel closer to others. Moreover, it enables them to feel more charitable towards others, and to think of everyone as children of God.
