In this thesis The influence of faith and religiosity on a person’s depression, we will adress the topic of depression, which is an ever-present disease in today’s society. The aim of this paper is to show how spirituality affects people with depressive disorder, and how a holistic approach can help to treat depression. The paper consists of three parts. In the first chapter of the paper, in order to understand depressive disorder, we will talk in general about depression, the types of depression and its symptoms, and how depression affects a person's life. In the second chapter, we will talk about the influence of faith and religiosity on a person’s depression, and about its positive and negative influence. We will also talk about the positive impact of spirituality and how spirituality can help to prevent and cure depression. Then we will talk about pastoral care for people with depression. In the third chapter, we will talk about spiritual therapies and about the holistic approach to depression. Especially, we will focus on logotherapy and hagiotherapy, which emphasize the spiritual dimension of a person and highlight the positive effects of spirituality and religiosity and how it helps people suffering from depression. Depression is a serious illness that people face every day. Our goal is to point out the meaning of life and that the center of life is not the illness, but faith and religiosity that contribute to the meaning of a person’s life. A man who turns to God's love and responds to it with love becomes saved and healthier.
