Answer:
People attend churches. The church building is a geographical location that provides sanctuary.
Biblically, there is a specified design for how a holy sanctuary should look like. This is found in the Good Book from the 25th Chapter of Exodus to the 31st.
It is clear, however, that over the course of history, those recommendations have been modified.
These changes, some mostly triggered by the radical liturgical activities of the Second Vatican Council, the Catholic Church (which holds Church Building Architecture with utmost reverence and importance) has found it greatly challenging to adopt a newer and better standard architecturally to express its Mass.
For the Catholic church, it is important that the geographical location has a sense of sanctity and sacredness which will serve to enhance the unique spiritual experience of the Catholic Mass.
The above being said, the architectural devices of the church that exude space and a sense of sacredness works together with the liturgical processes to create evoke or amplify an emotional response.
The emotional response in this case relates to the connection between the church attendee and the sacredness they have come to want to achieve.
