Irish people always had a deep spirituality and a strong belief in supernatural. With the advent of Christianity, superstition and rituals such as pilgrimages around Holy Wells and climbing Croagh Patrick were incorporated into Christian ritual.

Throughout the nineteenth and early twentieth centuries the Christian message of a better life in the hereafter was a powerful moral support for the poor people who had to cope with their very difficult conditions and extreme deprivation; often religion was the only source of comfort available.

In nineteenth century priests and nuns played a crucial role in the development of Irish educational system replacing "Hedge Scholls" with formal schooling and this further contributed to a central role of religion in Irish life.
