Kyrie Eleison "Lord have mercy" spoken walking up a Tunnel in a 15th century fortress

In The New Testament Kyrie Eleison means "Lord have mercy" and it is the position of all those that come before God. The attitude of choosing God is the teachings of the devil. In this video am at a 15th century fortress walking up a tunnel and did not know it would look as it did before making this video.
