The subject of the analysis performed by the author were the names of God in the songs recorded in the “Church Songbook”, by Rev. Jan Siedlecki. It is a relatively large collection of nominations the centre of which contains a collection of the names related to God the Father, successively to the Son of God Jesus Christ and the Holy Spirit. There are also frequent references to “Lord, Creator, Lamb of God”. The use of a given name depends on Christian dogmas and the prayer purposes of the speech acts.
