YOUCAT Question n. 483 - What are the names of the five main types of prayer?

(Youcat answer) The five main types of prayer are blessing and adoration, prayer of petition, prayer of intercession, prayer of thanksgiving, and prayer of praise.

A deepening through CCC

(CCC  2644) The Holy Spirit who teaches the Church and recalls to her all that Jesus said also instructs her in the life of prayer, inspiring new expressions of the same basic forms of prayer: blessing, petition, intercession, thanksgiving, and praise. (CCC 2626) Blessing expresses the basic movement of Christian prayer: it is an encounter between God and man. In blessing, God's gift and man's acceptance of it are united in dialogue with each other. The prayer of blessing is man's response to God's gifts: because God blesses, the human heart can in return bless the One who is the source of every blessing. 

  Reflecting and meditating 

(CCC Comment)

(CCC 2643) The Eucharist contains and expresses all forms of prayer: it is "the pure offering" of the whole Body of Christ to the glory of God's name (Cf. Mal 1:11) and, according to the traditions of East and West, it is the "sacrifice of praise."

(The next question is:  What is a prayer of blessing?)
