Christian Prayer›SECTION ONE PRAYER IN THE CHRISTIAN LIFE›CHAPTER ONE THE REVELATION OF PRAYER - THE UNIVERSAL CALL TO PRAYER›IV. Prayer of Thanksgiving
Thanksgiving characterizes the prayer of the Church which, in celebrating the Eucharist, reveals and becomes more fully what she is. Indeed, in the work of salvation, Christ sets creation free from sin and death to consecrate it anew and make it return to the Father, for his glory. the thanksgiving of the members of the Body participates in that of their Head.
