The term “Eucharist” is derived from the Greek for “thanksgiving.” This form of prayer reaches its apex in the celebration of the Eucharist, in which we participate in Christ’s offering of Himself to the Father, in a salvific work that encompasses the entire cosmos.
As the Catechism explains, “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.”
Because Christ is the Head and we are the members of His Body, we too are integrally involved in this action. When we make our own offerings at Mass – of our time, resources, and most of all ourselves – all are taken up and absorbed into Jesus’ perfect sacrifice of thanksgiving.
But our thanksgiving is not limited to the Mass itself. Anything that we experience can become an occasion for thanksgiving. Although it is obviously easier to render thanks in happy circumstances, we should also learn to thank God even in our trials. St. Paul exhorts us to “give thanks in all circumstances; for this is the will of God in Christ Jesus for you” (1 Thess 5:18).
By offering thanksgiving to God in the midst of difficulties, we grow in trust, knowing that the Lord is ordering all things for our eternal welfare. In this way we keep our earthly lives in the proper perspective of our ultimate destiny.
God did not have to create us at all, or share with us His own divine life. If we maintain a spirit of gratitude for God’s great works of creation, redemption, and sanctification – which we could never merit on our own – we can better shoulder the burdens of daily life.
