Rossi de Gasperis, in Sentieri di vita, p 603, cites Heb 10:5-10, and Rom 12:1-2. His comment:
To offer the body means offering the whole of the history lived in this body and this flesh, the use i have made of my intelligence and of my will, of my memory and of my sensibility, the joys and the sorrows, the victories and the defeats, the grace and the repentance for sins, the love given and the pardon received, good health and bad, strength and weakness, and so on. All this becomes, through our freedom, material for our liturgy, our offering, our sacrifice.
if this is kept in mind and in heart, there will be no danger at all of empty ritualism. The rite does not swallow the substance; it is rather the substance that swallows every ritual!
Paul goes on:
Whether you eat or drink, or do any other thing, do it all for the glory of God. (1 Cor 10:31)
And whatever you do in word or deed, do it all in the name of the Lord Jesus, giving praise through him to God the Father. (Col 3:17)
None of you, in fact, lives for himself or dies for himself, because if we live, we live for the Lord; if we die, we die for the Lord. So whether we live or die, we are therefore in the Lord. (Rom 14:7-8)
