This one was put to the apologists:
When, during the mass, is the sacrifice made. Is it at the words of consecration, or during the breaking of the Eucharistic?
Father Vincent Serpa, always aided by the Holy Spirit, was quick to point out in part:
The sacrifice was made on Calvary on Good Friday.
I have noted a spate of recent inquisitions, so to speak, from a certain brand of fellow Christians. It seems there is a script, a design or ??? intent upon proving that Catholics re-sacrifice Christ at each mass. Of course, this will fail, but does it appear that this question may not have been completely sincere?
