Jesus spoke seven last words from the Cross. Each time he did it, he had to push down on his feet and raise his body to fill his lungs with air so he could speak.
I’m sitting here with a broken foot, I can only imagine the terrible pain he endured. Indeed our corpus Christis have been too mild — in no way do they show the actual number of wounds that Christ sustained for our sins.
Bless Anne Catherine Emmerich has some good information on this from revelations to her, and I believe Mel Givson used them.
