Whether Christ was in the tomb only one day and two nights?

Objections

Objection 1 : It would seem that Christ was not in the tomb during only one day and two nights; because He said (Mt. 12:40): "As Jonas was in the whale's belly three days and three nights: so shall the Son of man be in the heart of the earth three days and three nights." But He was in the heart of the earth while He was in the grave. Therefore He was not in the tomb for only one day and two nights.
Objection 2 : Gregory says in a Paschal Homily (Hom. xxi): "As Samson carried off the gates of Gaza during the night, even so Christ rose in the night, taking away the gates of hell." But after rising He was not in the tomb. Therefore He was not two whole nights in the grave.
Objection 3 : Further, light prevailed over darkness by Christ's death. But night belongs to darkness, and day to light. Therefore it was more fitting for Christ's body to be in the tomb for two days and a night, rather than conversely.
