“And He was crucified for us under Pontius Pilate, and suffered and was buried.”
The Creed is clear that Jesus was crucified, suffered, died, and buried. But by buried they mean put in sepulcher. For burial was not like modern day burial where we put them in a hole in the ground.
When Jesus died is laid out by the phrase “under Pontius Pilate.” This seems very important.
It might be good to mention that the Creed gives us no theory of the atonement, and so none required. They all agreed that Jesus died for our sins, but what that meant was open.
