Matthew 27:52-53 KJV
(52) And the graves were opened; and many bodies of the saints which slept arose,
(53) And came out of the graves after his resurrection, and went into the holy city, and appeared unto many.
Raised from the grave in mortal bodies or celestial bodies?
Tambora,
Matthew 27:50-53
Jesus, when he had cried again with a loud voice, yielded up the ghost.
51 And, behold, the veil of the temple was rent in twain from the top to the bottom; and the earth did quake, and the rocks rent;
52 And the graves were opened; and many bodies of the saints which slept arose,
53 And came out of the graves after his resurrection, and went into the holy city, and appeared unto many.
Most people do not seem to understand what is actually said there.
When did they supposedly arise? At the death of Jesus.
When did they come out of the graves after they arose? More than three days and nights later????? Matthew 12:40
The answer to your question is neither, those two verses never happened. It is another case of forgery, an early one.
