The four gospels give different accounts of who got to the tomb first, and what they saw. Christian apologists have always struggled to reconcile the discrepancies in this, the most important story in their entire faith. The efforts are still continuing today. For example
HERE, and
HERE
But none of the so-called 'witnesses' (Mary Magdalene, plus one, or two, or several, others) are said to have actually witnessed the resurrection itself; only the empty tomb, with one or two angels, or one or two men, there.
the only persons who are said to have witnessed the resurrection itself were the guards (note, these are probably not the same guards who were present at the crucifixion). The guards were 'as dead men' at first, and then quietly trotted off to tell the high priest Jesus had just got up and walked out of his tomb. Then they accepted a 'large bribe' to put the word about that the disciples had stolen the body to make it look as if Jesus was really the Son of God. And sure enough, the guards pocketed the cash and went around telling a lie about what had happened. As you would, wouldn't you, if you had just seen an angel descend clothed in lightning, and a guy
who claimed to be the son of god had just come back to life and walked out of his tomb after being dead 36 hours?
That's exactly what you would do, isn't it?
And, FTM, who told Matthew about the high priest's act of secret bribery?
