John 20:17 (King James Version) states: “Jesus saith unto her, Touch me not; for I am not yet ascended to my Father: but go to my brethren, and say unto them, I ascend unto my Father, and your Father; and to my God, and your God.”
To put this scripture in the proper context we will need to read the entire passage. In summary, Christ was resurrected and Mary Magdalene was the first of his followers to see him.
The Greek word for “touch” in this passage of scripture is: “haptomai” which means “to adhere to” “fasten” or “to cling.” Speculation of the passage might suggest that Mary Magdalene was holding on to Christ or clinging to him (as suggested by many translations) as if to prevent him for leaving. The statement “for I am not yet ascended to my Father” suggests that he wasn’t planning to leave right away to go to the Father and there may be additional opportunities for which she could see him before his final departure.
