Does Jesus’ purification after death apply to all or just to him? In the 20th chapter of John verse 17 Jesus forbad Mary Magdalene touching him, stating that he had not yet ascended to the Father:


  John 20:17  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.


Then in verse 27 he challenges Thomas to touch his wounds, indicating that he had at that time ascended to the Father.


  John 20:27  Then saith he to Thomas, Reach hither thy finger, and behold my hands; and reach hither thy hand, and thrust it into my side: and be not faithless, but believing. 


The stark difference in touching Jesus would indicate that Jesus had undergone some type of purification after verse 17 but prior to verse 27.

Is there any Protestant Denomination; which purposes that that purification process is necessary for all believers, or is it generally accepted that only Jesus required this purification?
Christ was always perfect and pure.

Joh 8:46  Which of you convinceth me of sin? And if I say the truth, why do ye not believe me? 

Heb 4:15  For we have not an high priest which cannot be touched with the feeling of our infirmities; but was in all points tempted like as we are, yet without sin. 

Heb 7:26  For such an high priest became us, who is holy, harmless, undefiled, separate from sinners, and made higher than the heavens; 

To suggest He needed purification is therefore a contradiction of the Scriptures and blasphemy.

None are purified after death because :

Heb 10:9  Then said he, Lo, I come to do thy will, O God. He taketh away the first, that he may establish the second. 
Heb 10:10  By the which will we are sanctified through the offering of the body of Jesus Christ once for all. 

Heb 10:14  For by one offering he hath perfected for ever them that are sanctified. 

To suggest otherwise is therefore also a contradiction of Scripture, and a blasphemy against Christ's perfect sacrifice.
