Noli me tangere

λέγει αὐτῇ Ἰησοῦς· μή μου ἅπτου, οὔπω γὰρ ἀναβέβηκα πρὸς τὸν πατέρα· πορεύου δὲ πρὸς τοὺς ἀδελφούς μου καὶ εἰπὲ αὐτοῖς ἀναβαίνω πρὸς τὸν πατέρα μου καὶ πατέρα ὑμῶν καὶ θεόν μου καὶ θεὸν ὑμῶν.

Jesus saith to her, Touch me not; for I am not yet ascended to my Father; but go to my brethren, and say to them, I ascend to my Father and your Father, and to my God and your God.

 -- John 20:17

17. Touch me not. 
This appears not to agree with the narrative of Matthew; for he expressly says, that the women held him By The Feet, and worshipped him, (Matthew 28:9.) Now, since he allowed himself to be touched by his disciples, what reason was there for forbidding Mary to touch him? The answer is easy, provided that we remember that the women were not repelled from touching Christ, till their eagerness to touch him had been carried to excess; for, so far as it was necessary for removing doubt, he unquestionably did not forbid them to touch him, but, perceiving that their attention was too much occupied with embracing his feet, he restrained and corrected that immoderate zeal. They fixed their attention on his bodily presence, and did not understand any other way of enjoying his society than by conversing with him on the earth. We ought, therefore, to conclude, that they were not forbidden to touch him, until Christ saw that, by their foolish and unreasonable desire, they wished to keep him in the world.

For I am not yet ascended to my Father. 
We ought to attend to this reason which he adds; for by these words he enjoins the women to restrain their feelings, until he be received into the heavenly glory. In short, he pointed out the design of his resurrection; not such as they had imagined it to be, that, after having returned to life, he should triumph in the world, but rather that, by his ascension to heaven, he should enter into the possession of the kingdom which had been promised to him, and, seated at the right hand of the Father, should govern the Church by the power of his Spirit. The meaning of the words therefore is, that his state of resurrection would not be full and complete, until he should sit down in heaven at the right hand of the Father; and, therefore, that the women did wrong in satisfying themselves with having nothing more than the half of his resurrection, and desiring to enjoy his presence in the world. This doctrine yields two advantages. The first is, that those who are desirous to succeed in seeking Christ must raise their minds upwards; and the second is, that all who endeavor to go to him must rid themselves of the earthly affections of the flesh, as Paul exhorts,

"If ye then be risen with Christ seek those things which are above, where Christ sitteth at the right hand of God," (Colossians 3:1)
