John Calvin on John 20:15

15. Lord, if thou hast carried him hence. She calls him Lord, according to the custom of her nation; for the same appellation, Lord, (Κύριε The salutation, Κύριε was addressed to persons of various ranks, and answers to the modern term, Sir. — Ed. ) is employed by the Hebrews in addressing laborers and other persons of low condition. We see that Mary has no view of this matter but what is earthly. She desires only to obtain the dead body of Christ, that she may keep it hidden in the sepulcher; but she leaves out the most important matter, the elevation of her mind to the divine power of his resurrection. We need not wonder, therefore, if such grovelling views place a veil before her eyes.

John 20:16-18

16. Jesus saith to her, Mary! She turned herself, and said to him, Rabboni! which means, Master! 17. 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. 18. Mary Magdalene went and told the disciples that she had seen the Lord, and that he had said these things to her.
