The Bible doesn’t specify that He exclusively and specifically appeared to Mary Magdalen first. It only records how the apostles first got word of the resurrection via Mary Magdalen who saw Him before the apostles did. Interestingly in the private revelation writings of the mystic Anne Catherine Emmerich, she wrote that Jesus appeared to Mary His mother:
"It was towards eleven o’clock at night when the Blessed Virgin, incited by irrepressible feelings of love, arose, wrapped a gray cloak around her, and left the house quite alone. . . . I saw her go first to the house of Caiphas, and then to the palace of Pilate, which was at a great distance off; I watched her through the whole of her solitary journey along that part which had been trodden by her Son, loaded with his heavy Cross; she stopped at every place where our Saviour had suffered particularly, or had received any fresh outrage from his barbarous enemies. Her appearance, as she walked slowly along, was that of a person seeking something; she often bent down to the ground, touched the stones with her hands, and then inundated them with kisses, if the precious blood of her beloved Son was upon them. God granted her at this time particular lights and graces, and she was able without the slightest degree of difficulty to distinguish every place sanctified by his sufferings. . . Mary then went to Calvary . . .
. . . I then saw the glorified body of our Lord rise up, and it passed through the hard rock as easily as if the latter had been formed of some ductile substance. The earth shook, and an angel in the garb of a warrior descended from Heaven with the speed of lightning, entered the tomb, lifted the stone, placed it on the right side, and seated himself upon it. At this tremendous sight the soldiers fell to the ground, and remained there apparently lifeless. . .
At the very moment in which the angel entered the sepulchre and the earth quaked, I saw our Lord appear to his holy Mother on Calvary. His body was beautiful and lightsome, and its beauty was that of a celestial being. He was clothed in a large mantle, which at one moment looked dazzlingly white, as it floated through the air, waving to and fro with every breath of wind, and the next reflected a thousand brilliant colours as the sunbeams passed over it. His large open wounds shone brightly, and could be seen from a great distance: the wounds in his hands were so large that a finger might be put into them without difficulty; and rays of light proceeded from them, diverging in the direction of his fingers. The souls of the patriarchs bowed down before the Mother of our Saviour, and Jesus spoke to her concerning his Resurrection, telling her many things which I have forgotten. He showed her his wounds; and Mary prostrated to kiss his sacred feet; but he took her hand, raised her, and disappeared.
