"16 Jesus said to her, “Mary!” She turned and said to him in Hebrew, “Rabbouni,” which means Teacher.17 Jesus said to her, “Stop holding on to me, for I have not yet ascended to the Father. But go to my brothers and tell them, ‘I am going to my Father and your Father, to my God and your God.’”
"30. The bond between seeing and hearing in faith-knowledge is most clearly evident in John’s Gospel.
For the Fourth Gospel, to believe is both to hear and to see.
Faith’s hearing emerges as a form of knowing proper to love: it is a personal hearing, one which recognizes the voice of the Good Shepherd (cf. Jn 10:3-5); it is a hearing which calls for discipleship, as was the case with the first disciples:
"Hearing him say these things, they followed Jesus" (Jn 1:37).
But faith is also tied to sight.
Seeing the signs which Jesus worked leads at times to faith, as in the case of the Jews who, following the raising of Lazarus, "having seen what he did, believed in him" (Jn 11:45). At other times, faith itself leads to deeper vision:
"If you believe, you will see the glory of God" (Jn 11:40).
In the end, belief and sight intersect:
"Whoever believes in me believes in him who sent me. And whoever sees me sees him who sent me" (Jn 12:44-45).
Joined to hearing, seeing then becomes a form of following Christ, and faith appears as a process of gazing, in which our eyes grow accustomed to peering into the depths.
Easter morning thus passes from John who, standing in the early morning darkness before the empty tomb, "saw and believed" (Jn 20:8), to Mary Magdalene who, after seeing Jesus (cf. Jn 20:14) and wanting to cling to him, is asked to contemplate him as he ascends to the Father, and finally to her full confession before the disciples:
"I have seen the Lord!" (Jn 20:18)."
