Have a look at the different versions of Jn 20:16 relating to the post-Resurrection appearance of Jesus to Mary Magdalene :
Jesus said to her, Mary! Turning around she said to Him in Hebrew, Rabboni!—which means Teacher or Master. (RMPC)
Jesus said to her, “Mary.” Turning around, she said to him in Aramaic, “Rabboni!”—which means “Teacher.” (CSB)
Compare the salutation of Mary with that of the Apostles :
Now Thomas (also known as Didymus), one of the Twelve, was not with the disciples when Jesus came. So the other disciples told him, “We have seen the Lord!” (Jn 20:24-25)
And that of `Doubting Thomas ':
Thomas said to him, “My Lord and my God!” (Jn 20:28).
Now, the salutation `Teacher'is not something you use for someone who you know, has been dead for three days and and is suddenly appearing before you in a not-so-easily recognizable form. In retrospect , we see Mary mistaking Jesus for the gardener (Jn 20:15).
Of course, we hear Mary telling the disciples that she saw the Lord (Jn 20:18) . But her initial reaction to the appearance puts one in doubt if she really understood that she was looking at the Risen Lord. My question therefore is: According to Catholic scholars, did Mary Magdalene understand at the garden that Jesus had risen from the dead ?
