Gregory the Great — as excerpted in the Catena Aurea on John 20:10-18

“(Hom. xxv.) Perhaps, however, the woman was right in believing Jesus to be the gardener. Was not He the spiritual Gardener, who by the power of His love had sown strong seeds of virtue in her breast? But how is it that, as soon as she sees the gardener, as she supposes Him to be, she says, without having told Him who it was she was seeking, Sir, if Thou hast borne Him hence? It arises from her love; when one loves a person, one never thinks that any one else can be ignorant of him. Our Lord, after calling her by the common name of her sex, and not being recognised, calls her by her own name: Jesus saith unto her, Mary; as if to say, Recognise Him, who recognises thee. Mary, being called by name, recognises Him; that it was He whom she sought externally, and He who taught her internally to seek: She turned herself, and saith unto Him, Rabboni; which is to say, Master.”
