Gardens have a deep significance in the history of salvation and in the experience of God's people.
'....Saint John takes up all these experiences and gives a theological interpretation to the place when he says: "across the Kidron valley, where there was a garden" (18.1) This same highly evocative word comes back at the end of the Passion narrative: "In the place where he was crucified there was a garden, and in the garden a new tomb where no one had ever been laid." (19.41) John's use of the word "garden" is an unmistakable reference to the story of Paradise and the Fall. That story, he tells us, is being resumed here. It is in the "garden" that Jesus is betrayed, but the garden is also the place of the Resurrection. It was in the garden that Jesus fully accepted the Father's will, made it his own, and thus changed the course of history.'Pope Benedict XVI 'Jesus of Nazareth' (Vol 2)
