The word liminal comes from the Latin word for threshold. The word makes it into English as lentel, the piece over a door that holds the doorframe in place. Liminality is the condition of being \"neither here nor there,\" neither \"this or that.\" An airport is thus a liminal space, in which one feels situated in some place other than his origin or destination. The Holy Spirit is the liminal face of God, leading us from where we are, to someplace not yet seen or experienced.
