If you think about it, soul and spirit both derive, Biblically, from the Hebrew terms for 'wind' or 'breath'.
The emphasis I would put say here is
movement.
One tends to see the soul as a concrete thing, as 'the essence of me' – we say 'save our souls' and we traditionally count the number of travellers on a journey as 'souls'. When a ship sinks, it does so at the loss of some or all souls on board ... that kind of thing.
Whereas spirit is much more fluid and dynamic. We speak of the spirit of an occasion, or the spirit of place, the spirit within me that move me from one to place to another, from one feeling to another.
The term that speaks most of the individual spirit to me is μετάνοια
metanoia.
Commonly and traditionally translated as 'repentance', a more literal meaning is a 'change of mind', 'of thinking', 'of intention', or 'of the heart'.
Metanoia implies, in the New Testament, a change in the disposition toward God. And equally a positive change towards life, or knowledge. Neither
change of mind nor
change of heart carries quite the force or vigour of the Greek word. And in this instance, 'heart' should be understood as it was in the classical sense: as the seat of both the intellect and the passions.
Could we get to know our individual spirit as a means of better connecting with God?
Short answer – yes – but I can only answer in a Catholic context.
As an example of a standing spiritual disposition is that of the Centurion in Matthew 8:8:
"Lord, I am not worthy that you should come in under my roof; but only declare it by a word and my servant will be healed."
The kind of
metanoia we are more usually thinking of is the more dynamic – the apprehension of the real in the face of experience, as evidenced by Peter in Mark 8:29: "Thou art the Christ" and Thomas in John 20:28: "My Lord and my God."
But the calling to us is different, we are not faced with Christ in the Transfiguration on Mount Tabor, nor with the Risen saviour in the Upper Room. Ours is a much more subtle and nuanced calling:
Jesus perpetually says:
"But whom do you say that I am?" (Mark 8:29, Matthew 16:15, Luke 9:20) and when we plead ignorance, He says:
"If you had known me you would also have recognised my Father. From this moment you know and have seen him." Philip says to him, "Lord, show us the Father, and for us that suffices." Jesus says to him, "I am with you for such a long time, Philip, and you have not known me? Whoever has seen me has seen the Father. How can you say, 'Show us the Father'? Do you not believe that I am in the Father and the Father is in me?" (John 14:7-10).
Metanoia is not conversion is the face of personal some epiphany. Metanoia is a personal and conscious decision to open the mind and the heart to the possibility. Epiphany comes later.
