will become evident soon to all the faithful
That word ‘soon’ again.
from a simple minded layperson, not a well learned theologian....
I doubt there a was a well-learned theologian among the 12 Jesus chose to be his apostles. Yet they lived in his presence, knew him, but did not always understand.
The light comes from God, made visible through Christ and the Holy Spirit.
We can be one of those well-learned theologian and profess to have full ‘knowledge’ of the light and all its complexities, but also continue to live in darkness, preferring to use our knowledge of the light to expose the darkness abiding in others, seeing their shadows but unable to see our own shadow when we come face to face with the light.
A priest once said to me: “We are all theologians!” He meant in respect that all of us are created with a knowledge of God and to seek and recognise the nature of the Divine.
St Augustine of Hippo said: "You have made us for yourself, O Lord, and our hearts are restless until they find their rest in you." He defined theology as "reasoning or discussion concerning the Deity.”
I suppose it can also be said in this regard, scientists too are theologians. They seek to reveal aspects of God’s creation some of us will never understand or ever meant to.
