In a letter by pope John Paul II I found the following quote where he talks about God as 'the Other'. I know this term is used in phenomenology and by Levinas, Lacan and perhaps others, but I was wondering to which thinker, theologian or area of philosophy or theology he was referring to when he uses 'the Other' instead of God. Does he (or other prominent catholics) use this term in other letters or books?
We must confess that we all have need of this silence, filled with the presence of him who is adored: in theology, so as to exploit fully its own sapiential and spiritual soul; in prayer, so that we may never forget that seeing God means coming down the mountain with a face so radiant that we are obliged to cover it with a veil (cf. Ex 34:33), and that our gatherings may make room for God's presence and avoid self - celebration; in preaching, so as not to delude ourselves that it is enough to heap word upon word to attract people to the experience of God; in commitment, so that we will refuse to be locked in a struggle without love and forgiveness. This is what man needs today; he is often unable to be silent for fear of meeting himself, of feeling the emptiness that asks itself about meaning; man who deafens himself with noise. All, believers and non - believers alike, need to learn a silence that allows the Other to speak when and how he wishes, and allows us to understand his words.
-- John Paul II, Orientale Lumen 16 (1996)
